GUICtrlCreatePic and GIF transparency

[Pieter]

I want to display a GIF image (see attachment) that uses transparency. However, the transparent part of the image has been replaced with the color black. I tried to fix this like so (as described in the manual):

$status_icon = GUICtrlCreatePic("img_src\iPodCALsync_aboutico.gif", 8, 8, 65, 64, BitOR($SS_NOTIFY,$WS_GROUP))
GUICtrlSetBkColor(-1, $GUI_BKCOLOR_TRANSPARENT)

Unfortunately, this code doesn't fix the problem. Is there anything else I should try?

[Pieter]

And changing the background color to white

GUICtrlSetBkColor($status_icon, 0xFFFFFF)

doesn't work either.

This doesn't do what I thought it would do. I need the transparent part to have the color of the GUI. Is there a way to fetch the GUI background color string? (I don't want the window to look ugly if people don't use the default XP theme.)

it is always good to have a complete working script.

I just add what is described in example 2 of the help and tha's fine;)

#include <GUIConstants.au3>

$pic=GUICreate("", 96, 96, 100, 100,$WS_POPUP,$WS_EX_LAYERED)

$status_icon = GUICtrlCreatePic("transparent.gif", 0, 0, 96, 96, BitOR($SS_NOTIFY,$WS_GROUP))
GUICtrlSetBkColor(-1, $GUI_BKCOLOR_TRANSPARENT)
GUISetState()

do
    $msg = GUIGetMsg()
until $msg = $GUI_EVENT_CLOSE
Exit

Why does having the form set to $WS_POPUP make the gif background transparency work? The background should be transparent even if it's not $WS_POPUP, but as Pieter says, it's black.

Also, if the gif background is transparent why does that also make the form transparent in that area?

I think this behaviour is wrong.

Right now, this is what it looks like:

With 'transparent', I mean something like this (manipulated screenshot):

How can I accomplish this?

You can do it like by having another form behind which is not set as $WS_POPUP

#include <GUIConstants.au3>
$p0c=GUICreate("", 190, 160, 100, 100)
GUISetState()
$pic=GUICreate("dsfvsds", 196, 196, 100, 100,$WS_POPUP,$WS_EX_LAYERED);,$WS_POPUP,$WS_EX_LAYERED)

$status_icon = GUICtrlCreatePic("transparent.gif", 10, 10, 96, 96, BitOR($SS_NOTIFY,$WS_GROUP))
GUICtrlSetBkColor(-1, $GUI_BKCOLOR_TRANSPARENT)
GUISetState()

do
    $msg = GUIGetMsg()
until $msg = $GUI_EVENT_CLOSE
Exit

But as I said in my last post, I think the behaviour is wrong and you shouldn't need to do things like this.

You need to define the background so the multiple windows as described in the example2 with do it.
