cvocvo Posted June 15, 2010 Posted June 15, 2010 So I'm working with a slider, but the kicker here is that I want to constantly probe the Slider value (I know use GUICtrlRead) and push that value into a label next to the slider. I eventually want to have multiple sliders (2) that depend on a main slider's current value. Anyway, what I've got so far is just a modified version of the sample code, but I can't seem to get it to update the slider value in the label. Maybe I misunderstood what is happening in the sample code, but this should be relatively simple. Here's the code I'm working with to get a working version that I can actually implement: #include <GUIConstantsEx.au3> Opt('MustDeclareVars', 1) Example() Func Example() Local $slider1, $button, $msg, $label, $state GUICreate("slider", 220, 300, 100, 200) GUISetBkColor(0x00E0FFFF) ; will change background color $slider1 = GUICtrlCreateSlider(10, 10, 200, 20) GUICtrlSetLimit(-1, 200, 0) ; change min/max value $button = GUICtrlCreateButton("Value?", 75, 70, 70, 20) $label = GUICtrlCreateLabel("Value=" & $state, 75, 100, 100, 20) GUISetState() GUICtrlSetData($slider1, 45) ; set cursor Do $state = GUICtrlRead($slider1) $msg = GUIGetMsg() If $msg = $button Then MsgBox(0, "slider1", GUICtrlRead($slider1), 2) EndIf Until $msg = $GUI_EVENT_CLOSE EndFunc ;==>Example If anyone has any suggestions as to how to do this or even a better way to do this, I'm open to suggestions and help. Thanks
Valuater Posted June 15, 2010 Posted June 15, 2010 Maybe.. #include <GUIConstantsEx.au3> Opt('MustDeclareVars', 1) Global $Slider_hold Example() Func Example() Local $slider1, $button, $msg, $label, $state GUICreate("slider", 220, 300, 100, 200) GUISetBkColor(0x00E0FFFF) ; will change background color $slider1 = GUICtrlCreateSlider(10, 10, 200, 20) GUICtrlSetLimit(-1, 200, 0) ; change min/max value $button = GUICtrlCreateButton("Value?", 75, 70, 70, 20) $label = GUICtrlCreateLabel("Value=" & $state, 75, 100, 100, 20) GUISetState() GUICtrlSetData($slider1, 45) ; set cursor Do $state = GUICtrlRead($slider1) If $state <> $Slider_hold Then GUICtrlSetData($label, $state) $Slider_hold = $state EndIf $msg = GUIGetMsg() If $msg = $button Then MsgBox(0, "slider1", GUICtrlRead($slider1), 2) EndIf Until $msg = $GUI_EVENT_CLOSE EndFunc ;==>Example 8)
Moderators Melba23 Posted June 15, 2010 Moderators Posted June 15, 2010 cvocvo,Two ways to get a reading of the slider value -Firstly, polling in the While...WEnd loop:#include <GUIConstantsEx.au3> $hGUI = GUICreate("Test", 500, 500) $hSlider = GUICtrlCreateSlider(10, 50, 480, 40) $hLabel = GUICtrlCreateLabel("0", 10, 10, 100, 40) GUICtrlSetFont(-1, 24) GUISetState() $iLastSlider = 0 While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE Exit EndSwitch $iCurrSlider = GUICtrlRead($hSlider) If $iCurrSlider <> $iLastSlider Then GUICtrlSetData($hLabel, $iCurrSlider) $iLastSlider = $iCurrSlider EndIf WEndIf you are wondering why we have the $iCurrSlider/$iLastSlider code then try this:#include <GUIConstantsEx.au3> $hGUI = GUICreate("Test", 500, 500) $hSlider = GUICtrlCreateSlider(10, 50, 480, 40) $hLabel = GUICtrlCreateLabel("0", 10, 10, 100, 40) GUICtrlSetFont(-1, 24) GUISetState() While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE Exit EndSwitch GUICtrlSetData($hLabel, GUICtrlRead($hSlider)) WEndSee how the label flickers? That is why you need to limit the GUICtrlSetData calls to when they are needed, not every time round the loop.Secondly a much sexier version:#include <GUIConstantsEx.au3> #include <WindowsConstants.au3> $hGUI = GUICreate("Test", 500, 500) $hSlider = GUICtrlCreateSlider(10, 50, 480, 40) $hSlider_Handle = GUICtrlGetHandle(-1) $hLabel = GUICtrlCreateLabel("0", 10, 10, 100, 40) GUICtrlSetFont(-1, 24) GUISetState() GUIRegisterMsg($WM_HSCROLL, "WM_H_Slider") While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE Exit Case $GUI_EVENT_PRIMARYUP ToolTip("") EndSwitch WEnd Func WM_H_Slider($hWnd, $iMsg, $wParam, $lParam) #forceref $hWnd, $iMsg, $wParam If $lParam = $hSlider_Handle Then GUICtrlSetData($hLabel, GUICtrlRead($hSlider)) EndIf Return $GUI_RUNDEFMSG EndFuncIf you have never used GUIRegisterMsg there is a tutorial in the Wiki whcih explains what it is all about.

(i double checked label and slider numbers). What i doing wrong? Greetings.
BrewManNH Posted June 12, 2017 Posted June 12, 2017 You can't register the same windows message multiple times, it will only register the last one you set. Put all three of your slider checks inside the same function and use something like this. Func WM_H_Slider($hWnd, $iMsg, $wParam, $lParam) #forceref $hWnd, $iMsg, $wParam Switch $lParam Case $hSlider_Handle1 GUICtrlSetData($Label3, GUICtrlRead($Slider1)) Case $hSlider_Handle2 GUICtrlSetData($Label4, GUICtrlRead($Slider2)) Case $hSlifer_Handle3 GUICtrlSetData($Label5, GUICtrlRead($Slider3)) EndSwitch Return $GUI_RUNDEFMSG EndFunc ;==>WM_H_Slider1 This way you can register once, and check all three sliders in the same function.
