In french: <Arbre>.Déroule

Expands a node in a TreeView control. The "child" elements (nodes or leaves) of this node become visible.

Example of TreeView control:

Reminder: At run time, a node is expanded when the node name is preceded by "-".

Example

// Expand the "Desserts" node in the "TREE_RecipeTV" TreeView control
Res = TREE_RecipeTV.Expand("Recipes" + TAB + "Desserts")

Syntax

<Result> = <TreeView control>.Expand(<Node to expand>)

<Result>: Boolean

True if the node was expanded,
False otherwise.

<TreeView control>: Control name

Name of TreeView control to use.

<Node to expand>: Character string

Path of node to expand. This parameter has the following format:

"<Name of root>" + TAB + ["<Name of 1st node>" + TAB + ...
["<Name of 2nd node>" + TAB + [...]]]"<Leaf name>"

In case of duplicates on a path element, this path can contain the element identifier (specified at the end of its name by TreeID).
