Package: Ctree

Description

package Gtk.Ctree is

This widget is deprecated. Use Gtk.Tree_View instead.

This widget is similar to Gtk_Clist but it displays a tree with expandable nodes instead of a simple list. Gtk_Tree is a more flexible tree widget (it can have arbitrary widgets in the tree cells), but it is less efficient and is limited to 32768 pixels.

If you need horizontal or vertical scrolling, you mustn't put this widget in a Gtk_Viewport, and then in a Gtk_Scrolled_Window. Put it directly into a Gtk_Scrolled_Window, or horizontal scrolling will be disabled, and the column headers will disappear when scrolling vertically.

Binding from C File version 2.8.17

Get_Type

function Get_Type return Gtk.Gtk_Type;
Return the internal value associated with a Gtk_Ctree.

Mask_Opened: in Gdk.Bitmap.Gdk_Bitmap;
Is_Leaf: in Boolean;
Expanded: in Boolean) return Gtk_Ctree_Node;
Insert a new node in the Ctree. Parent is the parent node. If null, the new node is part of the root. The new node will be inserted right on top of Sibling. If Sibling is null, then it will be the first node in the subtree. Text contains the text for each cell of the node. Note that Insert_Node expects the length of the Text parameter to be equal to the number of columns of the Ctree. Spacing is the number of pixels between the lines of the tree and the text in the same column. If Is_Leaf is True, then the node won't contain any subtree. If False, the newly created node can be used as the Parent for further node creation. In this case, Expanded indicates whether the subtree associated with this node should be initially visible. In addition to the "+" or "-" sign indicating whether the subtree is expanded or not, it is possible to put a pixmap giving this information. Pixmap_Closed and Mask_Closed represent the image and the mask used when the subtree is closed; similarly, Pixmap_Opened and Mask_Opened represent the image and the mask used when the subtree is opened.
