[Solved] Auto-resizing RichEdit control

Recommended Posts

I know GUICtrlSetResizing() only works with the default autoit GUI controls, so I was wondering how I could use ControlMove() or something similar to accomplish the same thing?

Thanks :x

You have to handle the WM_SIZE message yourself unfortunately, and then use ControlMove (Or MoveWindow as I have). This means doing all the maths yourself as well, as you don't get the easy to use resizing flags.

This is a simple case with a 2px border on all sides, so the maths wasn't hard.


Global $hGUI = GUICreate("Testing WM_SIZE", 350, 250, -1, -1, BitOR($WS_THICKFRAME, $WS_POPUP, $WS_CAPTION, $WS_SYSMENU))
Global $hRichEdit = _GUICtrlRichEdit_Create($hGUI, "This is a test.", 2, 2, 346, 246, BitOR($ES_MULTILINE, $WS_VSCROLL, $ES_AUTOVSCROLL))

GUIRegisterMsg($WM_SIZE, "WM_SIZE")

While True
    $iMsg = GUIGetMsg()
        Case $iMsg = -3

Func WM_SIZE($hWnd, $iMsg, $wParam, $lParam)
    Local $iWidth = _WinAPI_LoWord($lParam)
    Local $iHeight = _WinAPI_HiWord($lParam)

    _WinAPI_MoveWindow($hRichEdit, 2, 2, $iWidth - 4, $iHeight - 4)

    Return 0
EndFunc   ;==>WM_SIZE

You can dispense with the maths if you are as lazy as I am and easily deal with any resizing method that is available for standard controls. Draw a label and set the sizeand position to be the same as the richedit at design time, and set the resizing for that as you want. Then, when you handle the resizing for the richedit you only have to copy the label size and position (using ControlGetPos). Just set the label to not visible of course.
