Hi
I am trying create a view in my RCP program that can display an opengl
view. I have the tried the code snippet 209 and everything works well.
however I cannot seem to get this to work under my RCP program. within
the view class I have added the following code under the
createPartControl method.
public void createPartControl(Composite parent) {
parent.setLayout(new FillLayout());
GLData data = new GLData ();
data.doubleBuffer = true;
final GLCanvas canvas = new GLCanvas(parent.getShell(), SWT.NONE, data);
canvas.setCurrent();
final GLContext
context=GLDrawableFactory.getFactory().createExternalGLConte xt();
initialize3DWindow(context,canvas); // initialize the 3D window
create3DWindow(context,canvas); // draw the 3D object
}
The code compiles fine but i don't see anything. Is there any code
examples on how to do this with RCP or any documentation. Any help would
be greatly appreciated.
thanks
Fintan Mac Cormack

Hi,
you seem to be messing around with the Shell of Eclipse. The shell is a
the desktop-window of your eclipse rcp/ide. It's not a good idea to mess
around with it.
Have you tried to remove all these calls to the shell and just do the
following:
public void createPartControl(Composite parent) {
GLData data = new GLData ();
data.doubleBuffer = true;
final GLCanvas canvas = new GLCanvas(parent, SWT.BORDER, data);
canvas.setCurrent();
final GLContext
context=GLDrawableFactory.getFactory().createExternalGLConte xt();
initialize3DWindow(context,canvas); // initialize the 3D
create3DWindow(context,canvas); // draw the 3D object
}
Note that I pass "parent" to the GLCanvas constructor, not
parent.getShell().
parent.getShell() is something you want to leave alone.
Regards,
Stepan
