Description

The function invalidate-pane-constraints informs the CAPI that the constraints (its minimum and maximum size) of pane may have changed. The CAPI then checks this, and if the pane is no longer within its constraints it resizes it so that it is and then makes the pane's parent layout lay its children out and display them again at their new positions and sizes. If the pane is resized, then invalidate-pane-constraints returns t.
