GUI Item Order

[Steve0]

Hey guys,

I've got a number of standard pictures on a GUI overlapping each other. Using the GUICtrlOnHover UDF I've been trying (unsuccessfully) to have the images "bring to front". Koda has this option when editing the GUI, but doing so makes no changes in the form code.

Setting the Ctrl State to $GUI_FOCUS, $GUI_ENABLE, $GUI_SHOW or $GUI_ONTOP makes no difference, nor does setting the Ctrl Style to $WS_EX_TOPMOST.

Any other suggestions?

Many thanks

Steve0,

This is a bit sledgehammer/nut but it does work:

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <Array.au3>

Global $aLabels[4], $aColours[4] = [0xFF0000, 0xFFFF00, 0x00FF00, 0x0000FF]

$hGUI = GUICreate("Test", 500, 500)

$hStart = GUICtrlCreateDummy()
$aLabels[0] = GUICtrlCreateLabel("", 10, 10, 100, 100)
GUICtrlSetBkColor(-1, $aColours[0])
$aLabels[1] = GUICtrlCreateLabel("", 60, 60, 100, 100)
GUICtrlSetBkColor(-1, $aColours[1])
$aLabels[2] = GUICtrlCreateLabel("", 110, 110, 100, 100)
GUICtrlSetBkColor(-1, $aColours[2])
$aLabels[3] = GUICtrlCreateLabel("", 160, 160, 100, 100)
GUICtrlSetBkColor(-1, $aColours[3])

GUISetState()

$hLastCtrl = 0

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch

    $aInfo = GUIGetCursorInfo($hGUI)
    If $aInfo[4] <> $hLastCtrl And $aInfo[4] <> 0 Then
        ConsoleWrite("Current Ctrl: " & $aInfo[4] & @CRLF)
        $iIndex = _ArraySearch($aLabels, $aInfo[4])
        ConsoleWrite("Index: " & $iIndex & @CRLF)
        $aPos = ControlGetPos($hGUI, "", $aInfo[4])
        GUICtrlDelete($aInfo[4])
        $aLabels[$iIndex] = GUICtrlCreateLabel("", $aPos[0], $aPos[1], $aPos[2], $aPos[3])
        GUICtrlSetBkColor($aLabels[$iIndex], $aColours[$iIndex])
        $hLastCtrl = $aLabels[$iIndex]

    EndIf

WEnd

I will try and come up with something better!

Hi there.

Just a tweak to Melba's

Redraw the control instead of deleting and remaking.

#include <GUIConstantsEx.au3>
#include <Array.au3>
#include <Winapi.au3>
Global $aLabels[4], $aColours[4] = [0xFF0000, 0xFFFF00, 0x00FF00, 0x0000FF]

$hGUI = GUICreate("Test", 500, 500)
$over=10
for $i=0 to 3
    $aLabels[$i] = GUICtrlCreateLabel("", $over, $over, 100, 100)
    GUICtrlSetBkColor(-1, $aColours[$i])
    $over=$over+50
Next

GUISetState()
$hLastCtrl = 0
While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
    $aInfo = GUIGetCursorInfo($hGUI)
    If $aInfo[4] <> $hLastCtrl And $aInfo[4] <> 0 Then
        $hLastCtrl=$aInfo[4]
      _WinAPI_RedrawWindow(GUICtrlGetHandle($aInfo[4]))
    EndIf

WEnd

picea892,

I knew there must be a better tool than a sledgehammer out there! Thanks for pointing it out!

Many thanks for the quick response guys, works well!

[Steve0]

Sorry guys, the example worked perfectly... maybe I'm not translating it correctly here... I've tried using the picea892 method, and it looks... funny. I've made up a sample of what I'm trying to get at using some standard WinXP graphics (not sure if they're still there on other editions):

#include <GUIConstantsEx.au3>
#include <WinAPI.au3>
#include <WindowsConstants.au3>

$TestWindow = GUICreate("Overlay Test", 300, 300, 150, 200, 0x00000000, 0x00000000)
$Background = GUICtrlCreatePic("C:\WINDOWS\Web\Wallpaper\Ascent.jpg", 0, 0, 300, 300)
GUICtrlSetState($Background, $GUI_DISABLE)
GUICtrlCreatePic("C:\WINDOWS\Web\Wallpaper\Autumn.jpg", 10,10,100,100)
GUICtrlCreatePic("C:\WINDOWS\Web\Wallpaper\Azul.jpg", 60,60,100,100)
GUICtrlCreatePic("C:\WINDOWS\Web\Wallpaper\Autumn.jpg", 110,110,100,100)
GUISetState(@SW_SHOW, $TestWindow)

$hLastCtrl = 0
While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
    $aInfo = GUIGetCursorInfo($TestWindow)
    If $aInfo[4] <> $hLastCtrl And $aInfo[4] <> 0 Then
        $hLastCtrl=$aInfo[4]
        _WinAPI_RedrawWindow(GUICtrlGetHandle($aInfo[4]))
    EndIf

WEnd

Making use of the WinAPI command to refresh the window but with my old code, it still doesn't "bring to front". Here's the method I was using before, utilising MrCreatoR's GUICtrlOnHover script:

#include <GUIConstantsEx.au3>
#include <WinAPI.au3>
#include <GUICtrlOnHover.au3>
#include <WindowsConstants.au3>

$TestWindow = GUICreate("Overlay Test", 300, 300, 150, 200, 0x00000000, 0x00000000)
$Background = GUICtrlCreatePic("C:\WINDOWS\Web\Wallpaper\Ascent.jpg", 0, 0, 300, 300)
GUICtrlSetState($Background, $GUI_DISABLE)
GUICtrlCreatePic("C:\WINDOWS\Web\Wallpaper\Autumn.jpg", 10,10,100,100)
_GUICtrl_OnHoverRegister(-1, "_Hover_Func", "_Leave_Hover_Func")
GUICtrlCreatePic("C:\WINDOWS\Web\Wallpaper\Autumn.jpg", 60,60,100,100)
_GUICtrl_OnHoverRegister(-1, "_Hover_Func", "_Leave_Hover_Func")
GUICtrlCreatePic("C:\WINDOWS\Web\Wallpaper\Autumn.jpg", 110,110,100,100)
_GUICtrl_OnHoverRegister(-1, "_Hover_Func", "_Leave_Hover_Func")
GUISetState(@SW_SHOW, $TestWindow)

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch

WEnd



Func _Hover_Func($iCtrlID)
    GUICtrlSetImage($iCtrlID, "C:\WINDOWS\Web\Wallpaper\Azul.jpg")
    _WinAPI_RedrawWindow($iCtrlID)
EndFunc

Func _Leave_Hover_Func($iCtrlID)
    GUICtrlSetImage($iCtrlID, "C:\WINDOWS\Web\Wallpaper\Autumn.jpg")
    _WinAPI_RedrawWindow($iCtrlID)
EndFunc

Any more assistance would be greatly appreciated!

Hi there.

First Example

You'll have to exclude any controls you don't want to be affected. Your background picture becomes first and makes the "funny" effect. So you need to make this change

If $aInfo[4] <> $hLastCtrl And $aInfo[4] <> 0 And $aInfo[4] <> $Background Then

Second Example (Mr. Creator)

You need to you use the redraw script with a handle not an ID. So your code would look like this.

_WinAPI_RedrawWindow(GUICtrlGetHandle($iCtrlID))

[Steve0]

Superb! Both work perfectly.

Many thanks for your help!
