TreeStatus (Function)

In french: ArbreEtat

Returns the state of a node: wound, unwound or non-existent.

Example of TreeView control:

Example

// Etat du noeud "Desserts" dans le champ Arbre "ARBRE_RecetteTV"
ResEtat = TreeStatus(ARBRE_RecetteTV, "Recettes" + TAB + "Desserts")

Syntax

<Result> = TreeStatus(<TreeView control> , <Node>)

<Result>: Integer constant

Node status.
tvCollapse Collapsed node.
tvError Node not found.
tvExpand Expanded node.

<TreeView control>: Control name

Name of the TreeView control to be used.

<Node>: Character string

Path of node 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).

Remarks

A collapsed or expanded node can be visible or not

The status returned corresponds to the internal status of the element. An expanded element is not necessarily visible because one of its parents may be collapsed.

For example: If the node "Recipes" + TAB + "Desserts" is rolled up, the node "Recipes" + TAB + "Desserts" + TAB + "Ice cream" can be rolled up or unrolled.
