Wrong size when switching to windowed mode

Administrator

Hi

I use the following code:
glWindow.setFullscreen(false);
glWindow.setUndecorated(false);
glWindow.setTopLevelSize(screenWidth,screenHeight);
glWindow.setTopLevelPosition(0,0);

Sometimes, the window size is 100 * 100 even though I call setTopLevelSize(1024, 780). Is it the right way of switching to windowed mode?

When I run my game, I see the window with a small size (100 * 100) during a fraction of second and then it goes fullscreen. The very first time I try to switch back to windowed mode, it sometimes goes back to this size instead of the passed size.

If every thing else was default and window size as desired
before switch to FS via "glWindow.setFullscreen(true)", then:

- is redundant
> glWindow.setTopLevelSize(screenWidth,screenHeight);
- that would be like fullscreen as a window
> glWindow.setTopLevelPosition(0,0);
- if you desire ..

I don't know what your goal is (size, props, ..) hence .. dunno.

Pls send little unit test case (copied from one of our ScreenMode tests maybe.

It's for my game. Some people prefer playing in windowed mode. I want the window to be always maximized but I think that if you create a window that you use immediately in full screen mode, it just uses a default value when switching to windowed mode.

Edit.: Does NEWT try to set a size when exiting full screen mode?

Hi

I solved my problem that way:
final GLWindow glWindow=joglNewtWindow.getNewtWindow();
final boolean fullscreenOn=glWindow.isFullscreen();
final int screenWidth=glWindow.getScreen().getWidth();
final int screenHeight=glWindow.getScreen().getHeight();
glWindow.setFullscreen(!fullscreenOn);
glWindow.setUndecorated(!fullscreenOn);
glWindow.setTopLevelSize(screenWidth,screenHeight);
glWindow.setTopLevelPosition(0,0);
glWindow.invoke(false, new GLRunnable() {

@Override
public boolean run(GLAutoDrawable glAutoDrawable) {
glWindow.setTopLevelSize(screenWidth,screenHeight);
return true;
}
});

I was right, the switch to windowed mode tries to reset the latest size of the window in this mode which is close to 100 * 100 when you just create a GLWindow that you immediately puts into full screen mode. I assume it is intentional and not a bug. Invoking setTopLevelSize a bit later seems to work.

So setting size on the next GL display is deferred, i.e.
after leaving fullscreen mode and reset back to default size
which is actually 128 x 128.

How about setting the default size before setVisible(true) ?
It won't affect your desired fullscreen mode,
but define the size when you leave fullscreen.

If that doesn't work, it's a bug
and we should copy one of the ScreenMode unit tests for this purpose.
The latter already test combination of this - maybe not your case exactly.

It's an excellent idea, I'm going to give it a try.

Edit.: It is really better now.
