richedit not working

[Fran]

I've tried various examples of richedit

and none of them do anything.

I want to create an Edit box with the Heading big and bold another sub-head smaller, but still bold and the rest of the text normal.

I am yet to find an example that actually works on my machine.

Maybe it's just a setting somewhere? Can anyone please assist?

Fran,

Like you, I find RichEdit controls quite difficult to deal with.

I wrote this little function a while ago to help me out - I hope you find it useful:

expandcollapse popup

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

$hGui = GUICreate("RichEdit Test", 320, 350)

$hRichEdit = _GUICtrlRichEdit_Create($hGui, "", 10, 10, 300, 220, BitOR($ES_MULTILINE, $WS_VSCROLL, $ES_AUTOVSCROLL))

GUISetState()

Sleep(2000)

; Increase by 12 pts, set to "bold" and colour red
_GUICtrlRichEdit_WriteLine($hRichEdit, "I am the BIG Heading!" & @CRLF, +12, "+bo", 0xFF0000)

Sleep(2000)

; Decrease by 6 pts, take away "bold" and colour Green
_GUICtrlRichEdit_WriteLine($hRichEdit, "I am the smaller Subheading!" & @CRLF, -6, "-bo", 0x00FF00)

Sleep(2000)

; Reduce by the other 6 pts, leave the attibutes alone and colour black
_GUICtrlRichEdit_WriteLine($hRichEdit, "I am normal text!" & @CRLF, -6, "", 0x000000)

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            GUIDelete()
            Exit
    EndSwitch

WEnd

Func _GUICtrlRichEdit_WriteLine($hWnd, $sText, $iIncrement = 0, $sAttrib = "", $iColor = -1)

    ; Count the @CRLFs
    StringReplace(_GUICtrlRichEdit_GetText($hWnd, True), @CRLF, "")
    Local $iLines = @extended
    ; Adjust the text char count to account for the @CRLFs
    Local $iEndPoint = _GUICtrlRichEdit_GetTextLength($hWnd, True, True) - $iLines
    ; Add new text
    _GUICtrlRichEdit_AppendText($hWnd, $sText & @CRLF)
    ; Select text between old and new end points
    _GuiCtrlRichEdit_SetSel($hWnd, $iEndPoint, -1)
    ; Convert colour from RGB to BGR
    $iColor = Hex($iColor, 6)
    $iColor = '0x' & StringMid($iColor, 5, 2) & StringMid($iColor, 3, 2) & StringMid($iColor, 1, 2)
    ; Set colour
    If $iColor <> -1 Then _GuiCtrlRichEdit_SetCharColor($hWnd, $iColor)
    ; Set size
    If $iIncrement <> 0 Then _GUICtrlRichEdit_ChangeFontSize($hWnd, $iIncrement)
    ; Set weight
    If $sAttrib <> "" Then _GUICtrlRichEdit_SetCharAttributes($hWnd, $sAttrib)
    ; Clear selection
    _GUICtrlRichEdit_Deselect($hWnd)

EndFunc

As you can see, you have to amend the size and attibutes of the text relative to the previous insertion - not what we are used to, so be careful here.

All clear?

As always! - thank you thank you thank you!!

[Fran]

Just one small problem... I can't hide the edit box with GUICtrlSetState()

[Melba23]

Fran,

As the RichEdit is not a native Autoit control, the GUICtrl* commands will not work on it.

You have to use WinSetState on it:

WinSetState($hRichEdit, "", @SW_HIDE)

Sleep(2000)

WinSetState($hRichEdit, "", @SW_SHOW)

P.S. Can I go and look at your other topic now or do we still have business here?

[Fran]

we're done here

Hi Melba, If I understand correctly, you script above count all lines alread printed and put the cursor after the last line printed, not re-printing everything from _GUICtrlRichEdit_Create?

_GuiCtrlRichEdit_SetSel($hWnd, $iEndPoint, -1)

Thanks ^^

This helped me.

Thanks Melba!
