ColorPicker UDF

[Marcelos]

Hi

thanks for the fast response,

i tryed some codes , trying to implement the sugested solution .

at the ent i came up with this solution.

1- i commented the registration from the "colorPicker.au3"

;~ GUIRegisterMsg($CP_WM_ACTIVATE, 'CP_WM_ACTIVATE')
;~ GUIRegisterMsg($CP_WM_COMMAND, 'CP_WM_COMMAND')
;~ GUIRegisterMsg($CP_WM_MOUSEWHEEL, 'CP_WM_MOUSEWHEEL')
;~ GUIRegisterMsg($CP_WM_SETCURSOR, 'CP_WM_SETCURSOR')

2- i added to "Func CP_WM_COMMAND"  the case options to handle the controls in my form  (see "my code" )

Func CP_WM_COMMAND($hWnd, $iMsg, $wParam, $lParam)

    ; Handler from ColorChooser.au3
    If (IsDeclared('__CC_WM0111')) And (Not Eval('__CC_WM0111')) Then
        $__CP_WM0111 = 1
        Call('CC' & '_WM_COMMAND', $hWnd, $iMsg, $wParam, $lParam)
        $__CP_WM0111 = 0
    EndIf

    For $i = 1 To $cpId[0][0]
        If $cpId[$i][1] = $lParam Then
            If Number($wParam) > 0 Then
                If Not CP_PickerDlg($i) Then
                    Return 0
                EndIf
            EndIf
            ExitLoop
        EndIf
    Next

    Switch $wParam
;----------------My Code -------------------------------
    Case $buttonApply
    .......   
    Case $PickerMessageBackground
    ......   
    Case $PickerTopBackground
    .... 

;-------------- end my code ------------------

EndSwitch
    Return $GUI_RUNDEFMSG
EndFunc   ;==>CP_WM_COMMAND

3- in my form  i registered the 4 functions commented in  "colorPicker.au3"

; ---------   here is my form and controls
....
;--------------------

GUISetState(@SW_SHOW)

UIRegisterMsg($CP_WM_ACTIVATE, 'CP_WM_ACTIVATE')
GUIRegisterMsg($CP_WM_COMMAND, 'CP_WM_COMMAND')
GUIRegisterMsg($CP_WM_MOUSEWHEEL, 'CP_WM_MOUSEWHEEL')
GUIRegisterMsg($CP_WM_SETCURSOR, 'CP_WM_SETCURSOR')

    While 1
              If $fFlag = True  Then
            $fFlag = False
            GUISetState(@SW_HIDE,$Gui)
            GUIDelete($Gui)
            ExitLoop
        EndIf

        sleep(5)
    Wend
    GUIRegisterMsg($WM_COMMAND, "WM_COMMAND")
EndFunc

4- and before exiting the form . i re- registered "wm_command"

 

Thanks for the help

Awesome work, thanks Yashied, you saved me a lot of time.

I'd like to disable that "fade in" effect when you choose a color though, it looks weird in my GUI since the color of the object is switching instantly, but then the ColorPicker is fading to the new color slowly so yeah... it doesn't look right, better if it was instant switch, I'm still searching what to modify to get that.

I'm having some weirdness happen when I try to combine this ColorPicker with >andybiochem's GraphGDIPlus UDF.  I originally took Example #3 from the base post as a start then cut it down to Example #1, and both work fine until I add in a graph from the above mentioned UDF in the same program.

I took my fairly large program and snipped it down to a smaller version that exhibits the same issue.  Here's some sample code (requires GraphGDIPlus.au3 and ColorPicker.au3):

expandcollapse popup

#include "GraphGDIPlus.au3" ; Used for graphing window
#Include "ColorPicker.au3" ; Graph options

_Main()

Func _GraphOptionsGui($GUI) ; Draw and handle the Graph options GUI
   Local $tempPos = WinGetPos("Test")
   $GraphGUI = GUICreate("Graph Settings", 250, 100, $tempPos[0]+50, $tempPos[1]+50, -1, -1, $GUI)

   GUICtrlCreateLabel("Color", 10, 10)
   $Picker = _GUIColorPicker_Create('Picker', 10, 25, 60, 23, 0xFF6600, BitOR($CP_FLAG_DEFAULT, $CP_FLAG_TIP))
   GUISetState()
   
   While 1
      $msg = GUIGetMsg()
      Select
         Case $msg = $GUI_EVENT_CLOSE ; OR $msg = $exititem
            _GUIColorPicker_Delete($Picker)
            GUIDelete($GraphGUI)
            ExitLoop
      EndSelect
   WEnd
EndFunc

Func _Main()
   $GUI = GUICreate("Test",350,360)
   $settingsmenu = GUICtrlCreateMenu("&Settings")
   $graphoptions = GUICtrlCreateMenuItem("Change &Graph settings", $settingsmenu)

   ; Comment out the following line to see the bug go away
   $Graph = _GraphGDIPlus_Create($GUI,10,10,330,320,0xFF000000,0xFF88B3DD)

   GUISetState()

   While 1
      $msg = GUIGetMsg()
      Select
         Case $msg = $graphoptions
            _GraphOptionsGui($GUI)
         Case $msg = $GUI_EVENT_CLOSE
            ExitLoop
      EndSelect
   WEnd
EndFunc

Basically, the problem is that when you go to the Graph Settings menu and double click on the "Picker" button.  When you double click it seems to create an extra copy of the color picker menu with the 5 x 8 grid of colors, and the second copy becomes non-interactive while on top of everything.  Clicking Picker button once and then picking a color works fine - it's just if a stray second click lands on the button that it messes up.

The weird part is that if you comment out line #31, the bug goes away.  All that line does is draw the graph on the main part of the GUI, which should be unrelated to the color picker.

Any ideas as to why this combination of UDFs would be having this issue?  Many thanks in advance!

Edit: Removed colorchooser and switched to example #1 since I can isolate the problem down to just colorpicker now.

It seems that Func CP_PickerDlg($ID) in ColorPicker.au3 is having trouble triggering the following lines correctly when the graph exists:

Switch $Msg
            Case $GUI_EVENT_CLOSE, $cpId[0][3]
