Problem with $WS_EX_COMPOSITED and $GUI_BKCOLOR_TRANSPARENT for label

[HeJake]

So, as the title says.

I am trying to make a gui with background image and without "sys" buttons and border ($WS_POPUP). Since i used image to make custom buttons and_lif with GetCursorInfo) to change image, changes was flickering. So for that i used $WS_EX_COMPOSITED. But! If you change label with transparent bg, they will overlap. Just for example:

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

$Form = GUICreate("Form", 420, 182, -1, -1, BitOR($WS_POPUP, $WS_EX_COMPOSITED))
GUISetBkColor(0x000000)
$Label = GUICtrlCreateLabel("", 150, 50, 15, 15)
GUICtrlSetFont($Label, 10)
GUICtrlSetColor($Label, 0xFFFFFF)
;GUICtrlSetBkColor($Label, $GUI_BKCOLOR_TRANSPARENT)
GUISetState(@SW_SHOW)

For $i = 1 To 100
GUICtrlSetData($Label, $i)
Sleep(10)
Next

After this, uncomment transparent bg and run again.

Any way to avoid this? Because i need to keep the label with transparent bg. (since bg image )

Or maybe there is another way to avoid flickering?

Also 1 more question, how do i make window move by clicking on body of it? I mean, game launchers (most of mmo) you able to move window just by holding mouse somewhere on the window (not only on the top as usual). I saw this somewhere, but can't find it

Don't update the label so often, your GUICtrlSetData is running every 10 ms, so the label is going to flicker.

[guinness]

Also use GUICtrlRead to check if the data is different to what you're updating the control with.

[HeJake]

Oh. My example was only an example to show you what's going on with label after update.

Of course my label doesn't update so often ( only few times, with conditions. )

Also there is only text. E.g: label was Hello, then label text was changed after 2 sec to Welcome, but the "Hello"

didn't clear, so that Welcome was "on" Hello. That is If i remove $GUI_BKCOLOR_TRANSPARENT from label, there is no probs, label updates well. But i need to keep transparency, because i have a label over an image. (It doesn't matter image or just color bg)

I used double buffering as i said for an image change ( like MouseOver, _ButtonHover, but with _lif and GUIGetCursorInfo ) it was flickering.

[BrewManNH]

$WS_CLIPCHILDREN and $WS_EX_COMPOSITED have the same value, so what you did was apply the first one to the standard Style setting, instead of setting $WS_EX_COMPOSITED to the extended style setting with your code above.

[HeJake]

I tried to use $WS_CLIPCHILDREN, same problem ( yeah because they're same ).Sorry for being kinda foolish. (maybe? )

And what to do then?

[BrewManNH]

So, to recap, it's not flickering, it's a redraw problem? Do you have an example of your script that demonstrates this with what it is you're trying to accomplish. Because all this one does is leaves a hole in the middle of the GUI with the numbers on top of each other.

[HeJake]

Okay, first try this:

#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>
#include <Misc.au3>
#Include <Icons.au3>
$Form = GUICreate("Form", 500, 300, -1, -1, BitOR($WS_POPUP, $WS_EX_COMPOSITED))
$BG = GUICtrlCreatePic(@ScriptDir & "\bg.jpg", 0, 0, 500, 300)
GUICtrlSetState($BG, $GUI_DISABLE)
$Inf = GUICtrlCreateLabel("", 216, 116, 600, 17)
GUICtrlSetBkColor($Inf, $GUI_BKCOLOR_TRANSPARENT)
GUICtrlSetFont($Inf, 10)
GUICtrlSetColor($Inf, 0xFFFFFF)
$cButton = GUICtrlCreatePic("", 440, 8, 35, 35)
_SetImage($cButton, @ScriptDir & "\closea.png")
$cButton2 = GUICtrlCreatePic("", 440, 8, 35, 35)
_SetImage($cButton2, @ScriptDir & "\closeb.png")
GUICtrlSetData($Inf, "Test text")
GUISetState(@SW_SHOW)

Sleep(2000)
GUICtrlSetData($Inf, "TEST TEXT")

While GUIGetMsg() <> $cButton
$aCursor = GUIGetCursorInfo($Form)
GUICtrlSetState($cButton2, _Iif(($aCursor[4] = $cButton2) And BitAND(GUICtrlGetState($cButton2), 16), $GUI_HIDE, _Iif($aCursor[4] <> $cButton And BitAND(GUICtrlGetState($cButton2), 32), $GUI_SHOW, 0)))
Sleep(10)
WEnd

Then with BitOR($WS_POPUP, 0)) And move mouse over button several times.

Buttons and bg attached.

What am I supposed to see on the button? Your PNG file for CloseA is corrupt btw.

[HeJake]

How it can be corrupted? Gosh.. Problem by problem.. I'm unlucky

Without $WS_EX_COMPOSITED button refresh sometime flick (u can see in that moment also default bg color of gui) and with it doesn't. About text, in both with and without $WS_EX_COMPOSITED its ok for you? With - Test text should be under TEST TEXT.

I only get that when you set the $WS_CLIPCHILDREN style, taking it out fixes that issue. I think part of the problem is that you're setting two buttons on top of each other rather than just changing the image.

[HeJake]

Yes, i was thinking about that too, but didn't tested yet.

And whats about my second question at the beginning? About moving whole window by holding left mbutton (as usual)? Since there is no borders

Nah, its anyway flickering for me on change..

About window move, found $SC_DRAGMOVE.

About text, still no solution. Tried also to make gui transparent, so you wont see gui background on image change in case without using $WS_CLIPCHILDREN ( or guistate, and actually strange that you able to see it, if the gui covered by image ) but it didn't work ( still see the gui background on flickering, as well flickering itself )

search for FunSkin

it deals with the replacing of icons of the titlebar including close, minimize and maximize

[HeJake]

Since i am using $WS_POPUP that is no needed thing. Anyway thank you BrewManNH, guinness and PhoenixXL for paying attention.

Found solution - $GUI_HIDESHOW
