Interfaces

GtkCTree implements AtkImplementorIface and GtkBuildable.

Detailed Description

The GtkCTree widget is used for showing a hierarchical tree to the user, for example a directory tree. The tree is internally represented as a set of GtkCTreeNode structures. The interface has much in common with the GtkCList widget: rows (nodes) can be selected by the user etc. Positions in the tree are often indicated by two arguments, a parent and a sibling, both GtkCTreeNode pointers. If the parent is NULL, the position is at the root of the tree and if the sibling is NULL, it will be the last child of parent, otherwise it will be inserted just before the sibling. GtkCTree has been deprecated since GTK+ 2.0 and should not be used in newly written code. Use GtkTreeView instead.

Structures

GtkCTree
WARNING: GtkCTree is deprecated and should not be used in newly-written code. The GtkCTree contains the following user-accessible fields. These fields should be considered read-only; to set the values, use the methods below.
integer tree_indent ;
The number of pixels each successive level of the tree is indented in the display.
integer tree_spacing ;
The space in pixels between the graphical tree and the text in the node.
integer tree_column ;
The index of the column for which the tree graphics is drawn.
GtkCTreeLineStyle line_style ;
The style in which the lines in the tree graphics are drawn.
GtkCTreeExpanderStyle expander_style ;
The style in which the expander buttons are drawn.
GtkCTreeExpanderStyle expander_style ;
FIXME.
GtkCTreeRow
WARNING: GtkCTreeRow is deprecated and should not be used in newly-written code. A structure representing a single row in the tree graph. The values inside the structure should be considered read-only. This structure is derived from the GtkCListRow structure.
GtkCTreeNode * parent ;
The parent node of the node corresponding to this row.
GtkCTreeNode * sibling ;
The next sibling node of the node corresponding to this row.
GtkCTreeNode * children ;
The first child node corresponding to this row; to access the other children, just use the siblings of that node.
GdkPixmap * pixmap_closed ;
The pixmap to be shown when the node is collapsed.
GdkBitmap * mask_closed ;
The mask for the above pixmap.
GdkPixmap * pixmap_opened ;
The pixmap to be shown when the node is expanded.
GdkBitmap * mask_opened ;
The mask for the above pixmap.
integer level ;
The level of this node in the tree.
numeric is_leaf : 1;
Whether this row is a leaf.
numeric expanded : 1;
Whether the children of this row are visible.
GtkCTreeNode
WARNING: GtkCTreeNode is deprecated and should not be used in newly-written code. This structure is opaque - you should use the functions GTK_CTREE_ROW, GTK_CTREE_NODE_NEXT etc. as well as the functions below to access it.

Convenient Construction

gtkCTree is the result of collapsing the constructors of GtkCTree (gtkCTreeNewWithTitles, gtkCTreeNew) and accepts a subset of its arguments matching the required arguments of one of its delegate constructors.
