Detailed Description

This class wraps gtkctree widget.

Signals

• select_node_signal, emitted on selecting a tree node (or double clicking on extended selection mode). SelectedNode property contains selected node address. SelectedNode is set to NULL if no node is selected.
• unselect_node_signal, emitted on unselecting a tree node . UnselectedNode property contains uelected node address. UnselectedNode is set to NULL if no node is unselected.

Tip

VDKTreeNode is defined as GtkCTreeNode*

EXAMPLES

On ./testvdk/ctreewin.cc

Destructor

Member Function Documentation

VDKCustomTree::__rproperty	(	VDKCustomTree	,
		int
	)

Sets/gets selected column, an answer == -1 means no column selected.

VDKCustomTree::__rproperty	(	VDKCustomTree	,
		int
	)

Sets/gets unselected column, an answer == -1 means no column unselected.

VDKCustomTree::__rwproperty	(	VDKCustomTree	,
		int
	)

Sets/gets spacing distance (default 5)

VDKCustomTree::__rwproperty	(	VDKCustomTree	,
		VDKTreeNode
	)

Sets/gets selected node, setting to NULL will select root node. An aswer NULL means no node selected.

VDKCustomTree::__rwproperty	(	VDKCustomTree	,
		VDKTreeNode
	)

Sets/gets unselected node, setting to NULL will unselect root node. An aswer NULL means no node unselected.

VDKCustomTree::__rwproperty	(	VDKCustomTree	,
		GtkCTreeLineStyle
	)

Sets/gets line style arg. (default GTK_CTREE_LINES_SOLID)

VDKCustomTree::__rwproperty	(	VDKCustomTree	,
		GtkCTreeExpanderStyle
	)

Sets/gets expander style (default GTK_CTREE_EXPANDER_SQUARE)

VDKTreeNode VDKCustomTree::AddNode	(	char *	text[],
		GtkCTreeNode *	parent,
		bool	expanded = true,
		bool	isLeaf = false,
		char **	pixmap_closed = NULL,
		char **	pixmap_opened = NULL
	)

Add a node to <parent> tree.

Parameters

text,an	array of strings
parent,if	NULL add the node as a new root (same as adding a row to a VDKCustomList)
isLeaf,if	is a leaf or not
pixmap_closed,pixmap	showed when node is collapsed
pixmap_open,pixmap	showed when node is expanded

void VDKCustomTree::Clear ( )

virtual

Clear widget

Reimplemented from VDKCustom.

VDKTreeNodeList * VDKCustomTree::Find

(

node

)

Returns true if <node> is expanded

Parameters

node

bool VDKCustomTree::IsLeaf

(

VDKTreeNode

node

)

Returns true if <node> is a leaf

Parameters

node

char * VDKCustomTree::Key

(

VDKTreeNode

node

)

Returns node key

Parameters

node

Tuple VDKCustomTree::operator[]

(

VDKTreeNode

node

)

Returns a tuple of <node> node, an array containing all columns texts.

Parameters

node

int VDKCustomTree::RemoveKey

(

char *

key

)

bool VDKCustomTree::RemoveNode

(

VDKTreeNode

node

)

Removes a node, return true on success

Parameters

node,node

to be removed

VDKTreeNode VDKCustomTree::Selection ( )

inline

Returns selected node

VDKTreeNodeArray & VDKCustomTree::Selections

(

)

Returns an array of selected nodes (valid on multiple and extended mode)

VDKTreeNode VDKCustomTree::Unselection ( )

inline

Returns unselected node
