SOLVED Customgui for ShaderLink

Is there any customGui which adds a ShaderLink to a GeDialog? I noticed that there was some customGui for Links and Texture but I could not find any for ShaderLink.
Thank you.

As you can read in the documentation, the custom GUI for SHADERLINK is TexBoxGui, which has the custom GUI ID CUSTOMGUI_TEXBOX.

See also Custom GUI Elements.

Thank you! That's what I needed.

This is still missing in the Python SDK .....
