How to notify Coloradjust Object properly to get proper response?
I have tried all available InputMode values already: RelVerify, Toggle, Immediate.
I set notification on Pressed attribute like this"

Code:
```
domethod(ca,[MUIM_Notify, MUIA_Pressed, MUI_TRUE, MUIV_Notify_Self,2,MUIM_CallHook,get_colHook])
```
The procedure installed as a hook looks like this:

Code:
```
DEF get_colHook:hook

	PROC get_col()
		get(ca,MUIA_Coloradjust_RGB,[col])
		StringF(rgb,'zh[8]',col)
		set(str_hex, MUIA_String_Contents, rgb)
		set(str_dec, MUIA_String_Contents, rgb)
		WriteF(rgb, 'dn')
	ENDPROC
```
And inside the main() procedure:

.Code:
```
 installhook(get_colHook, {get_col})
```
To simplify things I made all variables global. And everything would be ok for me except the Coloradjust gadget response only when one clicks outside the triangle and outside the thick circle. When I click inside the triangle or onto the thick color ring the notification seems to not work.

I miss draggable screens... and do you? I know I'm in a minority unfortunately.

get(ca,MUIA_Coloradjust_RGB,{col})
```

Why don't you create a notify on MUIA_ColorAdjust_RGB?

Code:
```
domethod(ca, [MUIM_Notify, MUIA_ColorAdjust_RGB, MUIV_EveryTime, MUIV_Notify_Self, 2, MUIM_CallHook, get_colHook])
```
Also better use subclassing, then you can use own methods instead of hooks.

Yeah, hooks are more or less obsolete. There were a good idea for hooking into system libraries, but in MUI they were always a bad solution.

There are a few classes which are not supporting methods, but generally you can use notifications.

Same goes for lists. Avoid hooks for construct, destruct, sort and co. Just use the methods provided by mui. It is much less work as you dont need to deal with all the shit hooks and code jumps deliver. Just a clean method you receive when something happens and you are done.

Of course this means subclassing, but it is not as bad as it sounds. once you have a proper source file to subclass something, you can simply use it everywhere and it is a nobrainer.

Also if you create a fancy subclass in application one you can simply use that as often as you want and even copy it over to other applications of yours.

Just take a look onto the system settings. The main settings application is just a pile of icons or a list with the settings panels. The panels itself are separate binaries and even inside those panels gui elements come from additional files like the blankers or the usb hardware driver.

Those panels are also used during system installation as well, so going the mui sub class way is the smart way, even if it at first takes some time to understand.

Thanks. Now it works with the whole gadget

But hooks are better than putting all the handling stuff into MUI's main loop in SELECT CASE ENDSELECT block, and that was the way I did in my very first E/MUI programming attempts

There's still something wrong in my code. Now the hook is executed each time the color changes, but it allways returns the same color value.
And I forgot to mention now I use ECX to make use of your Lamp module.

When using subclassing, the main MUI "loop" looks like this:
Code:


     DoMethod(app, MUIM_Application_Run)

Here is an example of how a MUI program in ecx looks like (with my own mui extensions):
The main source:
Code:


OPT PREPROCESS, STACK = 32678 -> SEHR WICHTIG! Sonst gibts Hits, wenn AboutMUI oder meine AboutBox offen war!!!
OPT EXENAME = 'ofdbMUI'

MODULE '*mods/myApp' -> APP_NAME, APP_AUTHOR, APP_VER

MODULE 'dos/dos', 'dos/rdargs'
MODULE 'muimaster', 'new/muimaster'
MODULE 'utility/tagitem', 'amigalib/boopsi' -> for doSuperMethodA
-> my own public modules
MODULE 'libMUI', 'mccSupport', 'muiSupport'
MODULE 'myDebug', 'ezRequester'
MODULE '*mods/lstMovies_mcc', '*mods/winMain_mcc', '*mods/app_mcc'

-> shell args stuff
#define ARGS_TEMPLATE 'E-Source/M,VERBOSE/S'

OBJECT myArgs
	srcs: PTR TO LONG	-> the source file(s)
	verbose
ENDOBJECT

VERBOSE MACRO IF args.verbose = DOSTRUE THEN 1

DEF 
	rda = NIL: PTR TO rdargs, args: PTR TO myArgs

PROC main() HANDLE
DEF app=NIL

	NEW args
	IFN rda := ReadArgs(ARGS_TEMPLATE, args, NIL) THEN Raise("ARGS")

	OpenMuiMasterLib()
	InitClasses 3
	AddNewClass MyApp
	AddNewClass WinMain
	AddNewClass LstMovies

	IF ClassesSetup()
		app := MyAppObject, End
		IFN app THEN Raise("APP")

		set(winMain, MUIA_Window_Open, MUI_TRUE)
		DoMethod(app, MUIM_Application_Run)
		set(winMain, MUIA_Window_Open, FALSE)
	ELSE
		PrintF('ClassesSetup() failed!!!n')
	ENDIF

EXCEPT DO
	SELECT exception 
		CASE "ARGS"; DOSError(NIL)
		CASE "APP" ; PrintF('ERROR: Failed to create Application!n')
	ENDSELECT
	
	IF rda THEN FreeArgs(rda)
	END args
	
	IF app THEN MUI_DisposeObject(app)
	
	ClassesCleanup()
	CloseMuiMasterLib()
ENDPROC

In this module I put all methods of all my subclasses, so I need to import only this module:
Code:


OPT MODULE, MODNAME='myApp'
OPT PREPROCESS, EXPORT

MODULE 'utility/tagitem', 'intuition/classes', 'workbench/workbench'
MODULE 'libMUI', 'mccSupport', 'muiSupport'

CONST MUISN_IGRACKI		= <put your own mui serial here!>
CONST TAGBASE_IGRACKI	= TAG_USER OR (MUISN_IGRACKI SHL 16)

-> change these 3 defines
#define APP_VER		  '1.0'
#define APP_NAME 	  'ofdbMUI' -> CHANGEME
#define APP_AUTHOR	  'Thomas Igracki' -> CHANGEME

#define APP_VERSION	  '$VER: ' + APP_NAME + '_' + __TARGET__ + ' ' + APP_VER + ' ' + __AMIGADATE__ + ' by ' + APP_AUTHOR + ''
#fmtstr APP_COMPILED  'Compiled: s s for s - ECX vs' __DATE__ __TIME__ __TARGET__ ECX_VERSION
#define APP_COPYRIGHT '(c) 2014'


#define DOSError(str) PrintFault(IoErr(), IF str THEN str ELSE APP_NAME)

-> Now all attributes and methods of ALL my subclasses, so every module can access them

->>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

ENUM
	MA_MyApp_Base = TAGBASE_IGRACKI

	methodID: LONG
	forStr: PTR TO CHAR
ENDOBJECT

And a subclass, winMain_mcc.e:
Code:


OPT PREPROCESS, MODULE, MODNAME='winMain_mcc'

MODULE 'exec/libraries', 'exec/lists',
	   'mui/muicustomclass', 'muimaster','new/muimaster', 
       'intuition/classes','intuition/classusr','intuition/screens','intuition/intuition',

       'workbench/startup', 'workbench/workbench',
       'amigalib/boopsi', -> 
       'dos/dostags'
->MODULE 'libraries/asl'

MODULE 'mui/StringHistory', 'mui/Lamp'

-> my modules
MODULE 'myDebug', 'libMUI', 'mccSupport', 'muiSupport', 'MUInames', 'ezRequester'
MODULE '*myApp', '*lstMovies_mcc'
