$WS_EX_TRANSPARENT not working with GUI no background

Recommended Posts

MasonMill

Hey guys,

Im posting a new thread out of a necro post as per Melba.

I edited a .gif picture to make a transparent background (with photoshop). When I try to add this picutre into my gui, it makes the background of my picture white. I dont want any background on my picture. I just want the image alone alone with nothing around it. Using a previous post I was able to do so using the code below.

#include <GUIConstants.au3>

HotKeySet("{END}", "Terminate")

$gui=GUICreate("test transparentpic", 47, 45)
$pic=GUICreate("", 47, 45, 0, 0,$WS_POPUP,BitOr($WS_EX_LAYERED,$WS_EX_MDICHILD,$WS_EX_TRANSPARENT),$gui)
GUICtrlCreatePic("c:\Program Files (x86)\AutoIt3\Examples\GUI\Merlin.gif", 0,0,47, 45)
WinSetTrans ( $pic, "", 50 )

GUISetState(@SW_SHOW,$pic)
Sleep(1e9)
GUISetState(@SW_SHOW,$gui)

While 1
    $msg = GuiGetMsg()
    Select
    Case $msg = $GUI_EVENT_CLOSE
        ExitLoop
    Case Else

    EndSelect
WEnd
Exit


Func Terminate()
    exit(0)
EndFunc

My problem is that I also want to make it transparent as well. When I use $WS_EX_TRANSPARENT and WinSetTrans ( $pic, "", 50 ), it appears transparent but the background comes back white.

UEZ suggested this code below using GDIPlus:

#include <GUIConstants.au3>
#include <GDIPlus.au3>
Global Const $STM_SETIMAGE = 0x0172
_GDIPlus_Startup()
$himg=_GDIPlus_ImageLoadFromFile("c:\Program Files (x86)\AutoIt3\Examples\GUI\Merlin.gif")
$hbmp=_GDIPlus_BitmapCreateHBITMAPFromBitmap($himg)
_GDIPlus_ImageDispose($himg)
$gui=GUICreate("test transparentpic", 200, 250)
$pic=GUICtrlCreatePic("",60,85,68,71)
_WinAPI_DeleteObject(GUICtrlSendMsg($pic,$STM_SETIMAGE,$IMAGE_BITMAP,$hbmp))
GUISetState(@SW_SHOW,$gui)

While 1
    $msg = GuiGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            _WinAPI_DeleteObject($hbmp)
            _GDIPlus_Shutdown()
        ExitLoop
    EndSelect
WEnd
Exit

I ran this above to see what happens and it brought the image up with white background and no transparency (which is what I thought it was going to do). Then I augmented as below:

#include <GUIConstants.au3>
#include <GDIPlus.au3>

HotKeySet("{END}", "Terminate")

Global Const $STM_SETIMAGE = 0x0172
_GDIPlus_Startup()
$himg=_GDIPlus_ImageLoadFromFile("c:\Program Files (x86)\AutoIt3\Examples\GUI\Merlin.gif")
$hbmp=_GDIPlus_BitmapCreateHBITMAPFromBitmap($himg)
_GDIPlus_ImageDispose($himg)

$gui=GUICreate("test transparentpic", 200, 250)
$gui=GUICreate("", 200, 250,0,0,$WS_POPUP,BitOr($WS_EX_LAYERED,$WS_EX_MDICHILD,$WS_EX_TRANSPARENT),$gui)
$pic=GUICtrlCreatePic("",60,85,68,71)
WinSetTrans ( $pic, "", 50 )

_WinAPI_DeleteObject(GUICtrlSendMsg($pic,$STM_SETIMAGE,$IMAGE_BITMAP,$hbmp))

GUISetState(@SW_SHOW,$gui)

While 1
    $msg = GuiGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            _WinAPI_DeleteObject($hbmp)
            _GDIPlus_Shutdown()
        ExitLoop
    EndSelect
WEnd

Func Terminate()
    exit(0)
EndFunc

trying to make it no background with transparency, but it still doesnt.  I dont understand why.

Any thoughts from anyone?

Thank you for your time guys,

Mason

The following would work.
 
Note that 
Child Windows can't have WS_EX_LAYERED till windows 7, ==> the problem in your first example
Note: windows 8 supports WS_EX_LAYERED with child windows.
 
Also WS_EX_TRANSPARENT doesn't allow a window to be transparent, it only allows click through, ie the underlying window would be receiving mouse input but an overlay of the given window would be shown.
 
You can set the transparency of WS_EX_LAYERED windows using functions(check example)
 
Example
#include-once
#include <GUIConstants.au3>
#include <GDIPlus.au3>
#include <WinAPISys.au3>


HotKeySet("{END}", "Terminate")

$GUI = GUICreate("", 147, 145, -1, -1, $WS_POPUP, $WS_EX_LAYERED)
$pic = GUICtrlCreatePic("", 0,0,147, 145)

Local Const $STM_SETIMAGE = 0x0172

_GDIPlus_Startup()
$himg=_GDIPlus_ImageLoadFromFile("c:\Program Files (x86)\AutoIt3\Examples\GUI\Merlin.gif")
$hbmp=_GDIPlus_BitmapCreateHBITMAPFromBitmap($himg)
_GDIPlus_ImageDispose($himg)

_WinAPI_DeleteObject(GUICtrlSendMsg($pic,$STM_SETIMAGE,$IMAGE_BITMAP,$hbmp))

GUISetState()

Local Const $iTransparency = 50
GUISetBkColor(0xABCDEF) ;this background color should be same as the trans color used in above function
_WinAPI_SetLayeredWindowAttributes($GUI,0xABCDEF, $iTransparency)

;~ GUISetState(@SW_SHOW,$gui)

While 1
    $msg = GuiGetMsg()
    Select
    Case $msg = $GUI_EVENT_CLOSE
        ExitLoop
    Case Else

    EndSelect
WEnd
Exit


Func Terminate()
    exit(0)
EndFunc

Awesome, thank you very much! Why use the GDIPlus stuff as opposed to not?  What advantages does it have?

In your case GDIPlus isn't required. The following would also do the same.

#include-once
#include <GUIConstants.au3>
#include <GDIPlus.au3>
#include <WinAPISys.au3>

HotKeySet("{END}", "Terminate")

$GUI = GUICreate("", 147, 145, -1, -1, $WS_POPUP, $WS_EX_LAYERED)
$pic = GUICtrlCreatePic("c:\Program Files (x86)\AutoIt3\Examples\GUI\Merlin.gif", 0,0,147, 145)

GUISetState()

Local Const $iTransparency = 50
GUISetBkColor(0xABCDEF) ;this background color should be same as the trans color used in above function
_WinAPI_SetLayeredWindowAttributes($GUI,0xABCDEF, $iTransparency)

;~ GUISetState(@SW_SHOW,$gui)

While 1
    $msg = GuiGetMsg()
    Select
    Case $msg = $GUI_EVENT_CLOSE
        ExitLoop
    Case Else

    EndSelect
WEnd
Exit


Func Terminate()
    exit(0)
EndFunc

The precise comparison, can only be given by an expert. I'm still very amateur in it. :P

      I was playing around with simple GUI creation.  I tend to like parameter driven coding (in prior life (years ago) as Clipper/FoxPro/dBase coder).  Just wanted to see what I could do with a GUI.

      For fun, I'm building an app that opens a webpage and refreshes it every 30 seconds.
      But once the script performs _IEAction($oIE, "refresh"), the GUI closes.

      Hi all,
      I have a button created with _GUICtrlButton_Create function. I know that this function returns a handle of button instead of an ID. So i have obtain control ID by calling _WinAPI_GetDlgCtrlID function. After that i have tried the GUICtrlSetBkColor function. But it didnt worked. Any suggestions will be appreciated. Thanks in advance. 
      Note : - The window which carries this button is not created with native gui create function. Instead, it is created with CreateWindowEx api function.

      Hi all,
      I am playing with _GUICtrlButton_Create function. How can i change this button's (or the entire form's) font ?. The in-built GUICtrlSetFont function is not working even when i convert the control handle to control ID with _WinAPI_GetDlgCtrlID ( ) function.  Do i need to use CreateFont api finction and send WM_SETFONT message ? Or is there any other easy and safe ways to do this ?. Thanks in advance.
      Note : This window is created by CreateWindowEx function, not by GUICreate function.
