TreeGetIndex (Function) In french: ArbreRécupèreIndice
 Warning
From version 28 (75), TreeGetSubscript is kept for backward compatibility. This function is replaced by TreeGetIndex.
Returns the index of an element (node or leaf) in a TreeView control. Remark: For example, this function gets an index to call the properties of a row in a TreeView control with the following syntax:
TreeView_control[Index].<Property Name> = ...
// Switch the leaf line to red
nIndex is int
nIndex = TreeGetIndex(TREE_TreeView1, "Root" + TAB + "Node" + TAB + "Leaf")
IF nIndex > 0 THEN
// Checks whether the node is visible before using it
IF TREE_TreeView1[nIndex] = -1 THEN
// The node is not visible: expand it to make it visible
TreeExpand(TREE_TreeView1, "Root" + TAB + "Node" + TAB + "Leaf")
END
// Modifies its color
TREE_TreeView1[nIndex].Color = DarkRed
END
Syntax
<Result> = TreeGetIndex(<TreeView control> , <Element path>)
<Result>: Integer - Index if the element was found.
Caution: The node can be handled only if it is visible (which means if it is expanded). - -1 if the element does not exist.
<TreeView control>: Control name Name of the TreeView control to be used. <Element path>: Character string Full path of element to use. This parameter has the following format:
"<Root name>" + TAB + ["<Name of 1st node>" + TAB + ...
["<Name of 2nd node>" + TAB + [...]]]"<Leaf name>"
If there are two elements with the same name in the path, you can add the IDs of the elements (after their names using TreeID).
