Hi Yu,
here’s a snippet of an app using osg inside a classic Cocoa-app. The trick is
to let osg create a view only and then add this view into your
NSView-hierarchy.
osg::ref_ptr<osgViewer::GraphicsWindowCocoa::WindowData> win_data = new
osgViewer::GraphicsWindowCocoa::WindowData(
osgViewer::GraphicsWindowCocoa::WindowData::CreateOnlyView |
osgViewer::GraphicsWindowCocoa::WindowData::CheckForEvents
);
// self is a NSWindow/NSView
osg::ref_ptr<osg::GraphicsContext::Traits> traits = new
osg::GraphicsContext::Traits();
traits->inheritedWindowData = win_data;
traits->x = 0;
traits->y = 0;
traits->width = [self frame].size.width;
traits->height = [self frame].size.height;
traits->doubleBuffer = true;
traits->vsync = true;
traits->windowDecoration = false;
traits->supportsResize = false;
// the following steps are deep inside my own app and it’s to cumbersome to
quote them here.
// 1. create the graphics-context with the traits-object
// 2. create a osg::Viewer or a osg::View and set the gc accordingly.
// 3. realize the graphics-context
// 4. after realizing the GraphicsContext you can get the created view via the
win_data-object.
openglView = win_data->getCreatedNSView();
[self addSubview: openglView];
[openglView setFrame: NSMakeRect(0, 0, [self frame].size.width, [self
frame].size.height)];
Another approach is the usage of GraphicsWindowEmbedded, here you’ll create and
control the OpenGL graphics-context by yourself.
HTH,
Stephan
