Hello,

I have an old application consisting of a SWT composite that contains four GLCanvas.
This old application used to work with JOGL 1.

I've ported it to JOGL 2 and almost everything is working fine.

The problem comes when I change GLCanvas layout order. By calling moveBelow(Composite) method on these GLCanvas, the rendering is stopped !

I have no idea to solve the issue ;-(

Any help would be very appreciated ?

Thanks,
frank

PS : I'm far from being an OPENGL developer, which means that I am certainly misusing the OPENGL API

Here is the code used to change layout :

                if (legendPosition != this.legendPosition) {
                        if (legendPosition == SWT.TOP)
                                legendArea.moveBelow(leftAxisArea);
                        else
                                legendArea.moveBelow(bottomAxisArea);
                        legendArea.setVisible(true);
                        showLegend = true;
                        layout(true);
                        this.legendPosition = legendPosition;
                }
