button.gadget
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.
OM_NEW -- Passed to superclass, defaults set, then OM_SET. Children
created.
OM_SET -- Passed to superclass, custom tags set.
OM_GET -- Custom tag returned or passed to superclass.
OM_UPDATE -- Passed to superclass, options set then rendered.
OM_DISPOSE -- Children disposed of, then passed to superclass.
GM_RENDER -- Passed to superclass, then children are rendered.
GM_HITTEST -- Overrides superclass, returns GMR_GADGETHIT if within
the popscreenmode button.
GM_HELPTEST -- Overrides superclass, returns GMR_HELPHIT if within
the domain of the gadget.
GM_GOACTIVE -- Passed to superclass, passed to popfile/drawer button.
GM_HANDLEINPUT -- Overrides superclass, all input processed.
GM_GOINACTIVE -- Passed to superclass, popfile/drawer button deactivated.
GM_DOMAIN -- Returns GDOMAIN_MINIMUM and GDOMAIN_MAXIMUM dimensions.
GM_KEYACTIVE -- Private method for keyboard control.
GM_KEYINACTIVE -- Private method for keyboard control.
GSM_REQUEST -- getscreenmode gadget method for invoking the screenmode requester.
Most of these tags operate the same as the ASLSM_#? tags in ASL library.
See <asl.library/AslRequest> for detailed descriptions.
