wx: Do not delay deletes of wxGraphicContext
|
|
Fixes crash on Mojave, where refresh events are sent early and
invoked recursively the delete of wxGraphicContext was delayed
until after callback returned causing the crash to happen.
|
|
|
|
They can't be constants because the order differ between 3.0.3 and 3.1.
So they must be looked up in runtime.
|
|
|
|
|
|
The user app may want to handle several mouse motion events before
drawing new data for example.
|
|
Added wxDropFiles event
|
|
There seems to be a timeing dependent double delete when doing
reference cleanup after wx:destroy(). wxGraphicsObjects can thus not
be free'ed by wx in the cleanup phase. A guess is that the underlying
rendering context deletes all graphics objects without careeing about
wxWidgets reference counting.
|
|
Commands could be executed twice, if the command was dispatched
from a callback and caused a recursive invocation of command loop.
Solution is to mark op as -1 before calling wxWidgets.
Also commands could be missed when idle processing was done inside
while executing a recursive callback, solved be always resetting peak
index after idle processing is done.
|
|
|
|
|
|
Some events are callbacks inside wxWidgets so idle processing doesn't
take place until operation is completed, for instance move/resize window
on Windows. This way we get some response while mouse button is pressed.
|
|
|
|
It was broken.
|
|
|
|
I had changed the (generatade) code without updating the code generator in commit 38cb91a9.
Fixed now, and also fixed a typo in the generated licence code.
|
|
|
|
Preallocated an rt array of 64 items (which covers 99%) of the calls
and thus avoids allocation and copying in most cases.
|
|
To many floats in return value could cause a reallocation and
pointers to reallocated data. Fix it by ensuring that the temp
float array is large enough before add values to it.
|
|
delete_object used a deleted reference
|
|
On mac and wxWidgets-3.0 the crtlDown field in keyboard and
mouse events are set when command button is pressed.
The ctrl key on mac keyboard is in a field called raw_control as this
would be backward incompatible to add we reuse the metaDown field as
indicator when the ctrl keyboard button is pressed.
|
|
Do not postpone deletion of wx*DC objects since they need to be
deleted directly. Otherwise, if inside showModal, causes an eternal
loop of wxPaint events on Windows.
|
|
Useful class though not documented in wxWidgets-2.8
|
|
|
|
|
|
Remove the extra wxEvtListener that only caused confusion,
now everything is automatically cleaned up by the destructors
and event sent to erlang when it becomes delete for all cases.
|
|
Avoids crashes.
|
|
wxStyledTextCtrl had no wrapper class so, because it was not detected
that it had virtual destructors, thus references to it was not cleaned
up on destruction. When a process dies and wx cleans up the event handlers
access was made to the deleted object and caused a seg fault.
Added a testcase which I thought could provoke the bug but didn't.
|
|
Event handlers was not removed after objects/process had been
delete/died, which causes memory leakage and that fun's was
kept in the wx_server process. Code that might be purged and
the server died.

|
wx-2.9 have changed some functions from returning references to objects to
returning objects instead
|
|
In 2.9 several functions takes enum's instead of int as arguments,
remove dirty -fpermissive fix and fix it correctly instead.
|
|
Prepare to remove functionality which is not available in coming
wxWidgets versions.
|
|
|
|
|
|
Wrong arguments / return values in:
hitTest getItemPosition and getItemRect
|
|
|
|
Some out arguments was in args.
|
|
* Lines had wrong arguments
* Change float() to number in guards, when packing arguments
integers are converted floats to automaticly anyway.
|
|
Needed on mac
|
|
|
|
No rendering context is available until setCurrent is called the
first time, opengl extensions can not be loaded before the rendering
context is created.
|
|
The idea is to build a separate opengl library which can be reused
by other erlang applications.
|
|
The new code generator doesn't resolve macros and a
is missing (not used in wxWidgets) on windows.
|
|
|
|
Changed representation of wxTreeItem to be int.
This saves memory, where the driver don't need to keep a reference map
for every tree item.
And added getFirstChild and getNextChild to wxTreeCtrl.
