Full-screen while running

[Lethal Raptor Games 199]

Is it possible to change a window between full-screen and windowed mode while it is running? Can the full-screen window be created and then set as the default, then the old window deleted? ?

Nope, you create a new context on your new window.

I'm going to give myself the trophy but it means a lot more when the OP gives it to me.

Pretty sure you can.  I've changed resolutions before so I can't see a reason why you can't also specify windows/full-screen.  You may need to release the context first though.

Yeah I can change the resolution while it's running, but the only option I see for setting full-screen is in the Window::Create() function.  I was looking for window->SetFullscreenMode(bool) or something similar.  I'm wondering if releasing the window and recreating will cause problems... I should try it...

Yeah, that's what I meant.  What do you use to change the resolution?  SetLayout?  If so, how do you center the window (does it take the same argument Create does)?

[Lethal Raptor Games 199]

Ah okay.  I use SetLayout and center the screen using (GetSystemMetrics(SM_CXSCREEN) / 2) - (newWidth / 2).  SetLayout takes and x,y,width,and height arguments, but not a full screen argument.  It would be nice if it did.

[gamecreator 881]

Agreed.  Josh, I don't suppose you could make that a thing?  It's very relevant when changing resolutions in-game.

Create a new window and delete the old one.

Thanks.  Working now

int _index = comboboxFullscreen->GetSelectedIndex();
bool _oldFullscreenValue = Base::Config::fullScreen;
Base::Config::fullScreen = (_index == 0 ? true : false);

if (_oldFullscreenValue != Base::Config::fullScreen) {
	Context::GetCurrent()->Release();
	Window::GetCurrent()->Release();
	
	int _xPos = (Base::Config::fullScreen == true ? 0 : Base::desktopWidth / 2);
	int _yPos = (Base::Config::fullScreen == true ? 0 : Base::desktopHeight / 2);
	auto _newWindow = Window::Create(Base::GameTitle, _xPos, _yPos, Base::Config::screenWidth, Base::Config::screenHeight, (Base::Config::fullScreen == true ? Window::FullScreen : Window::Titlebar));
	auto _context = Context::Create(_newWindow);
}
else {
	Window::GetCurrent()->SetLayout((Base::desktopWidth / 2) - (Base::Config::screenWidth / 2),
		(Base::desktopHeight / 2) - (Base::Config::screenHeight / 2),
		Base::Config::screenWidth, Base::Config::screenHeight);
}
