clicking maximize button max height and max width

[ludocus]

When I click the maximize button, my gui automaticly resizes to @DesktopWidth and @DesktopHeight

is it possible to make it only resize to like, 300 width and 400 height?

because I cant figure out how..

I knoew how to make it maximize to my own size, but then the maximize button does not get replaced bye the restore button..

This 'maximises' to some maximum and prevents you resizing beyond the max size by dragging. (Or below the minimum size.)

#include <GUIConstantsEx.au3>
#include <windowsconstants.au3>
Opt("GUIEventOptions", 1);<-----------------important
;Const $WM_GETMINMAXINFO = 0x24
Global $maxht = 600, $maxwid = 600, $minht = 100, $minwid = 100;<-------size limits

$gui = GUICreate("Test GUI", 500, 500, -1, -1, BitOR($GUI_SS_DEFAULT_GUI, $WS_SIZEBOX, $WS_MAXIMIZEBOX))
GUISetState(@SW_SHOW)

GUIRegisterMsg($WM_GETMINMAXINFO, "MY_WM_GETMINMAXINFO");stops resizing beyond limits
Global $wp = wingetpos($gui)

While 1
    $msg = GUIGetMsg()
    Switch $msg
        Case $GUI_EVENT_CLOSE
            ExitLoop
        Case $GUI_EVENT_MAXIMIZE;<--deals with clicking the maximize button
            WinMove($gui, "", $wp[0], $wp[1], $maxwid, $maxht)
    EndSwitch
WEnd

Func MY_WM_GETMINMAXINFO($hWnd, $msg, $wParam, $lParam)
    $wp = WinGetPos($gui)
    ConsoleWrite($wp[0] & ', ' & $wp[1] & @CRLF)
    $minmaxinfo = DllStructCreate("int;int;int;int;int;int;int;int;int;int", $lParam)
    DllStructSetData($minmaxinfo, 7, $minwid); min X
    DllStructSetData($minmaxinfo, 8, $minht); min Y
    DllStructSetData($minmaxinfo, 9, $maxwid + 1); max X
    DllStructSetData($minmaxinfo, 10, $maxht + 1); max Y
    Return 0
EndFunc ;==>MY_WM_GETMINMAXINFO

The disadvantage of this is that you don't get the maximize button changing to a restore button. I don't know how to fix that.

EDIT:changed declaration of $wp so the first time window maximized it behaves the same as other times.

there's things to fix :

- when window is minimized and you click on it in taskbar then height and width change to DesktopHeight and @DesktopWidth

- when maximized, it's still possible to move it...

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

Opt('MustDeclareVars', 1)
Local $v_msg,$h_ButtonQuit,$h_myGui
Local $n_MaxWidth = @DesktopWidth*2/3
Local $n_MaxHeight = @DesktopHeight*2/3

$h_myGui = GUICreate("Test maximize",200,50,-1,-1, $WS_MINIMIZEBOX + $WS_CAPTION + $WS_POPUP + $WS_SYSMENU +$WS_MAXIMIZEBOX)
$h_ButtonQuit = GUICtrlCreateButton("&Quit", 10, 10,80,30)
GUISetState()

While 1
    $v_msg = GUIGetMsg()
    Select
        Case $v_msg = $GUI_EVENT_CLOSE
            ExitLoop
        Case $v_msg = $h_ButtonQuit
            ExitLoop            
        Case $v_msg = $GUI_EVENT_MAXIMIZE
            WinMove($h_myGui,"",0,0,$n_MaxWidth,$n_MaxHeight)
    EndSelect
WEnd

ok, thats how far I got by myself to..

but when it is maximized, the maximize button does not change into a restore size button.. how do I do that?

This is far from perfect but it demonstrates an idea which works.
