Scrollable Label

10 posts in this topic

hmm,.. dont know if this prob has been ever solved - but i looked and searched a long time in this forum - but dont found anything,..

OK,..my problem:

i have a .txt file with a large text. i want to scroll in this label - but it doesnt work - why?

CODE

$text=FileRead("startseite.txt")

GUICtrlCreateLabel ($text, 230, 135, 530,440,$ES_AUTOVSCROLL+$WS_VSCROLL)

hmmm,...

i solved it with an inputbox:

CODE

$text=FileRead("startseite.txt")

GUICtrlCreateEdit ($text, 230, 135, 510,440,BitOR($ES_READONLY, $WS_VSCROLL, $ES_MULTILINE))

can i deactivate the Cursor?

There's no getting rid of the cursor, and I don't think labels can ever scroll in the first place, though you can put scrollbars on them visually. Even Windows Update on 2000 and XP uses a read-only edit box for the installation log, and the cursor is indeed visible. Or next time you use one of those "wizard" installers, check the license agreement page and I'll bet you can see a cursor if you click in the text area (you might also see it in the list of files that are being installed). It's really not a big deal, and it also allows you to select and copy the text.

I was talking about the text cursor. You know, the little blinking vertical line that marks your place in an edit box. I think it would be quite odd to remove the mouse cursor from Aekschnuschi's edit box (especially since it would make manipulating the scrollbars rather difficult).

There's no getting rid of the cursor...

#include <GUIConstants.au3>

$hidden = False

$gui = GUICreate('My Hide Caret', 200, 200)
$edit = GUICtrlCreateEdit('Here is my edit box with no caret!', 50, 50, 100, 100, $ES_READONLY)

GUISetState()

While 1
    If WinActive('My Hide Caret') And Not $hidden Then
        DllCall('user32.dll', 'int', 'DestroyCaret')
        $hidden = True  ;  this so it's not called over and over
    EndIf
    If Not WinActive('My Hide Caret') Then $hidden = False
    If GUIGetMsg() = $GUI_EVENT_CLOSE Then Exit
WEnd

Heh, I guess you showed him. :shocked:

I would have said the same as him though, never thought you'd be able to get rid of the caret.

Haha I didn't figure it out to show him up. I tried to find the answer to challenge myself. :shocked:

DestroyCaret, eh? Never would have thought. Looking at MSDN it appears you're only supposed to call it when your window is about to lose keyboard focus, so I guess this is sort of an unintended bonus. Might even come in handy for a project I'm working on right now. Nice work!

Well, there actually are Hide/ShowCaret functions. I was just destroying. I guess this is more 'proper.' :shocked:

#include <GUIConstants.au3>

$hidden = False

GUICreate('My Hide Caret', 220, 180)
$edit = GUICtrlCreateEdit('Here is my edit box caret example!', 20, 20, 180, 100, $ES_READONLY)
$btn1 = GUICtrlCreateButton('Show Caret', 20, 140, 80, 26)
$btn2 = GUICtrlCreateButton('Hide Caret', 120, 140, 80, 26)

GUISetState()

While 1
    $msg = GUIGetMsg()
    Switch $msg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $btn1
            DllCall('user32.dll', 'int', 'ShowCaret', 'hwnd', '')
            GUICtrlSetState($edit, $GUI_FOCUS)
        Case $btn2
            GUICtrlSetState($edit, $GUI_FOCUS)
            DllCall('user32.dll', 'int', 'HideCaret', 'hwnd', '')
    EndSwitch
WEnd
