Simple test program to test aspect ratio resizing (560 bytes, text/plain)

Description Billy Biggs 2004-08-11 01:01:56 UTC 
Windows which set the aspect ratio hints can only be resized by their corners. 
If you grab the sides and try to resize the window, the window size bounces
about one or two pixels, but won't let you resize it further.  Furthermore,
while the sides are effectively unavailable to use as resize handles, the cursor
still changes to show resizing.

The behaviour I would like to see would be that resizing a fixed-aspect window
by its sides results in the window growing by an appropriate amount in the other
axis.  If you want to only allow resizing of fixed aspect ratio windows by the
corners, metacity should change the window border to give a visual indication:
maybe by changing the cursor, or removing the border completely except in the
corners.  As it is now, I believe the user experience is too challenging if the
user do not already expect the window to have a fixed aspect ratio.
Comment 1 Rob Adams 2004-08-11 01:09:25 UTC 
I'd happily accept a patch to do this, but its a pain to implement and there are
much higher priority things.
Comment 2 Havoc Pennington 2004-08-11 23:12:29 UTC 
I think it's fairly high priority to rewrite constraints.c (again), but it sure
is a ton of work.

It might be useful to collect some of the relevant past discussions, e.g. Alan's
suggestion to use regions to rewrite it, just in case someone appears who has
time to fix this up.

Simple test program to test aspect ratio resizing

I'm attaching this because I've been working on this bug (among many others) in
the constraints_experiments branch and wanted to have this here for reference,
but also to make it easier for gtk+ hackers to find a testcase since I may need
to ping them about part of this.  (My implementation mostly works, ignoring
suboptimal interactions with fully-onscreen constraints since that has not yet
been tackled, but I believe gtk+ is being anal about how closely the constraint
is satisfied and by so doing is causing drift.	For example, user resizing from
the right side of the window can make the window drift vertically in addition
to resizing vertically due to these unwanted configure requests being
received.)
