Method Detail

createGraphic

public abstract void createGraphic(GralMng gralMng,
                                   char sizeShow)

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.

Parameters:

windowg -

sizeShow - 'A' ... 'G' for the size, pixel per grid

log - a log necessary?

getFactory

public static GralFactory getFactory(java.lang.String implementor)

Returns a proper factory due to the implementor String

Parameters:

implementor - "SWT" or "AWT"

Returns:

null on faulty implementor string
