This method should initialize the whole implementation graphic with the given GralWindow
and all
GralPanelContent and all
GralWidget into.
It means it is the new concept since ~2016/18 established for all in 2022:
- First create the graphic independent graphic description data.
- 2th create the proper Factory
- 3th with this operation create the implementation graphic as a whole.
Using specific GralFactory implementors can enable also other graphic systems.
Examples see ViewCfg.
It creates the implementation graphic manager, primary window and the graphic thread.
Set a breakpoint in GralMng.runGraphicThread to follow step by step what is done for creation.
