          <p>A drag image is shown when a DragImageList is supplied at all, 
            <b>and</b> when no accepting target is under the mouse, or the source control style includes csDisplayDragImage, or AlwaysShowDragImage is set in the DragObject.</p>
          <p>In drag-dock operations typically no drag image is shown, since the DockRect frame already gives all required visual feedback.</p>
          <pre>This is a vague idea of the usage of this class:

SetDragImage selects an image from the list, and defines the hotspot within this image.
  (the hotspot typically is the offset of the mouse position to the origin of the dragged control)

BeginDrag starts dragging, the image is shown at the starting location.

DragMove moves the image.

EndDrag stops dragging, the image is removed from the screen.

          <remark>AutoCreated DragObjects imply different behaviour in the DragOver and DragDrop events, where the Source becomes the dragged control, while else the DragObject itself is passed as Source.
          </remark>
          <p>TDragObject is the ancestor of an whole tree of dragging objects, with the main branches supporting either drag-drop or drag-dock operations.
            The type of the operation is determined from the <link id="TControl.DragKind"/> property of the source control.</p>
          <remark>In contrast to the Delphi implementation, Lazarus has moved a couple of methods into the drag performers, so that these are no more available for customization.</remark>
          <p>A Lazarus DragObject mainly supplies the cursor and images, used in visual user feedback.
            Drag-drop operations typically signal acceptance of an possible drop by variations of the mouse cursor, and optionally can attach to it shapes of the dragged object(s).
            Drag-dock operations instead show a docking rectangle, that snaps to possible target locations when the mouse moves over docksites.</p>

          </p>
          <code>Left, Top, Right, Bottom: integer;
        minimum space left to the autosized control.
        For example: Control A lies left of control B.
        A has borderspacing Right=10 and B has borderspacing Left=5.
        Then A and B will have a minimum space of 10 between.

    Around: integer;
        same as Left, Top, Right and Bottom all at once. This will be added to
        the effective Left, Top, Right and Bottom.
        Example: Left=3 and Around=5 results in a minimum spacing to the left
        of 8.

    InnerBorder: integer;
        This is added to the preferred size.
        For example: A buttons widget returns 75x25 on GetPreferredSize.
        CalculatePreferredSize adds 2 times the InnerBorder to the width and
        height.
        
    CellAlignHorizontal, CellAlignVertical: TControlCellAlign;
        Used for example when the Parents.ChildSizing.Layout defines a table
        layout.

        <descr>
          <pre>TAnchorSide

    Class holding the reference sides of the anchors of a TControl.
    Every TControl has four AnchorSides:
    AnchorSide[akLeft], AnchorSide[akRight], AnchorSide[akTop] and
    AnchorSide[akBottom].
    Normally if Anchors contain akLeft, and the Parent is resized, the LCL
    tries to keep the distance between the left side of the control and the
    right side of its parent client area.
    With AnchorSide[akLeft] you can define a different reference side. The
    kept distance is defined by the BorderSpacing.
    
    Example1:
       +-----+  +-----+
       |  B  |  |  C  |
       |     |  +-----+
       +-----+

      If you want to have the top of B the same as the top of C use
        B.AnchorSide[akTop].Side:=asrTop;
        B.AnchorSide[akTop].Control:=C;
      If you want to keep a distance of 10 pixels between B and C use
        B.BorderSpacing.Right:=10;
        B.AnchorSide[akRight].Side:=asrLeft;
        B.AnchorSide[akRight].Control:=C;

      Do not setup in both directions, because this will create a circle, and
      circles are not allowed.
      
    Example2:
            +-------+
      +---+ |       |
      | A | |   B   |
      +---+ |       |
            +-------+
            
      Centering A relative to B:
        A.AnchorSide[akTop].Side:=asrCenter;
        A.AnchorSide[akTop].Control:=B;
      Or use this. It's equivalent:
        A.AnchorSide[akBottom].Side:=asrCenter;
        A.AnchorSide[akBottom].Control:=B;

        <descr>
          <p>Every TControl has a TLazAccessibleObject instace associated with it, which means that every TControl is potentially accessible, but to actually be usable the accessible object needs to have its properties set, the most important of which are the role, description and value. Native windowed classes should already receive accessibility properties from the underlying widgetset utilized, while TCustomControl descendents will have their accessibility taken care by the LCL itself. User applications should add accessibility for their own TCustomControl descendent classes and also possibly customize the descriptions of some elements. It is also possible to make an accessible object invisible for user, which is done by setting its AccessibleRole property to larIgnored.</p>

          </p>
          <p>SetBounds updates the BaseBounds and BaseParentClientSize, which are used by anchoring to keep the distance.
            For example loading a Form with TMemo and the lfm contains TMemo's Left and Width, then SetBounds is called two times for the memo.
          </p>
          <p>When the user maximizes a window, SetBounds is called for the form, but not for the Memo, keeping the BaseBounds of the Memo.
            If the Memo is anchored to the right, the Width of the Memo is changed based on the BaseBounds and BaseParentClientSize.

        <descr>
          <p>This event is triggered after the Width, Height, ClientWidth or ClientHeight of the control has changed.
            During autosize the size can change multiple times, but only the last change triggers the OnResize.
          </p>
          <p>Use OnResize to react on size changes.
            To also react on moves, use the OnChangeBounds event.
          </p>
          <p>If you want to customize the resize behaviour, use OnConstrainedResize instead.
          </p>
          <p>Common mistake:
            Keep in mind that ClientWidth and ClientHeight can change even when Width, Height stays the same.
            For example when the theme changes, the Width and Height remain the same, but the changed frame reduces the ClientWidth and ClientHeight.
            This does not happen that often under Windows, but it happens quite often on other platforms.
          </p>
          <p>Especially it is not sufficient to write only a TForm.OnResize handler to resize all controls on the form. This is a common bug in Delphi applications.

          <p>This is the character string, shown in controls with visible text content (<link id="#lcl.StdCtrls.TEdit">TEdit</link>...).</p>
          <remark>BEWARE: In other controls it can be the Name or Caption of the control, quite tricky to use.</remark>
          <p>The Delphi VCL implementation stores Text mostly in the widgets,
            using the virtual <var>Get/SetTextBuf</var> methods to exchange text between widgets and VCL.
            This means a lot of text copies and message handling in WM_GETTEXT and WM_SETTEXT.
          </p>
          <p>The LCL instead (typically) stores Text in a field of the control,
            and transfers it from/to the widgets only when required.
          </p>
          <p>To maintain VCL compatibility,
            the virtual <var>RealGet/SetText</var> methods have been introduced,
            which read or write the Caption string directly.
          </p>
          <p>The default <var>Get/SetTextBuf</var> implementation calls the <var>RealGet/SetText</var> methods,
            resulting in a string-to-PCHAR and another PCHAR-to-string conversion.
            But as long as <var>Get/SetTextBuf</var> is not overridden,
            <var>Get/SetText</var> can (and does) safely call <var>RealGet/SetText</var> immediately,
            to avoid beforementioned conversions.
          </p>
          <p>To keep things optimal, LCL components should always override RealGet/SetText;
            Get/SetTextBuf is only kept for compatibility.

          <code>{ LeftRightSpacing, TopBottomSpacing: integer;
        minimum space between client border and nearest child control.
        For example: ClientLeftRight=5 means leftmost child's Left position is at least 5.

    HorizontalSpacing, VerticalSpacing: integer;
        minimum space between each child control.
  }

  {   Defines how child controls are resized/aligned.

      cesAnchorAligning, cssAnchorAligning
        Anchors and Align work like Delphi. For example if Anchors property of
        the control is [akLeft], it means fixed distance between left border of
        parent's client area. [akRight] means fixed distance between right
        border of the control and the right border of the parent's client area.
        When the parent is resized the child is moved to keep the distance.
        [akLeft,akRight] means fixed distance to left border and fixed distance
        to right border. When the parent is resized, the controls width is
        changed (resized) to keep the left and right distance.
        Same for akTop,akBottom.

        Align=alLeft for a control means set Left leftmost, Top topmost and
        maximize Height. The width is kept, if akRight is not set. If akRight
        is set in the Anchors property, then the right distance is kept and
        the control's width is resized.
        If there several controls with Align=alLeft, they will not overlapp and
        be put side by side.
        Same for alRight, alTop, alBottom. (Always expand 3 sides).

        Align=alClient. The control will fill the whole remaining space.
        Setting two children to Align=alClient does only make sense, if you set
        maximum Constraints.

        Order: First all alTop children are resized, then alBottom, then alLeft,
        then alRight and finally alClient.

      cesScaleChilds, cssScaleChilds
        Scale children, keep space between them fixed.
        Children are resized to their normal/advised size. If there is some space
        left in the client area of the parent, then the children are scaled to
        fill the space. You can set maximum Constraints. Then the other children
        are scaled more.
        For example: 3 child controls A, B, C with A.Width=10, B.Width=20 and
        C.Width=30 (total=60). If the Parent's client area has a ClientWidth of
        120, then the children are scaled with Factor 2.
        If B has a maximum constraint width of 30, then first the children will be
        scaled with 1.5 (A.Width=15, B.Width=30, C.Width=45). Then A and C
        (15+45=60 and 30 pixel space left) will be scaled by 1.5 again, to a
        final result of: A.Width=23, B.Width=30, C.Width=67 (23+30+67=120).

      cesHomogenousChildGrowth, cssHomogenousChildDecrease
        Enlarge children equally.
        Children are resized to their normal/advised size. If there is some space
        left in the client area of the parent, then the remaining space is
        distributed equally to each child.
        For example: 3 child controls A, B, C with A.Width=10, B.Width=20 and
        C.Width=30 (total=60). If the Parent's client area has a ClientWidth of
        120, then 60/3=20 is added to each Child.
        If B has a maximum constraint width of 30, then first 10 is added to
        all children (A.Width=20, B.Width=30, C.Width=40). Then A and C
        (20+40=60 and 30 pixel space left) will get 30/2=15 additional,
        resulting in: A.Width=35, B.Width=30, C.Width=55 (35+30+55=120).

      cesHomogenousSpaceGrowth
        Enlarge space between children equally.
        Children are resized to their normal/advised size. If there is some space
        left in the client area of the parent, then the space between the children
        is expanded.
        For example: 3 child controls A, B, C with A.Width=10, B.Width=20 and
        C.Width=30 (total=60). If the Parent's client area has a ClientWidth of
        120, then there will be 60/2=30 space between A and B and between
        B and C.

          <p>Changing the ClientRect here, to the most probable size, reduces unneccessary resizes.
          </p>
          <p>Normally the clientwidth/clientheight is adjusted automatically by the widget,
            but it is up to widget when this will be done.
            The gtk for example just puts resize requests into a queue.
            The LCL would resize the child components just after this procedure due to the clientrect.
            On complex forms with lots of nested controls, this would result in thousands of resizes.

        <descr>
          <p>Calls the inherited method to calculate the default/preferred width and height for a <var>TWinControl</var>, which is used by the LCL autosizing algorithms as default size.
            Only positive values are valid. Negative or 0 are treated as undefined and the LCL uses other sizes instead.</p>

            <li>If this value can not be computed (e.g. the children depend too much on their
              parent clientrect), then the interface is asked for the preferred size</li>

          <p>For example the preferred size of a <var>TButton</var> is the size, where the label fits
            exactly. This depends heavily on the current theme and widgetset.</p>

            <var>TRadioButton</var> has a minimum size. But for stacking multiple TRadioButtons there should be some space around.
            This space is theme dependent, so it is passed as a parameter to the widgetset. </p>

      <element name="TWinControl.DoubleBuffered">
        <short>Allows to reduce flicker in the painting of the control.</short>
        <descr>
          <p>Paint requests typically are buffered in the message queue.
            When a paint message arrives, all elements of the control are drawn onto the screen,
            according to their type, style, state and content.
          </p>
          <p>This can cause flicker, when stacked controls wipe out preceding paintings,
            e.g. when unchanged text is erased from the screen before it is painted again,
            when it takes some time to retrieve the text of list entries,
            or wrapping long text at the current control boundaries.
            Owner-drawing also can cause noticeable flicker.
          </p>
          <p>To reduce such flicker, DoubleBuffered controls use a buffer bitmap
            into which all painting is redirected.
            When the bitmap has been updated, a paint request is queued for the control.
            When that paint request is received again,
            the prepared bitmap is output in one fast BitBlt transfer, eliminating any flicker.
          </p>
          <p>All this happens automatically, when DoubleBuffered is set to True,
            no further changes are required in application or custom control code.

        <short>A docking manager for tree-style layouts.</short>
        <descr>
          <p>A tree-style layout is organized in layers of a specific (horizontal or vertical) orientation.
            Every node in the tree is either a container for other nodes,
            or represents a zone with a single docked control.
            All child zones of an node have the same DockOrientation.
          </p>
          <p>The following documentation is copied from the Controls unit.
            It is of historical interest only, since it effectively describes the AnchorDocking,
            implemented in TCustomAnchoredDockManager.
            AnchorDocking is not related to visual drag-dock procedures,
            it merely is an attempt to implement just an layout manager.
          <br/>[todo: make this description an topic]
          </p>
          <remark>The TLazDockTree implementation never was finished,
            due to problems with the anchor "docking" mechanism.
            Use the EasyDockManager (examples/dockmanager) instead.</remark>
          <pre>This is an abstract class. A real implementation is e.g. in ldocktree.pas.

    Docking means here: Combining several windows to one. A window can here be
    a TCustomForm or a floating control (undocked) or a TDockForm.
    A window can be docked to another to the left, right, top, bottom or "into".
    The docking source window will be resized, to fit to the docking target
    window.

    Example1: Docking "A" (source window) left to "B" (target window)
    
       +---+    +----+
       | A | -&gt; | B  |
       +---+    |    |
                +----+
      Result: A new docktree will be created. Height of "A" will be resized to
              the height of "B".
              A splitter will be inserted between "A" and "B".
              And all three are children of the newly created TLazDockForm of the
              newly created TDockTree.
      
       +------------+
       |+---+|+----+|
       || A ||| B  ||
       ||   |||    ||
       |+---+|+----+|
       +------------+

      If "A" or "B" were floating controls, the floating dock sites are freed.
      If "A" or "B" were forms, their decorations (title bars and borders) are
      replaced by docked decorations.
      If "A" had a TDockTree, it is freed and its child dockzones are merged to
      the docktree of "B". Analog for docking "C" left to "A":
      
       +------------------+
       |+---+|+---+|+----+|
       || C ||| A ||| B  ||
       ||   |||   |||    ||
       |+---+|+---+|+----+|
       +------------------+
       

      
    Example2: Docking A into B
                +-----+
       +---+    |     |
       | A | ---+-&gt; B |
       +---+    |     |
                +-----+

      Result: A new docktree will be created. "A" will be resized to the size
              of "B". Both will be put into a TLazDockPages control which is the
              child of the newly created TDockTree.
              
       +-------+
       |[B][A] |
       |+-----+|
       ||     ||
       || A   ||
       ||     ||
       |+-----+|
       +-------+

    Every DockZone has siblings and children. Siblings can either be
    - horizontally (left to right, splitter),
    - vertically (top to bottom, splitter)
    - or upon each other (as notebook pages).


    InsertControl - undock control and dock it into the dock site. For example
                    dock Form1 left to a Form2:
                    InsertControl(Form1,alLeft,Form2);
                    To dock "into", into a TDockPage, use Align=alCustom.
    PositionDockRect - calculates where a control would be placed, if it would
                       be docked via InsertControl.
    RemoveControl - removes a control from the dock site.

          <p>InsertControl determines the layout and appearance of the just docked control, forcing a repaint of the container control if necessary.</p>
          <p>When SetReplacingControl has been called with a non-Nil Control before, the dropped control only should replace that control.</p>
          <p>A tree docking manager organizes the docksite into layers of horizontol or vertical orientation.
            As long as no more than one control is docked into a docksite, the tree has no orientation at all.
            The second docked control determines the orientation of the docksite and the dock tree.
            All further drops are either isogonal (in direction of the zone orientation) or orthogonal (opposite to the zone orientation).
            On an isogonal drop a new leaf zone is created for the dropped control, as a sibling of the already existing child zones.
            On an orthogonal drop the zone containing the DropControl becomes the root of another subtree, whose initial members are the leaf zones for Control and DropCtl.</p>
          <p>One value of InsertAt (alCustom) is reserved for notebook docking, where DropCtl is replaced by a tabbed notebook, and Control and DropCtl are moved into pages of the notebook.
            The notebook is a docksite of its own, further drops into the notebook are handled by the notebook itself, the DockManager of the host docksite is not involved.</p>

          <var>AutoSize</var> - boolean property that permits the size of a control to be adjusted automatically</short>
        <descr>
          <p>[deverses an review!!!]
            <var>AutoSize</var> is a boolean property found in many classes; it permits the size of a control to be adjusted automatically to accommodate differences in the text or graphic contained therein, and allows most efficient use of available space</p>
          <p>Many controls call  <link id="#lcl.Controls.TControl.DoAutoSize">TControl.DoAutoSize</link> to perform the actual auto-sizing. </p>
          <p>IMPORTANT: Many Delphi controls override this method and many call this method directly after setting some properties.</p>
          <p>During handle creation not all interfaces can create complete Device Contexts which are needed to calculate things like text size.</p>
          <p>That's why you should always call <link id="#lcl.Controls.TControl.AdjustSize">AdjustSize</link> instead of <var>DoAutoSize</var>.</p>
          <p>
            <var>TControl.AdjustSize</var> calls 
            
            
            <var>DoAutoSize</var> in a smart fashion.</p>
          <p>During loading and handle creation the calls are delayed.</p>
          <p>This method initially does the same as <link id="#lcl.Controls.TWinControl.DoAutoSize">TWinControl.DoAutoSize</link>.  But since <var>DoAutoSize</var> is commonly overriden by descendant components,  it is not useful to perform all tests, which can result in too much overhead. To reduce this the LCL calls <var>AdjustSize</var> instead.</p>
          <p>When setting <var>AutoSize</var> = true the LCL autosizes the control in width and height. This is one of the most complex parts of the LCL, because the result depends on nearly a hundred properties. Let's start simple:</p>
          <p>The LCL will only autosize the Width or Height if it is free to resize. In other words - the width is not autosized if:</p>
          <ul>
            <li>the left and right side is anchored. You can anchor the sides with the <var>Anchors</var> property or by setting the <var>Align</var> property to <var>alTop</var>, <var>alBottom</var> or <var>alClient</var>
            </li>
            <li>the Width and Height are bound by the <var>Constraints</var> properties. The Contraints can also be overriden by the widgetset. For example the winapi does not allow resizing the height of a combobox. And the gtk widgetset does not allow resizing the width of a vertical scrollbar</li>
          </ul>
          <p>The new size is calculated by the protected method <link id="#lcl.Controls.TControl.CalculatePreferredSize">TControl.CalculatePreferredSize</link>.
            This method asks the widgetset for an appropriate Width and Height. For example a <var>TButton</var> has preferred Width and Height. A <var>TComboBox</var> has only a preferred Height. The preferred Width is returned as 0 and so the LCL does not autosize the Width - it keeps the width unaltered. Finally a <var>TMemo</var> has no preferred Width or Height. Therefore AutoSize has no effect on a TMemo.</p>
          <p>Some controls override this method. For example the <var>TGraphicControl</var> descendants like <var>TLabel</var> have no window handle and so cannot query the widgetset. They must calculate their preferred Width and Height themselves.</p>
          <p>The widgetsets must override the <var>GetPreferredSize</var> method for each widget class that has a preferred size (Width or Height or both).</p>
          <p>
            <b>Parent.AutoSize</b>
          </p>
          <p>The above described the simple explanation. The real algorithm provides far more possibilities and is therefore far more complex.</p>
          <p>
            <b>Properties / Methods</b>
          </p>
          <ul>
            <li>Left</li>
            <li>Top</li>
          </ul>
          <p>If <var>Parent</var> is not nil then <var>Left, Top</var> are the pixel distance to the top, left pixel of the parent's client area (not scrolled). Remember the client area is always without the frame and scrollbars of the parent. For Delphi users: Some VCL controls like TGroupbox define the client area as the whole control including the frame and some not - the LCL is more consistent, and therefore Delphi incompatible. Left and Top can be negative or bigger than the client area. Some widgetsets define a minimum/maximum somewhere around 10.000 or more.</p>
          <p>When the client area is scrolled the Left and Top are kept unchanged. </p>
          <p>During resizing/moving Left and Top are not always in sync with the coordinates of the Handle object.</p>
          <p>If Parent=nil then Left, Top depend on the widgetset and the window manager. Till Lazarus 0.9.25 this is typically the screen coordinate of the left,top of the client area of the form. This is Delphi incompatible. It is planned to change this to the Left, Top of the window.</p>
          <p>Hint:</p>
          <p>Each time you change Left and Top the LCL moves instantly. If you want to change both Left and Top use instead:</p>
          <code>with Button1 do
    SetBounds(NewLeft,NewTop,Width,Height);
          </code>
          <ul>
            <li>Width</li>
            <li>Height</li>
          </ul>
          <p>The Size in pixels must not be negative, and most widgetsets do not allow Width=0 and/or Height=0. Some controls on some platforms define a bigger minimum constraint. Instead of sizing a control to Width=0 and/or Height=0, set Visible=false. During resizing/moving Width and Height are not always in sync with the size of the Handle object.</p>
          <ul>
            <li>BoundsRect</li>
          </ul>
          <p>Same as Bounds(Left,Top,Width,Height).</p>
          <p>Common newbie mistake:</p>
          <code>BoundsRect.Left:=3; // WRONG: common newbie mistake
</code>
          <p>This has no effect, because reading BoundsRect is a function. It creates a temporary TRect on the stack.</p>
          <ul>
            <li>ClientRect</li>
          </ul>
          <p>Left and Top are always 0,0. Width and Height are the visible size in pixels of the client area. Remember the client area is without the frame and without scrollbars. In a scrollable client area the logical client area can be bigger than the visible.</p>
          <ul>
            <li>ClientOrigin</li>
          </ul>
          <p>Returns the screen coordinate of the top left coordinate 0,0 of the client area. Note that this value is the position as stored in the interface and is not always in sync with the LCL. When a control is moved, the LCL sets the bounds to the desired position and sends a move message to the interface. It is up to the interface to handle moves instantly or queued.</p>
          <ul>
            <li>LCLIntf.GetClientBounds</li>
          </ul>
          <p>Returns the client bounds of a control. Like ClientRect, but Left and Top are the pixel distances to the control's left, top. For example on a TGroupBox the Left, Top are the width and height of the left and top frame border. Scrolling has no effect on GetClientBounds.</p>
          <ul>
            <li>LCLIntf.GetWindowRect</li>
          </ul>
          <p>After the call, ARect will be the control area in screen coordinates. That means, Left and Top will be the screen coordinate of the TopLeft pixel of the Handle object and Right and Bottom will be the screen coordinate of the BottomRight pixel.</p>
          <ul>
            <li>FBaseBoundsLock: integer</li>
          </ul>
          <p>Increased/Decreased by LockBaseBounds/UnlockBaseBounds.
            Used to keep FBaseBounds during SetBounds calls.</p>
          <ul>
            <li>FBaseParentClientSize: TPoint</li>
          </ul>
          <p>The Parent.ClientRect size valid for the FBaseBounds.
            FBaseBounds and FBaseParentClientSize are used to calculate the distance for
            akRight (akBottom).
            When the parent is resized, the LCL knows what distance to keep.</p>
          <ul>
            <li>FBoundsRectForNewParent: TRect</li>
          </ul>
          <p>When changing the Parent of a control the Handle is recreated and many
            things can happen. Especially for docking forms the process is too
            unreliable. Therefore the BoundsRect is saved. The VCL uses a similar
            mechanism.</p>
          <ul>
            <li>FLastDoChangeBounds: TRect</li>
          </ul>
          <p>Used to avoid calling OnChangeBounds with the same coordinates. This reduces
            user defined autosizing.</p>
          <ul>
            <li>FLastResizeClientHeight: integer</li>
            <li>FLastResizeClientWidth: integer</li>
            <li>FLastResizeHeight: integer</li>
            <li>FLastResizeWidth: integer</li>
          </ul>
          <p>Used to avoid calling OnResize with the same coordinates. This reduces user
            defined autosizing.</p>
          <ul>
            <li>FLoadedClientSize: TPoint</li>
          </ul>
          <p>During loading many things are delayed and many things are set and worse: in
            the wrong order. That's why SetClientWidth/SetClientHeight calls are stored
            and set at end of loading again.
            This way the LCL can restore the distances (e.g. akRight) used during
            designing.</p>
          <ul>
            <li>FReadBounds: TRect</li>
          </ul>
          <p>Same as FLoadedClientSize, but for SetLeft, SetTop, SetWidth, SetHeight.</p>
          <ul>
            <li>procedure SetBoundsRectForNewParent(const AValue: TRect);</li>
          </ul>
          <p>Used to set FBoundsRectForNewParent. See above.</p>

          </ul>
          <p>A smart version of SetBounds, reducing overhead during creation and loading.</p>
          <ul>
            <li>procedure UpdateBaseBounds(StoreBounds, StoreParentClientSize, UseLoadedValues: boolean); virtual;</li>
          </ul>

            <li>procedure SetClientWidth(Value: Integer);  </li>
          </ul>
          <p>Exists for Delphi compatibility too. Resizes the control, to get the wanted ClientRect size.</p>
          <ul>
            <li>procedure ChangeBounds(ALeft, ATop, AWidth, AHeight: integer); virtual;</li>
          </ul>
          <p>This is the internal SetBounds.
            Applies constraints, updates base bounds, calls OnChangeBound, OnResize,
            locks bounds.</p>
          <ul>
            <li>procedure DoSetBounds(ALeft, ATop, AWidth, AHeight: integer); virtual;</li>
          </ul>
          <p>This really sets the FLeft, FTop, FWidth, FHeight private variables.</p>
          <ul>
            <li>procedure SetBounds(aLeft, aTop, aWidth, aHeight: integer); virtual;</li>
          </ul>
          <p>This is the standard procedure overriden by many Delphi controls. TWinControl overrides it too. </p>
          <p>Ignores calls when bounds are locked; lock the FBoundsRealized to avoid overhead to the interface during auto sizing.</p>
          <p>ChangeBounds is not locked this way.</p>

          <ul>
            <li>function GetClientScrollOffset: TPoint; virtual;</li>

            Note that this value is the position as stored in the interface and is not always in sync with the LCL.
            When a control is moved, the LCL sets the bounds to the wanted position

          <p>Every control has an origin (Top, Left) and extent (Width, Height). The origin is relative to its Parent control (client coordinates) or,

          <p>The ClientRect describes the internal (client) area of a container control (TWinControl), excluding borders. Its Top and Left are always zero.
            In a TScrollingWinControl...</p>
          <p>BaseBounds holds the designed Bounds, to be used e.g. when a scale factor is set later.</p>
          <p>GetControlOrigin returns the origin in screen coordinates. These values are not always in sync with the true screen position, managed by the widgetset.</p>

      <topic name="Anchoring Controls">
        <short>How multiple controls can be aligned and resized together, at runtime.</short>
        <descr>
          <p>The tree-style layout of a form allows to specify table-style areas,
            with a common width or height of all controls in the same area (using container controls like e.g. TPanel).
          </p>
          <p>Delphi introduced control anchoring to the sides of the Parent control.
            This means when a control in a form has Anchors[akRight]=True,
            its right side keeps its distance from the right side of its Parent,
            when its Parent is resized.
          </p>
          <p>The default anchors [akLeft,akTop] keep every control anchored to the origin (TopLeft) of their Parent control (of form).
            This will cause controls to disappear when the form is shrinked,
            or the user has to scroll through the form's client area.
          </p>
          <p>When a control shall e.g. use the available space, left over to its right,
            Anchors=[akLeft,akRight] will result in a variable-width control.
          </p>
          <p>The Align property allows to stack controls at their Parent's sides,
            e.g. all controls with Align=alTop are stacked at the top of their Parent.
            The remaining space in the Parent can be occupied by a single control,
            of Align=alClient.
          </p>
          <p>Both Anchors and Align are tightly coupled, changing one property will affect the other one.
            This is harmless in so far, as the IDE (form designer) keeps all adjustments in sync, free of conflicts.
          </p>
          <p>Some people found this approved layout method too restrictive, and too complicated to use,
            and now LCL controls <b>also</b> can be anchored <b>freely</b> to each other.
            This layout management is traditionally referred to as "Anchor Docking", even if it is not related to docking at all.
          </p>
          <remark>This freedom requires that the GUI designer is responsible for consistent anchor specifications,
            which do not result in unresolvable cyclic references or other contradictions.
          </remark>
          <p>Anchor docking allows to anchor every side of a control to an arbitrary side of another control,
            i.e. the left side of an Edit control can be anchored to the right side of its associated Label.
          </p>
          <code>Example1
    --------
      If you want to have the top of B the same as the top of C:
       +-----+  +-----+
       |  B  |  |  C  |
       |     |  +-----+
       +-----+
      use
        B.AnchorSide[akTop].Control:=C;
        B.AnchorSide[akTop].Side:=asrTop;
          </code>
          <p>When you want to have a gap between both controls,
            set e.g. B.Borderspacing.Right to the desired amount.
            Setting C.Borderspacing.Left will have the same effect, and both can be used together;
            the resulting gap then reflects the maximum value of both properties.
          </p>
          <p>BorderSpacing is in effect even for controls without special anchoring,
            when AutoSize is used.
          </p>
          <p>Anchor docking also allows to center a control relative to another control.
          </p>
          <code>Example2
    --------
      For centering A relative to B:
            +-------+
      +---+ |       |
      | A | |   B   |
      +---+ |       |
            +-------+
      use
        A.AnchorSide[akTop].Side:=asrCenter;
        A.AnchorSide[akTop].Control:=B;
      Or use this, it's equivalent:
        A.AnchorSide[akBottom].Side:=asrCenter;
        A.AnchorSide[akBottom].Control:=B;
          </code>
          <p>TControlChildSizing and TControlChildrenLayout offers additional means for aligning and separating controls.
