Simple .png image in button ctrl? Help!

2 posts in this topic

#1 ·  Posted (edited)

Greetings!

I'd like to create button with .png image on it. Yet I cannot make the thing to work properly :)

I've started from GuiCtrlSendMsg function which works perfect to set .png images in GuiCtrlPic controls... Yet it can't create transparent background with button controls ;)

Below it's the code I've got so far: (it might ask u for dling one small png image, so u could see the problem)

#include <GdiPlus.au3>

$hGui = GUICreate('')
$hButton = GUICtrlCreateButton('', 10, 10, 128, 128, 0x0080) ; BS_BITMAP style
$hStaticLabel = GUICtrlCreatePic('', 10, 150, 128, 128) ; no style needed




; I will Download PNG Image for you... I hope it's okay...
If Not FileExists('plus.png') Then
    ; I will Download PNG Image for you... I hope it's okay...
    If MsgBox(4, 'Question for you my dear...', 'Is it OKAY to download small png image from google images?') = 6 Then
        InetGet('http://www.smyku.pl/img/plus.png', 'plus.png')
    Else
        Exit MsgBox(0, '', 'Bye bye then <img src='http://www.autoitscript.com/forum/public/style_emoticons/<#EMO_DIR#>/sad.png' class='bbc_emoticon' alt=':(' />')
    EndIf
EndIf





_GDIPlus_Startup()

$hPngImage = _GDIPlus_ImageLoadFromFile('plus.png')

Global $iARGB = 0xFF000000 ; you can manipulate with that, making it white, yellow, blue, etc. etc. backgrounded... But not transparent <img src='http://www.autoitscript.com/forum/public/style_emoticons/<#EMO_DIR#>/sad.png' class='bbc_emoticon' alt=':(' />
$hBitmapHandle = _GDIPlus_BitmapCreateHBITMAPFromBitmap($hPngImage, $iARGB)

; Setting image to a Static / Label - works FINE, background is fully transparent
GUICtrlSendMsg($hStaticLabel, 0x0172, 0,  $hBitmapHandle) ; 0x0172 == STM_SETIMAGE msg

; Setting image to a Button - works _NOT_AT_ALL_
GUICtrlSendMsg($hButton, 0x0F7, 0, $hBitmapHandle)  ; 0x0F7 == BM_SETIMAGE msg






GUISetState()

Do
    $msg = GUIGetMsg()
    Switch $msg
        Case -3
            _WinAPI_DeleteObject($hBitmapHandle) ; cleaning resources
            _GDIPlus_ImageDispose($hPngImage)   ; x2
            Exit
        Case $hButton
            MsgBox(0, "I'm a button", _
                            "It's _NOT_ a racist thing... I just don't want to be black any more <img src='http://www.autoitscript.com/forum/public/style_emoticons/<#EMO_DIR#>/sad.png' class='bbc_emoticon' alt=':(' />" & _
            @CRLF & _
            @CRLF & _
                            "NOT white neither... I just want to be _TRANSPARENT_! Can you help me...? <img src='http://www.autoitscript.com/forum/public/style_emoticons/<#EMO_DIR#>/sad.png' class='bbc_emoticon' alt=':(' />" )
    EndSwitch
Until False

Maybe you will know how to make this code work...?

It's the same method _GuiCtrlButton_SetImage() function is using...

For Buttons works only with .bmp / .ico

For Pics works with everything.

How come?

Best regards,

hoping for your help,

I already had that solution in the example forum, I will search for it.

EDIT: This was only for gui.

But you can make a little gui where you can click on.

It was somewhere on the forum, You saw a heart and a windows gray logo, when you clicked it stopped blinking.

I will search further

Take a look at this.

And here

And here is your solution I think:
