Repainting background image

8 posts in this topic

Hi everyone

See below my script. I have two problems/questions

1) Is there way to keep the image during the winanimate sequence when ` is pressed. Why does the image not restore after winanimate

2) Why does it inconsistently or have a delay redraw of the image when restored (tap Win+D a couple times) or winanimate it a few times to see what I mean.

Thanks for any advice.

If I have to guess on #1, WinAnimate doesn't play well with GDI+. You can at least redraw the window by adding MY_PAINT(1,2,3,4) after the animation sequence that restores the GUI.

Here is a non-flickering version with consistent repaints, and a few other nitpicky items fixed. The animation still messes with the bkgnd though.

#include <WindowsConstants.au3>

    Global $listviewGui = GUICreate("listviews", $reqwidth, $iY1, 10, @DesktopHeight - 185, $WS_POPUP, $WS_EX_TOOLWINDOW)

    Global $hGraphic = _GDIPlus_ImageGetGraphicsContext($hBMPBuff); Draw to this graphics, $hGraphic, being the graphics of $hBMPBuff

    $num = Int($reqwidth / $iX1)

        _GDIPlus_GraphicsDrawImageRect($hGraphic, $hImage1, $i * $iX1, 0, $iX1, $iY1)

Thanks wraithdu.

You made it work, repainting is now consistent. Always repaints after a restore and winanimate effect. I guess I won't be using the winanimate since as you say they don't play well together. It's easy enough to make your own effect anyway.

Thanks for your time on this.

Well I didn't 'say' they don't play well together... more of an observation. I did some more googling after my post, and didn't find any satisfactory solutions to that particular problem, except to learn that WinAnimate seems to create its own buffers for animation. I'm guessing those buffers do not have your GDI+ background, which is why it is blank when sliding. Maybe instead create a disabled pic control as the background to your GUI and paint somehow to that?

What I found out is that it has something to do with the styles of the GUI. If you set the style and ext. style to default it seems to be working.

Here another way:

#include <GDIPlus.au3>
#include <GUIConstantsEx.au3>
#include <WinAPI.au3>

OnAutoItExitRegister("ended")
HotKeySet("`","togglequick")
global $quickonoff=1, $view=1
Global $hImage,$listviewGui

_starting()

func _starting()
    Global    $reqwidth=1280
    _GDIPlus_Startup()
    Local $hImage1 = _GDIPlus_ImageLoadFromFile(@ScriptDir & "\metal_small.jpg")
    Local $iX1 = _GDIPlus_ImageGetWidth($hImage1)
    Local $iY1 = _GDIPlus_ImageGetHeight($hImage1)
    Local $hBitmap = DllCall($ghGDIPDll, "uint", "GdipCreateBitmapFromScan0", "int", $reqwidth, "int", $iY1, "int", 0, "int",  0x0026200A, "ptr", 0, "int*", 0)
    $hBitmap = $hBitmap[6]
    Local $hCtx = _GDIPlus_ImageGetGraphicsContext($hBitmap)
    For $i = 0 To $reqwidth Step $iX1
        _GDIPlus_GraphicsDrawImage($hCtx, $hImage1, $i, 0)
    Next
    Local $hBmp = _GDIPlus_BitmapCreateHBITMAPFromBitmap($hBitmap)
    _GDIPlus_ImageDispose($hImage1)
    _GDIPlus_BitmapDispose($hBitmap)
    _GDIPlus_GraphicsDispose($hCtx)
    Local $listviewGui = GUICreate("listviews", $reqwidth,$iY1, 10, @DesktopHeight-185);, $WS_POPUP, $WS_EX_TOOLWINDOW)
    Local $Pic = GUICtrlCreatePic("", 0, 0, $reqwidth, $iY1)
    GUICtrlSetState(-1, $GUI_DISABLE)
    GUISetState()
    Local Const $STM_SETIMAGE = 0x0172
    _WinAPI_DeleteObject(GUICtrlSendMsg($Pic, $STM_SETIMAGE, 0, $hBmp))
    _WinAPI_DeleteObject($hBmp)

EndFunc

while 1
    Sleep (1000)
WEnd


Func togglequick()
if $quickonoff=0 then
    _Win_xPlode(WinGetHandle($listviewGui,""), 300,"0x00040008")
    $quickonoff=1
Else
    _Win_xPlode(WinGetHandle($listviewGui,""), 300,"0x00050004")
    $quickonoff=0
EndIf
EndFunc


Func _Win_xPlode($hWnd, $tDel = 600, $ty="0x00040001")
  DllCall("user32.dll", "int", "AnimateWindow", "hwnd", WinGetHandle($hWnd,""), "int", $tDel, "long", $ty)
    If StringMid($ty,6,1) = 4 Then
      GUISetState(@SW_SHOW, $hWnd)
    Else
      GUISetState(@SW_Hide, $hWnd)
    EndIf
EndFunc   ;==>_Win_Plode


func ended()
    _GDIPlus_Shutdown()
    ConsoleWrite("ended")
EndFunc

In case it's of any interest, when you set the bitmap to the Pic using $STM_SETIMAGE the size of the pic is set by the size of the bitmap so setting the initial size of the pic is not necesary. It can prolong the life of several synapses to know that. Also, it means that if the pic has no image initially then you can set the size to 0, 0 and you don't get an unwanted black area waiting untill you set the image from a bitmap.
