GL contexts and GC blits don't work, dialog placement doesn't work,
and checkbox animations seem to interefere with updating --- but at
least things mostly work.
Relevant to racket/racket#1547
Adjust a workaround for versions before 3.22 when setting the font for
a control.
GTK+ version 3.22 starts paying attention to whether a font size for a
control is absolute (as opposed to being in points), so the workaround
that was put in place for earlier versions breaks.
In addition, some part of the drawing stack seems to round point sizes
to an integeral size after DPI conversion. Take that rounding into
account when setting the font size in `normal-control-font`.
Closes#1522
There's no run-time representation of `NSApplicationDelegate`, so
trying to declare it ands up adding NULL as a protocol to the
Objective-C class for the application delegate.
Adding NULL that way leads to a crash on 10.12.1+ with TouchBar
support.
Closesracket/racket#1520
It would occasionally drop the last digit in the message field.
This turned out to be a bug where the number, while smaller, was wider.
For example:
11111
10101
In variable width fonts the second one will be wider
On 10.11 in 64-bit mode, showing a frame with a PSMTabBarControl
instance somehow causes the event loop to become occupied on
mouse movements, so that moving the mouse in a `2htdp/universe`
program is slow when more than one tab is open in DrRacket. The
modern MMTabBarView widget doesn't have that problem. Also, the
MMTabBarView widget has a Yosemite look (to replace Aqua).
Make the `focus` method shift focus to a floating frame. Also, shift
focus away from the floating frame when `focus` is used in an window
within the current main frame.
Try to tell Macs with two graphics cards that it's ok to
use the low-performance one for the GC bitmap (when
GL is used for that, which is OS X 10.11 and later).
Provided by Eli Barzilay.
This approach is better than a separate process, because creating
too many processes can overwhelm the OS. Also, MCI supports more
sound formats.
Add more agressive re-enabling of screen updates and explicit `update`
calls to avoid partially refreshed frames and never-updated titlebars
on El Capitan.
Also, use `close` instead of `orderOut` to hide a frame. That fixes
problems with closing windows that are in fullscreen mode.
Closesracket/drracket#33
The GC blit implementation used on Mc OS X 10.11 assumed that
the no-GC bitmap is blank. Make it use the given no-GC bitmap.
Also, repair the left-to-right flipping(!) of the GC bitmap,
and repair a backing-scale mismatch that could leave a thin
border around a GC blit.
A relatively late correction to refresh handling for El Capitan
(commit 9bf18505d5) causes a canvas to be refreshed too often
in some cases. Delay the refresh to restore the old timing
without the old bug.
Opening a shared object in global mode risks conflicts with
other shared objects, but opening only one library that way
will hopefully not create conflicts.
