Set-workarea() may be called (e.g. from the Post-open property of Info Box objects) to specify that the window or dialog involved must resize itself when the end user drags the embedded Tree View or List View to a bigger/smaller size. To make this possible the Resize Child property must be set to Yes as well.
set-workarea( control )
The required control identifies the Tree View or List View control.
