Gui dragbar

4 posts in this topic

I tried to use Melba23's GuiFrames, but I could not get it to work with richtext edit..

So coded my own version, and it works, but the issue is when I moved the dragbar, it flickers sometimes when there is a gui bkcolor specify...not a major issue, but an annoyance..

So I am looking for some feedback on how I might be able to do improve this

Thanks in advance

step887,

I have no problem using my UDF with a RichEdit if I do it like this: ;)

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

#include <GUIFrame.au3>

Global $fChanged = False

$hGUI = GUICreate("Test", 300, 600)

; Create a 1st level frame
$iFrame_A = _GUIFrame_Create($hGUI, 1)

GUISetState()

; Create the 2 edits
_GUIFrame_Switch($iFrame_A, 1)
$hTopFrame = _GUIFrame_GetHandle($iFrame_A, 1)
$aWinSize = WinGetClientSize($hTopFrame)
$hEdit1 = _GUICtrlRichEdit_Create($hTopFrame, "", 5, 5, $aWinsize[0] - 10, $aWinsize[1] - 10, BitOR($ES_MULTILINE, $WS_VSCROLL, $ES_AUTOVSCROLL))
_GUIFrame_Switch($iFrame_A, 2)
$hBottomFrame = _GUIFrame_GetHandle($iFrame_A, 2)
$aWinSize = WinGetClientSize($hBottomFrame)
$cEdit2 = GUICtrlCreateEdit("", 5, 5, $aWinsize[0] - 10, $aWinsize[1] - 10, BitOR("Ox503310C4", $WS_VSCROLL))

_GUIFrame_ResizeSet(0)

; Register the SIZE message to look for the seperator bar moving
GUIRegisterMsg($WM_SIZE, "_WM_SIZE")

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
    ; See if the frame has been resized
    If $fChanged = True Then
        ; Clear the flag
        $fChanged = False
        ; Resize the RichEdit
        $aWinSize = WinGetClientSize($hTopFrame)
        WinMove($hEdit1, "", 5, 5, $aWinsize[0] - 10, $aWinsize[1] - 10)
    EndIf
WEnd

Func _WM_SIZE($hWnd, $iMsg, $wParam, $lParam)
    ; Do the normal resizing frame resizing
    _GUIFrame_SIZE_Handler($hWnd, $iMsg, $wParam, $lParam)
    ; Set the flag if the top frame has been resized
    If $hWnd = $hTopFrame Then
        $fChanged = True
    EndIf
EndFunc

Does that help? :)

As to the flickering, I have been trying to solve that problem for ages without success. Please let me know if you ever find a solution. :D

Thanks Melba, I try to do it that way (i think.. that was a couple days ago), but I could never get the richtext edit to appear..

And if you can not get the flickering to disappear then I sure I will not be able too.

Melba,

So I think I found the answer.. I stumbled on to this

http://www.catch22.net/tuts/flicker-free-drawing

Basically, when you set the gui background and then you put a control on top, each time you resize, windows has to redraw the background color, which causes the flicker

So what I did in previous example, I did not set GUISetBkColor, instead I created labels for the borders and now I do not see the flicker..
