Detailed Description

Widget of visualisation.

This widget provide a simple system to display visualisation If you only want to visualise a graph, you can call the setGraph function But in other cases you can directly use the GlScene of the GlMainWidget

See also:

GlScene

After scene construction you can perform some operation on GlMainWidgte :

• Selection with doSelect() and selectGlEntities()
• Image output with getImage(), createPicture(), outputSVG() and outputEPS()
• Texture output with createTexture()
• others operation on GlScene and QGlWidget
