How to hide a TopSeparatorFrame [message #14863]

How would one best hide and show a TopSeparatorFrame (or the other equivalents). I could make the TopSeparatorFrameClass public for one and add the methods. Is there another way which doesn't add extra public names? Anyway, those classes are visible in Assist++ so it shouldn't be a problem.

Since TopSeparatorFrame is just a CtrlFrame (no Ctrl inheritance) IMO it would be easiest just to use AddFrame (or InsertFrame) and RemoveFrame as necessary.

Yes, but CtrlFrame is an abstract class, so I can not declare a variable with this type and use it to store the value from TopSeparatorFrame().

Also the frame I want to hide is deep in a nest of layouts and other frames, and I don't know if Add/Remove method would maintain the "Z"-order.

It should work (I've done similar things before). If you've only got one TopSeparatorFrame:

	
...
		ctrl.AddFrame(ViewFrame());
		ctrl.AddFrame(TopSeparatorFrame());
		ctrl.AddFrame(ViewFrame());
...
	void RemoveSeparator()
	{
		framepos = ctrl.FindFrame(TopSeparatorFrame());
		ctrl.RemoveFrame(framepos);	
	}

        void AddSeparator()
	{
		ctrl.InsertFrame(framepos, TopSeparatorFrame());
	}

(framepos is a member variable, natch)

It'll be a bit more difficult if you've got more than one TopSeparatorFrame, but it should be possible with more specific information about the layout.

Indeed, it does work as expected. Tank you! Once again, you knowledge of the library is impressive.

Another question: menu items which never had a call to Check look like all other items, but ones that had a Check call, even with the false parameter have an empty check box icon. This is intentional, I suppose?
