Re: [gef3d-dev] Rendering SWT as OpenGL Texture

[Christoph Caks <ccaks@xxxxxxxxxxxxxxx>]

Hi,

since you said you use widgets as overlays all the time i gave it another shot:
 
and i finally figured out how to get my widgets above my GLCanvas:
i just needed to call somewidget.moveAbove(myGlCanvas). If i don't do this the glcanvas is always on top of my widget - regardless of the order i added them.
For now i can use this to display the swt content as overlay

btw jens, the direct editing demo looks great ;-)

thanks and greetings,
Christoph

I just create a widget and move it to where I want it in the (SWT) container -- just requires a couple of translations from the widget location. Is this what you guys mean? Because in this case, there isn't any way for GEF3D or GEF to overlay the widget, right?

For example, ToolTips are SWT based overlays, and they also work with GEF3D although we do not handle them in any way in GEF3D. This is why they are placed at the wrong location. Another example of this overlay technique used in GEF is DirectEdit. In GEF, labels can be directly edited. While this looks as if the label is edited by GEF/Draw2D, it actually is an SWT widget placed on top of the label. In 2D, this trick is not visible, it looks as if the label is edited. Actually, this "trick" also worked in GEF3D, and I'm a little bit surprised that it isn't working anymore. However, you can now directly edit text in GEF3D, although we haven't implemented that yet. I've made a little movie showing overlays and the direct edit stuff:
