- Node to expand
- Selection bar
<TreeView>.ExpandAll (Function) In french: <Arbre>.DérouleTout Expands a node and all its child elements in a TreeView control. Example of TreeView control:
Reminder: At runtime, a node is expanded when the node name is preceded by "-". // Expand the "Desserts" node in the "TREE_TVRecipe" TreeView control
// All child elements are also expanded
Res = TREE_TVRecipe.ExpandAll("Recipes" + TAB + "Desserts")
Syntax
<Result> = <TreeView control>.ExpandAll([<Node to expand>])
<Result>: Boolean - True if the node and its child elements have been expanded,
- False otherwise.
<TreeView control>: Control name Name of the TreeView control to be used. <Node to expand>: Optional character string Path of the node to expand (as well as its child elements). This parameter has the following format:
"<Root name>" + TAB + ["<Name of 1st node>" + TAB + ...
["<Name of 2nd node>" + TAB + [...]]]"<Leaf name>" If this parameter is not specified, the TreeView control is expanded from the root. 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). Remarks Node to expand If the node to expand: - is not found, <TreeView>.ExpandAll returns False.
- is not specified, <TreeView>.ExpandAll returns True and the TreeView control is expanded from its root.
- is a leaf, <TreeView>.ExpandAll returns True.
- is already expanded, <TreeView>.ExpandAll returns True, and the child elements are expanded if necessary.
- is not visible, <TreeView>.ExpandAll makes this node visible. Its "parent" and "sibling" elements are also displayed. The "parent" elements are expanded.
When <TreeView>.ExpandAll is called, if the specified branch and/or one of its children have a procedure associated via the AddChildDelayed property, this procedure will be executed. Selection bar <TreeView>.ExpandAll does not change the position of the selection bar.
