PNG on Label

[CodyBarrett]

well i have a grid of labels 64 infact XD and i would like PNG pictures to be set on them... when i try its not working...

does $BS_BITMAP matter for .png?

is there another fileformat that is supported with a transparent background?

GUICtrlsetimage($Control, 'PNG.png') doesn't work at all... simply makes the square blank...

my Labels are Transparent is thats what is making it blank?

do i HAVE to use GDI+ (i would prefer it if i didn't have to even touch that area) to get the Width and Height?

does any one know what i should do? XD

You can use Yashied's Icons.au3 library to set the control's image/icon either by a handle to image or by a string representing the path to the file. Make sure that the label control doesn't contain $SS_CENTER style.

[CodyBarrett]

:| $SS_CENTER is taht screwing it up?

cause my labels style is this

$LStyle = BitOR ($SS_CENTER, $SS_CENTERIMAGE,$BS_BITMAP )

..and the fact that GUICtrlSetImage() is not for label controls and that png files are not supported.

[CodyBarrett]

well... is it possible for a picture to be on a Label?.... or do i have to place a Pics on top of everything cause that would complicate things greatly

[Authenticity]

Yes, perfectly valid and it's also very nice that you have the Icons.au3 UDF.

#include <Icons.au3>

Dim $hGUI = GUICreate('', 200, 200)
Dim $Label = GUICtrlCreateLabel('', 0, 0, 200, 200) ; Try once when $SS_CENTER is specified and watch the difference.

_SetImage($Label, @ScriptDir & '\image.png')

GUISetState()
Do
Until GUIGetMsg() = -3
GUIDelete()
Exit

[CodyBarrett]

okay LOL thanks man also is there a way to remove the style before setting the image?

Guictrlsetstyle ($Control, '') ? i dunno

[Authenticity]

#include <Constants.au3>
#include <StaticConstants.au3>
#include <WinAPI.au3>

$hLabel = GUICtrlGetHandle($Label)
_WinAPI_SetWindowLong($hLabel, $GWL_STYLE, BitAND(_WinAPI_GetWindowLong($hLabel, $GWL_STYLE), BitNOT($SS_CENTER)))

You can wrap it in a function to make it a bit clearer.

[CodyBarrett]

didn't know about Bitnot!

can't i just go Guictrlsetstate ($Control, Bitor (Bitnot ($SS_CENTER), Bitnot ($SS_CENTERIMAGE))) ?? that would be simpler

BTW i can't test any of this i'm at my cousins house

The problem is because I'm lacking enough knowledge of how to get the control style without using the _WinAPI_GetWindowLong() method and it doesn't exposes functionality like:

Func _WinAPI_GetWindowLong($hWnd, $iIndex)
    If Not IsHWnd($hWnd) Then $hWnd = GUICtrlGetHandle($hWnd)

; ...

You have to get the handle of the control to use this function. Another thing is that I think that AutoIt does the same but ORing the value of the current control style and thus ORing NOT 1 which is 0xFFFFFFFE is useless (sort of controlled assignment..) still not what you need. You can do it using a predefined style variable or something that is ORed with $SS_CENTER where needed.

OMG!!! thank you this is perfect! i actually just had enough time to test it out and WOW thank you lol

EDIT

well it works...

but also.. how do i remove the image so i can guictrlsetdata properly? cause when i remove the image the control won't accept text anymore

anyone know how i can remove the image and set some text on it?

#include <Constants.au3>
#include <GUIConstantsEx.au3>
#include <Icons.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>

Global $hGUI = GUICreate('Title', 200, 200)
Global $Label = GUICtrlCreateLabel('', 0, 0, 200, 150)
Global $hLabel = GUICtrlGetHandle($Label)
GUICtrlSetBkColor($Label, 0x602040)
Global $Button = GUICtrlCreateButton('Test', 65, 160, 70, 23)

_SetImage($Label, @ScriptDir & '\circle.png')

AdlibEnable('_Test', 1500)

GUISetState()
While 1
    Switch GUIGetMsg()
        Case $Button
            _WinAPI_SetWindowLong($hLabel, $GWL_STYLE, BitAND(_WinAPI_GetWindowLong($hLabel, $GWL_STYLE), BitNOT($SS_BITMAP)))
            GUICtrlSetState($Button, $GUI_DISABLE)
        Case $GUI_EVENT_CLOSE
            ExitLoop
    EndSwitch
WEnd
AdlibDisable()
GUIDelete()
Exit

Func _Test()
    GUICtrlSetBkColor($Label, Random(0x600000, 0x700000, 1))
EndFunc

After you'll click the button, in the next invocation of the adlib function you won't see the image. Passing anything other that an image handle in the _SetHIMage() function or just sending $STM_SETIMAGE with a value which is not resolves to a bitmap handle will remove the control completely.

well what i need is to get rid of the png... then be able to place Text into the now unused Label
