bugs in the Carbon-implementation of GraphicsWindow, so here's another
fix for setWindowDecorationImplementation, now updates the
titlebar-height, and fixes some display-issues when switching the
decoration on/off.
"
Stephan: "attached you'll find some modifications to the GraphicsWindow-class and
their platform-dependant implementations.
The problem:
setWindowRectangle and setWindowDecoration do not update the
traits-object, so, if you call setWindowRectangle on a
not-realized-window it will open with another size when realized later.
getWindowRectangle reports possible wrong sizes if setWindowRectangle
called before.
My solution:
split the implementation in two parts:
GraphicsWindow::setWindowRectangle will update its traits-object and
call afterwards the virtual method setWindowRectangleImplementation
(which is implemented by the derived platformspecific classess). For
setWindowDecoration I am useing a similar mechanism.
I hope you'll find the submission useful, the Win32 and X11 changes are
not tested but should work."
Changes to this made by Robert are call of resized in setWindowRectangle
instead of setting of Traits, and use of a bool return type.
changes I made:
+ put a warning in the console if a nonexistant screen is requested
+ add getters for the aglcontext and pixelformat -- I need access to
them in my own code.

window.
The win32 implementation is still in its original shape since I have no win32
implementation available.
I have chosen the enum approach for the first cut. That is benefitial since
the user does not need to track creation of mouse cursors for different
windows and displays in presence of multiple viewer windows.
The default set of available mouse shapes is the same set that was available
with glut. That set served many OpenGL applications well, so the hope is that
this is enough.
Even though, that implementation is still extensible:
I have digged out the way SDL defines new mouse cursors and added a still
documented out function prototype in the GraphicsWindow that can be used to
extend the current implemtation for arbitrary mouse shapes. That is not
implemented yet.
I hope that somebody with a win32 test system can catch up that implementation
on win32."
implementation of GraphicsWindow:
- usage of WindowData, you can specify an existing window to use via
osg::Traits
- implementation of setScreenResolution and setScreenRefreshRate
- implementation of setWindowDecoration when window is already created.
There seems to be a bug regarding multiple threads and closing windows,
see my other mail on osg-users.
"
selectively set the pixel format for windows that are inherited, following
some discussions on the mailing list last week.
This is implemented through a new traits flag
(setInheritedWindowPixelFormat) with a default state of false (to avoid
breaking existing applications). When set to true, the pixel format of the
inherited window will be set according to the traits specifications.
"
Most of the code is from the osgviewer application, I have took the fullscreen handler and the threading one, and I have just added a fonctionality to be able to change the screen resolution in windowed mode."
a collegue of mine noticed that on Windows and X11 the modifier state (such as
Alt or Ctrl) would be applied one key press too late: e.g. press & hold Alt,
press a, release Alt, press a, press a would generate the key sequence a,
Alt-a, a instead of Alt-a, a, a.
The problem is also present on Carbon. Moving the call to setModKeyMask in
front of the call to keyPress fixed it for me on Carbon and X11. I suppose
that this will fix the problem for Windows as well."
returned from Viewer::getContexts/getWindows will be the left most window on the lowest screen number.
Added ability for StatsHandler and HelpHandler to support end users setting their
Camera's graphics context.
