I am using TTMSFNCPanel aligned at the bottom of the application to hide/show a GUI section,
Consequently, the pbExpander and pbDropDown looks for the Header button are inverted.
I'd like to get the down arrow when expanded and Up arrow when collapsed.

Is there an easy way to get this behaviour without subclassing the complete control ?


The expand/collapse arrow is pointing in the direction it is going after executing the action. This is by design. It's currently not possible to change this without subclassing. We have added this on our request list.
