Hello list denizens.
I've just created some UI with an NSDrawer attached to a regular
window. I've done this before a while back and everything worked
fine. I thought everything was fine this time too: the drawer opens
on command, has the correct initial size, and behaves mostly normally
except when I try to resize the main window (with the drawer open).
The main window resizes just fine, but leaves the drawer exactly where
is was (i.e. no effect on its size or position - i.e. because it is on
the RHS of the window, it is left as an island if the window is made
smaller horizontally, and covered up if the window is made bigger.
When the window is resized (for instance, leaving the drawer
isolated), it will move the drawer (as an island at a fixed offset)
around with it when subsequently moved. If you grab the draw to
resize it (i.e. pull it 'out' further by the right hand edge), it will
suddenly snap back to where it should be on the right side of the
window.
The NSDrawer appears to have everything it needs, but there most be
something internally preventing the parent window's resizing from
getting propagated (... or something).
I have no delegate set on the NSDrawer, only contentView and
parentView outlets are connected and working. I just want default
sizing behaviour, so don't have a need for the delegate notification
(and assume everything should default without it). I do have some
minimum size constraints set on the NSDrawer object (set in IB 3), and
these are reasonable and correctly adhered to when the drawer is
opened and used.
My Main Window is not (to my knowledge) special. There ought to be
nothing that prevents normal messages going about their business -
it's just a regular NSView hierachy. I am using Core Animation layers
in the hierarchy, and have a few sibling views therein deliberately
overlapping others (causing a warning in IB). Could it be that some
issue propagating subview resizing in the Main Window would somehow
prevent continuous resize messages from reaching the drawer's outer
window? That seems like a non-sequitur as the main window ought to be
able to separately indicate its outer frame size changes to the
drawer, irrespective of what is going on within its bounds.
Anyway, I'm stumped (for the moment) and thought I'd fish on the list
for ideas!
