Re: [platform-swt-dev] Eclipse on OS X 10.2 Developer Preview
|
Hi,
I recently saw Eclipse F1 running (using the term lightly) on OS X
10.2 developer preview, and the UI was completely smashed against
the top of the window rendering it totally unusable. You can not
even see the edit pane. I'm not sure if this is a bug in OS X 10.2
or not, but other apps seem NOT to be affected with similar issues,
and the same executable does not show this behavior in OS X 10.1.5.
I found the (trivial) problem:
Since 1984 the Control Manager has the following problem: hit
detection and drawing of child controls are performed in the same
order (which is wrong). This is not a problem as long as child
controls are not overlapping. However in Eclipse controls are
overlapping, so sometimes you could not select a control that seems
to be visible. As a workaround I've reversed the insertion order of
controls that were added to a composite control.
In Jaguar Apple introduced the HIView. This is a good thing because
after almost 20 years the Mac toolbox (aka Carbon) gets a real 'view
system' with 'normal' hit detection and drawing semantics (and other
good stuff). However for this Apple had to reverse the insertion
order. As a consequence all layouts in Eclipse are backwards on
Jaguar.
My next drop will have a fix for this.
