Refresh GDIPlus graphic and button after minimize

5 posts in this topic

#1 ·  Posted

Hi

Under an old Malkey's script, posted in 2012, runs the refresh after minimizing a GDI+ graphic mask, but the button and the listview disappear.

How to refresh the GDI+ graphics and the normal buttons.

Excuse my bad English.

#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>
#include <GDIPlus.au3>
#include <GuiListView.au3>
Global $hBMPBuff, $hGraphicGUI

_Main()


Func _Main()
    Local $hGUI, $hEndCap, $hGraphic
    $hGUI = GUICreate("GDI+", 400, 300, -1, -1, BitOR($WS_MAXIMIZEBOX, $WS_MINIMIZEBOX))
    GUISetState()


    $CheckBox = GUICtrlCreateButton('Example', 10, 10, 70, 40)

    $ListV1= GUICtrlCreateListView('', 150, 10, 100, 100 )
    _GUICtrlListView_SetBkColor($ListV1, 0x00FFFF)
    _GUICtrlListView_SetTextBkColor($ListV1, 0x00FFFF)

    _GUICtrlListView_SetExtendedListViewStyle($ListV1, BitOR($LVS_EX_FULLROWSELECT, $LVS_EX_GRIDLINES))

    _GUICtrlListView_InsertColumn($ListV1, 0, "Column 1", 100)

    _GUICtrlListView_AddItem($ListV1, "Hello", 1)

    _GDIPlus_Startup()

    $hGraphicGUI = _GDIPlus_GraphicsCreateFromHWND($hGUI)
    $hBMPBuff = _GDIPlus_BitmapCreateFromGraphics(400, 300, $hGraphicGUI) ; Create bitmap the same size as the graphics of the GUI.
    $hGraphic = _GDIPlus_ImageGetGraphicsContext($hBMPBuff) ; Create graphics for bitmap, $hBMPBuff. (where the graphics is like the canvas of the bitmap)

    $hPen = _GDIPlus_PenCreate(0xFFFF0000, 2) ; Hex colour format 0xAARRGGBB - Alpha (transparency), Red, Green, Blue.
    $hEndCap = _GDIPlus_ArrowCapCreate(3, 6)
    _GDIPlus_PenSetCustomEndCap($hPen, $hEndCap)

    ; Draw arrows to bitmap
    _GDIPlus_GraphicsDrawLine($hGraphic, 10, 120, 390, 120, $hPen)
    _GDIPlus_PenSetWidth($hPen, 4)
    _GDIPlus_GraphicsDrawLine($hGraphic, 10, 150, 390, 150, $hPen)
    _GDIPlus_PenSetWidth($hPen, 6)
    _GDIPlus_GraphicsDrawLine($hGraphic, 10, 180, 390, 180, $hPen)

    _GDIPlus_GraphicsDrawImage($hGraphicGUI, $hBMPBuff, 0, 0) ; Draw bitmap to GUI (graphics).
    ; Loop until user exits

    GUIRegisterMsg(0x000F, "WM_PAINT") ;$WM_PAINT

    Do
    Until GUIGetMsg() = $GUI_EVENT_CLOSE

    ; Clean up resources
    _GDIPlus_ArrowCapDispose($hEndCap)
    _GDIPlus_PenDispose($hPen)
    _GDIPlus_GraphicsDispose($hGraphic)
    _GDIPlus_GraphicsDispose($hGraphicGUI)
    _WinAPI_DeleteObject($hBMPBuff)

    _GDIPlus_Shutdown()
EndFunc   ;==>_Main

Func WM_PAINT($hGUI, $iMsg, $wParam, $lParam)
    _GDIPlus_GraphicsDrawImage($hGraphicGUI, $hBMPBuff, 0, 0)
    _WinAPI_RedrawWindow($hGUI, 0, 0, $RDW_VALIDATE)
    Return 'GUI_RUNDEFMSG'
EndFunc   ;==>WM_PAINT

Thanks in advance.

I don't know whether this will work properly on WinXP machines but who cares...

Thanks for the quick response.

Autoit is a program Simply Exceptional and exceptionally simple, except when you put your hands on it.
I'm joking, you always have my greatest respect.
Correct if I'm wrong, you created a child gui as a layer, So, the update is the sum of the normal window and the secondary window that contains the graphics gdi .. no I did not understand, I must study it still long time.

In any case, 'GUIRegisterMsg (0x000F, "WM_PAINT")' is no longer needed.

Thanks again.

No, I haven't created a child window. $hChild enumerates all controls to exclude the regions from the graphic handle. In you case not necessarily needed but something which can be added if your objects crossing control positions.

WM_PAINT is needed in the case when you drag the window outside the desktop and back again.

You did me not even give me time to say I'm wrong, you're too fast, and I'm too old for these things.

I have seen that _GDIPlus_RegionCombineRect lists normal objects, in fact, if there are no objects, it generates an error.

However, if you want to take a look at an old project that goes very slowly, just to tell me if it's time lost or not.

I've always been a passionate about the button style etched of access, and I wanted to try to do it in autoit.

_GDIBStyle.au3

_GDIButton.au3

Demo.au3
