Richedit Control Options

[StMaSi]

Two questions...

When presenting a form containing a richedit control, is there any way to make the displayed text, within said richedit control, non-selectable?

In addition, is there any way to hide the vertical line cursor, within said richedit control?

Thanx.

StMaSi,

WinSetState($hRichEdit, "", @SW_DISABLE) should do both for you.

Well, that does, in fact, disable the control, but the background now turns from white to grey and the text is greyed out as well. Is there a way to have the control disabled in this manner, but to restore the background and text color to what they were prior to disabling the control?

StMaSi,

How about a mask like this:

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

Global $hGUI, $hGUI_Mask

Func Example()
    Local $hRichEdit, $iMsg
    $hGui = GUICreate("Example (" & StringTrimRight(@ScriptName, StringLen(".exe")) & ")", 320, 350, -1, -1)
    $hRichEdit = _GUICtrlRichEdit_Create($hGui, "This is a test.", 10, 10, 300, 220, BitOR($ES_MULTILINE, $WS_VSCROLL, $ES_AUTOVSCROLL))
    _GUICtrlRichEdit_AppendText($hRichEdit, @CRLF & "This is more text")

    $cButton = GUICtrlCreateButton("Test", 10, 300, 80, 30)

    GUISetState(@SW_SHOW)

    $aGUI_Pos = WinGetPos($hGUI)
    $hGUI_Mask = GUICreate("Mask", 300, 220, 0, 0, BitOR($WS_POPUP, $WS_BORDER), 0, $hGUI)

    WinMove($hGUI_Mask, "", $aGUI_Pos[0] + 10, $aGUI_Pos[1] + 35)
    GUISetState(@SW_SHOWNOACTIVATE, $hGUI_Mask)
    WinSetTrans($hGUI_Mask, "", 100)

    ; Look for the main GUI moving
    GUIRegisterMsg($WM_MOVE, "_WM_MOVE")

    While True
        $iMsg = GUIGetMsg()
        Select
            Case $iMsg = $GUI_EVENT_CLOSE
                _GUICtrlRichEdit_Destroy($hRichEdit) ; needed unless script crashes
                ; GUIDelete()   ; is OK too
                Exit
            Case $iMsg = $cButton
                ConsoleWrite("Hit" & @CRLF)
        EndSelect

        If _WinAPI_GetFocus() = $hRichEdit Then
            _WinAPI_SetFocus($hGUI_Mask)
        EndIf

    WEnd

EndFunc   ;==>Example

Func _WM_MOVE($hWnd, $iMsg, $wParam, $lParam)
    ; If the main GUI moves
    If $hWnd = $hGUI Then
        ; Move the child to follow

Unfortunately, that hides my entire form.

[Melba23]

StMaSi,

No it does not, it only masks the RichEdit control - if it does more than that then you have messed up the sizing code. Please post what you are using and I will take a look.

When I add the...

WinSetState($RICHEDITCONTROL1, "", @SW_DISABLE)

The richedit control is greyed out. However, when I attempted to incorporate your mask code, the entire form would not display. Like you said, I must be attempting to incorporate your code improperly (it's not currently within this code). Can you assist with the incorporation?

Thanx.

[InunoTaishou]

Here's something a little simpler. I used this when I was working on a console application and wanted to use a rich edit

Creating a label over the area where the richedit control is and setting the label's backcolor to $GUI_BKCOLOR_TRANSPARENT

expandcollapse popup

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

Global $hGUI

Example()

Func Example()
    Local $hRichEdit, $iMsg
    $hGui = GUICreate("Example (" & StringTrimRight(@ScriptName, StringLen(".exe")) & ")", 320, 350, -1, -1)
    $lblMask = GUICtrlCreateLabel("", 10, 10, 300, 220)
    GUICtrlSetBkColor($lblMask, $GUI_BKCOLOR_TRANSPARENT)
    $hRichEdit = _GUICtrlRichEdit_Create($hGui, "This is a test.", 10, 10, 300, 220, BitOR($ES_MULTILINE, $WS_VSCROLL, $ES_AUTOVSCROLL))
    _GUICtrlRichEdit_AppendText($hRichEdit, @CRLF & "This is more text")
    ; Prevent the richedit from being entered using the 'Tab' key
    _WinAPI_SetWindowLong($hRichEdit, $GWL_STYLE, BitAND(_WinAPI_GetWindowLong($hRichEdit, $GWL_STYLE), BitNOT($WS_TABSTOP)))

    $cButton = GUICtrlCreateButton("Test", 10, 300, 80, 30)
    ; Set the button to focus so the richedit control doesn't have focus (having focus would let someone type in it)
    GUICtrlSetState($cButton, $GUI_FOCUS)

    GUISetState(@SW_SHOW)

    While True
        $iMsg = GUIGetMsg()
        Select
            Case $iMsg = $GUI_EVENT_CLOSE
                _GUICtrlRichEdit_Destroy($hRichEdit) ; needed unless script crashes
                ; GUIDelete()   ; is OK too
                Exit

InunoTaishou,

Great idea and much simpler than mine. I think I became fixated on using a child GUI because I had been working on one earlier on the day.

M23

[StMaSi]

When utilizing the following two bits of code from InunoTaishou, the richedit control remains active (not greyed out) and the cursor is not flashing because the focus is on the label:

...
_WinAPI_SetWindowLong($RICHEDITCONTROL1, $GWL_STYLE, BitAND(_WinAPI_GetWindowLong($RICHEDITCONTROL1, $GWL_STYLE), BitNOT($WS_TABSTOP)))
...
GUICtrlSetState($LABEL1, $GUI_FOCUS)
...

However, the richedit control is still selectable...a user can click into it, which exposes the cursor and/or double-click into it and highlight text within. Short of utilizing individual labels for the information that would be contained within one richedit control, is there no other way to "lock down" (for lack of a better term) the richedit control, but avoid disabling it (the graying out)?

Thanx again for all your help, peeps.

Really? I have just been trying to do just that and I cannot get at the RichEdit at all. How did you manage it?

[StMaSi]

Perhaps my mouse-clicking is more powerful than yours?

Create the RichEdit in a child window and disable the child window:

I'm going to guess and say that the label you created over the richedit control is not actually over the richedit control. So you're just clicking on the richedit.

Do this and see where your label is actually at

GUICtrlSetBkColor($LABEL1, 0xFF0000)
