Method XbpTreeView():itemFromPos()

Retrieves an item in the tree view from the mouse position.

:itemFromPos( <aPos> ) --> oTreeViewItem | NIL

<aPos> := { nX, nY }

The parameter <aPos> is a two element array holding numeric values for the X and Y coordinate. It is usually the position of the mouse pointer.

This method returns the XbpTreeviewItem object at the given position or NIL if there is no item at that position.

The method :itemFromPos() is mostly used to determine the XbpTreeviewItem that is clicked with the mouse pointer. In this case, the first message parameter of the AppEvent() function is passed for <aPos>.
