3 posts in this topic

#1 ·  Posted (edited)

In this demo example GUI window can be maximized/restored programatically by:

- system menu

- button

- hotkey F11

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

$gui = GUICreate("Maximize/restore demo", 300, 200, -1, -1, BitOr($GUI_SS_DEFAULT_GUI, $WS_MAXIMIZEBOX, $WS_SIZEBOX))
$max_id = GUICtrlCreateDummy()
$b1 = GUICtrlCreateButton("maximize/restore", 10, 10, 120, 20 )
GUICtrlCreateLabel("F11: maximize/restore", 10, 50, 120, 20 )
GUISetState(@SW_SHOW, $gui)
 
Dim $Form1_AccelTable[1][2] = [["{F11}",$max_id]]
GUISetAccelerators($Form1_AccelTable, $gui)
 
Do
    $msg = GUIGetMsg()
    If $msg = $max_id Or $msg = $b1 Then Maximize()
Until $msg = $GUI_EVENT_CLOSE
 
Func Maximize()
    If BitAnd(WinGetState($gui), 32) = 0 Then ; not maximized
        _SendMessage($gui, $WM_SYSCOMMAND, $SC_MAXIMIZE, 0)
    Else
        _SendMessage($gui, $WM_SYSCOMMAND, $SC_RESTORE, 0)
    EndIf
    Return $GUI_RUNDEFMSG
EndFunc

EDIT: fixed list of includes for (standard) latest beta

Which version of AutoIt are you using? As some constants aren't available e.g. you're using GUIConstants.

This works on the latest beta of AutoIt.

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

Local $hGUI
Local $iButton, $iControl

$hGUI = GUICreate("Demo - by Zedna", 300, 200, -1, -1, BitOR($GUI_SS_DEFAULT_GUI, $WS_MAXIMIZEBOX, $WS_SIZEBOX))
$iControl = GUICtrlCreateDummy()
$iButton = GUICtrlCreateButton("Maximise/Restore", 10, 10, 120, 35)
GUICtrlCreateLabel("F11: Maximise/Restore", 15, 50, 120, 35)
GUISetState(@SW_SHOW, $hGUI)

Local $aHotKey[1][2] = [["{F11}", $iControl]]
GUISetAccelerators($aHotKey, $hGUI)

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit

        Case $iControl, $iButton
            Maximize()

    EndSwitch
WEnd

Func Maximize()
    Local Const $SC_MAXIMIZE = 0xF030, $SC_RESTORE = 0xF120
    Local $sState
    If BitAND(WinGetState($hGUI), 32) = 0 Then ; Not Maximised
        $sState = $SC_MAXIMIZE
    Else
        $sState = $SC_RESTORE
    EndIf
    Return _SendMessage($hGUI, $WM_SYSCOMMAND, $sState)
EndFunc   ;==>Maximize

Sorry for inconvenience and thanks for correction.

I use Autoit 3.3.7.18 but with modified copy of GUIConstants.au3

Explanation is here:
