Force another application in windowed fullscreen mode.

[gigi1]

Hi,

i'm trying to make an application to transform existing windows into "windowed fullscreen".

For example, i want to achieve with other applications what can be done in autoit with this code:

GUICreate("asd", @DesktopWidth, @DesktopHeight, 0, 0, $WS_POPUP)
GUISetState()
Sleep(3000)

So far i've searched the forums and found the _WinApi_SetWindowLong() function, but if i do this:

$hwnd = WinGetHandle("[Class:Notepad]")
WinMove($hwnd, "", 0, 0, @DesktopWidth, @DesktopHeight)
_WinAPI_SetWindowLong($hwnd, $GWL_STYLE, $WS_POPUP)

then weird things will happen: Notepad will go in windowed fullscreen mode, but the taskbar will still be there, and the whole notepad window will be inactive. Moreover if you click somewhere in the notepad window the click will go below it (ex.: it will launch desktop applications if you happen to click where their icon is).

Any ideas on how to do it?

Thanks

You need to remove some styles which won't affect the program itself and update the window, see

Br, FireFox.

thank you very much

okay so i tested it and came up with this:

(assuming notepad is running)

#include <Constants.au3>
#include <WinAPI.au3>
#include <WindowsConstants.au3>

$width = @DesktopWidth
$height = @DesktopHeight
$hWnd = WinGetHandle("[CLASS:Notepad]")
If @error Then MsgBox(0, "error", "error")
$iStyle = _WinAPI_GetWindowLong($hWnd, $GWL_STYLE)
$iStyle = BitOR($iStyle, $WS_POPUP)
_WinAPI_SetWindowLong($hWnd, $GWL_STYLE, $iStyle)
_WinAPI_SetWindowPos($hWnd, $HWND_TOP, 0, 0, $width, $height, $SWP_FRAMECHANGED)

However, this doesn't change the window style at all.

Moreover, it will not place the window on top of the taskbar like the $WS_POPUP does for native autoit GUIs. (i know i could do it using the flag $HWND_TOPMOST instead of HWND_TOP, but then it's not possible to alt-tab to other applications).

edit: change from code to autoit code, didn't see it in the first place. code highlighting is nice

#include <Constants.au3>
#include <WinAPI.au3>
#include <WindowsConstants.au3>

Local Const $hWnd = WinGetHandle("[CLASS:Notepad]")
If @error Then MsgBox(0, "error", "error")

Local $iStyle = _WinAPI_GetWindowLong($hWnd, $GWL_STYLE)

$iStyle = BitOR(BitXOR($iStyle, $WS_MINIMIZEBOX, $WS_MAXIMIZEBOX, $WS_CAPTION, $WS_BORDER, $WS_SIZEBOX), $WS_POPUP)

_WinAPI_SetWindowLong($hWnd, $GWL_STYLE, $iStyle)
_WinAPI_SetWindowPos($hWnd, $HWND_TOPMOST, 0, 0, @DesktopWidth, @DesktopHeight, $SWP_FRAMECHANGED)

thanks again, so simple, i feel so nab >_<

but... its not working for many applications, too, (example: windows media player)

I wanted to make my own window manager, but it seems that i won't be able to fullscreen a lot of applications, and many others just glitch on forced styles.

You can, make a list of "non-wanted" styles and remove them only if they are present.
