GETSCREENMODE_GetClass

gadgetclass

The getscreenmode gadget class is used to get screenmodes from a screenmode requester in an easy and consistent way. It consists of two button gadgets, one read-only and one popscreenmode button, that are used to select the screenmode and show the result.

Advantages that this class provides:

• Consistent behaviour and look in all applications using this class instead of doing their own screenmode selection routines.
  
  
• Easy to use.
  
  

Most of these tags operate the same as the ASLSM_#? tags in ASL library. See <asl.library/AslRequest> for detailed descriptions.
