Shaders problem with OpenSceneGraph and osgQT

[kragnfrol]

Hi !

I hope someone here will be able to help me.

Here is my problem : I'm working on a GIS app based on Qt, OpenScenegraph and OpenGL.

I'm using dockable widgets, based on osgQt::GLWidget, which is a QGLWidget.

I can load images and display them in thoses widgets, and I can also apply shaders (in GLSL).

But if I

• Load an image into a widget
• load an apply a shader to this image
• close the widget
  then this shader won't work for any of the next widgets I could Open.

It's ok for other shaders.
It's ok for next widgets as long as I do not close one of them.

Any kind of help / hint is good, I made all the search I could about it and didn't find anythings.

Cheers,

Valerian
