- NAME
- getscreenmode_gc -- create getscreenmode BOOPSI objects
-
- SUPERCLASS
- gadgetclass
-
- REQUIRES
- button.gadget
-
- DESCRIPTION
- 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.
-
-
- METHODS

- NAME
- GETSCREENMODE_GetClass -- Gets the pointer to the screenmode
- requester class
-
- SYNOPSIS
- getscreenmode_class = GETSCREENMODE_GetClass();
- D0
-
- Class * GETSCREENMODE_GetClass( void );
-
- FUNCTION
- Obtains the pointer to the getscreenmode gadget class for use with
- NewObject(). This function always returns a valid pointer so
- you do not need to check it. The reason is that if the library
- opens fine, then the pointer returned is already setup. (Of course
- this implies that if opening the library fails, you shouldn't be
- calling this.)
-
- Note that this function does not create the class, that is done
- when the class library is opened.
-
- INPUTS
-
- RESULT
- getscreenmode_class - Pointer to the getscreenmode gadget class.
