TreeSelect (Function)

In french: ArbreSelect

Returns the full path of the selected element in a TreeView control.

Example of TreeView control:

Note: The TreeSelect function can be used on both:

a TreeView control populated programmatically, based on a data file, or based on a variable.
a single-selection or multi-selection TreeView control. For multi-selection TreeView controls, TreeSelect must be used in a loop in order to get all selected rows.

Example

// Chemin complet de l'élément sélectionné dans le champ Arbre "ARBRE_RecetteTV"
ResChemin = TreeSelect(ARBRE_RecetteTV)

// Lignes sélectionnées dans un champ Arbre par programmation multisélection
FOR i = 1 _TO_ TreeSelectCount(ARBRE_ARBRE1)
	Trace("Elément sélectionné : " + TreeSelect(ARBRE_ARBRE1, False, i))
END
// Équivalent à :
// i est un entier
// POUR TOUTE LIGNE SELECTIONNEE i DE ARBRE_ARBRE1
// 	Trace("Elément sélectionné : " + ArbreSelect(ARBRE_ARBRE1, Faux, i-1))
// FIN
