In VLF-ONE a filter or command handler can programmatically expand or shrink the pane it is in (avPaneMaximize, avPaneMinimize) and it can restore its pane back to its original size (avPaneRestore).

These methods are asynchronous – the request is queued up and waits for the command handler or filter that issued the instruction to finish its processing before the expand/shrink/maximize/restore is performed.

If a filter or command handler needs to maximize/minimize/restore a filter or command handler in a different pane, this can be done by signalling. The target command handler or filter listens for the signal and maximizes or minimizes or restores itself.
