Hi, I have an XmList (actually a ScrolledList) inside a RowColumn widget.
The visible item count of the list is configured at widget creation time. When the RowColumn widget is resized, I would like to adapt that visible item count to the new size of the parent widget. Is there an easy way to do this? What I have come up with so far in theroy is to do the following: Listen to the resize event of the RowColumn widget, recompute the visible line count in a callback and then set it explicitly using XtSetValues(XmNvisibleItemCount). Unfortunately, I have not found any callback resource in the RowColumn widget. How can I listen to resize events of a widget? Best, Holger
