RichEdit On Graphic ... can flashing be stopped?

2 posts in this topic

I had the bright idea to place some rich edit text on top of a graphic. Technically, it works ... but it flashes terribly when scrolled ... and even a little when typing into the field. I've tried placing a white rectangle under the text, but that didn't help. Here's my test script and the graphic file. If you place some paragraphs from www.lipsum.com into the field and then use the scroll bar, the flashing is dramatic.

; Test of Rich Text on graphic
;
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GuiRichEdit.au3>
#Include <GuiScrollBars.au3>
#include <ScrollBarConstants.au3>
$GUI=GUICreate("Rich Text On Graphic",900,800,60,60);,$WS_POPUP,$WS_EX_LAYERED+$WS_EX_TOOLWINDOW)
GUICtrlCreatePic(@ScriptDir & "\GraphicBackground.bmp",40,40,800,700)
GUICtrlSetState(-1,$GUI_DISABLE)
$MainRich = _GUICtrlRichEdit_Create($GUI, "", 90, 90, 680, 600, BitOR($ES_MULTILINE, $WS_VSCROLL), 0x20) ; $ES_READONLY, $ES_WANTRETURN,
_GUICtrlRichEdit_SetBkColor(-1,0xFFFFFF)
_GUICtrlRichEdit_SetFont($MainRich, 14, "Franklin Gothic Medium")
_GUIScrollBars_ShowScrollBar($MainRich, $SB_VERT, True)
GUISetState()
While 1
    $nMsg = GUIGetMsg()
    Select
        Case $nMsg = $GUI_EVENT_CLOSE
_GUICtrlRichEdit_Destroy($MainRich)
            Exit
    EndSelect
WEnd

Is there some setting or technique that can make it stable?

Thanks for any help or advice.

Did you try Googling on it?

I found a few interesting results

RichEdit with transparent background in Delphi? Hell yes!

See through Rich Edit control

Try porting one to AutoIt and see how it goes.
