Hi,

I am trying to open full screen window from my application. Unfortunately only main window is able to do this, all other windows aren't.
Do you have any idea how to convince window manager (metacity? ubuntu 10.04 and 12.04), to let all windows go fullscreen?

Test code:
#include <CtrlLib/CtrlLib.h>

using namespace Upp;

static int i = 0;

struct MyAppWindow : TopWindow {
	
	Label l;

    virtual void LeftDown(Point pos, dword flags) {
        MyAppWindow().Run();
    }

    MyAppWindow() {
        Title("Fullscreen");
        FullScreen();
        l.SetLabel(Format("\1[= Window %d&Click to open next window]", ++i));
        l.SizePos();
        Add(l);
    }
};


GUI_APP_MAIN

{
	MyAppWindow().Run();
}

fullscreen applies to the window it is executed on.

So to get it for all screens you have to add it to all you're dialogs.

Why do you think I didn't apply Fullscreen to all dialogs? Take a look at the example code. In ubuntu 12.04 I had to add also Sizeable(), otherwise even first window wasn't full screen (it was maximized).

Hi Zbych,

I have the same problem on all my gtk base distributions (Ubuntu 12.10 (In this case fullscreen completely dosen't work!) & Xubungu 12.10). On Kubuntu 12.10 your example code works very well.

Sincerely,
Klugier

Are you saying this is a Gnome issue?

Try OpenMain(). It is possible that WM disallows it for dependent windows.

I was fighting with this also.

I got this working in debian (with gnome classic) and Windows

#include <CtrlLib/CtrlLib.h>

using namespace Upp;

#define LAYOUTFILE <MaximizeTest/MaximizeTest.lay>
#include <CtrlCore/lay.h>

class MaximizeTest : public WithMaximizeTestLayout<TopWindow> {
public:
	typedef MaximizeTest CLASSNAME;
	MaximizeTest()
	{
		CtrlLayoutCancel(*this, "Window title");
		Sizeable(); FullScreen();
		button<<=THISBACK(DoPopup);
	}
	void DoPopup()
	{
		WithPopupLayout<TopWindow> dlg;
		CtrlLayoutCancel(dlg, "popup");
#ifdef PLATFORM_WIN32
		FrameLess().Maximize();
#ifndef _DEBUG
		dlg.TopMost();
#endif		
#else		
		Hide(); dlg.OpenMain(); dlg.Sizeable(); dlg.FullScreen();
#endif		
		dlg.ExecuteCancel();
#ifndef PLATFORM_WIN32		
		Show();
#endif		
	}
};



GUI_APP_MAIN
{
	MaximizeTest().Run();
}
