## Class Description

     TGListView, TGLVContainer and TGLVEntry

     A list view is a widget that can contain a number of items
     arranged in a grid or list. The items can be represented either
     by a string or by an icon.

     The TGListView is user callable. The other classes are service
     classes of the list view.

     A list view can generate the following events:
     kC_CONTAINER, kCT_SELCHANGED, total items, selected items.
     kC_CONTAINER, kCT_ITEMCLICK, which button, location (y<<16|x).
     kC_CONTAINER, kCT_ITEMDBLCLICK, which button, location (y<<16|x).

TGListView(const TGWindow *p, UInt_t w, UInt_t h, UInt_t options, ULong_t back) : TGCanvas(p, w, h, options, back)

     Create a list view widget.

~TGListView()

     Delete a list view widget.

void SetHeaders(Int_t ncolumns)

     Set number of headers, i.e. columns that will be shown in detailed view.
     This method must be followed by exactly ncolumns SetHeader() calls,
     making sure that every header (i.e. idx) is set (for and example see
     SetDefaultHeaders()).

void SetHeader(const char *s, Int_t hmode, Int_t cmode, Int_t idx)

     Set header button idx [0-fNColumns>, hmode is the x text alignmode
     (ETextJustification) for the header text and cmode is the x text
     alignmode for the item text.

const char* GetHeader(Int_t idx) const

     Returns name of header idx. If illegal idx or header not set for idx
     0 is returned.

void SetDefaultHeaders()

     Default headers are: Name, Attributes, Size, Owner, Group, Modified.
     The default is good for file system items.

void SetViewMode(EListViewMode viewMode)

     Set list view mode.

void SetContainer(TGFrame *f)

     Set list view container. Container must be at least of type
     TGLVContainer.

void Layout()

     Layout list view components (container and contents of container).

Bool_t ProcessMessage(Long_t msg, Long_t parm1, Long_t parm2)

     Handle messages generated by the list view components.

void Clicked(TGLVEntry *entry, Int_t btn)

     Emit Clicked() signal.

void Clicked(TGLVEntry *entry, Int_t btn, Int_t x, Int_t y)

     Emit Clicked() signal.

void DoubleClicked(TGLVEntry *entry, Int_t btn)

     Emit DoubleClicked() signal.

void DoubleClicked(TGLVEntry *entry, Int_t btn, Int_t x, Int_t y)

     Emit DoubleClicked() signal.

FontStruct_t GetDefaultFontStruct()

const TGGC& GetDefaultGC()

void SavePrimitive(ofstream &out, Option_t *option)

     Save a list view widget as a C++ statement(s) on output stream out.
