LWJGLException when switching from full-screen to windowed context #798
Description
If I start a JME application in windowed mode, I can switch to full-screen mode at any time, provided my settings match one of those supported by my graphic adapter.
However, if I start in full-screen mode, any attempt to switch to windowed mode crashes the application.
I see this issue with both JME 3.1.0-stable and JME 3.2.0-stable
Here is my test app:
package mygame;
import com.jme3.app.SimpleApplication;
import com.jme3.input.KeyInput;
import com.jme3.input.controls.ActionListener;
import com.jme3.input.controls.KeyTrigger;
public class Main extends SimpleApplication {
public static void main(String[] args) {
Main app = new Main();
app.start();
}
@Override
public void simpleInitApp() {
inputManager.addMapping("goWindowed", new KeyTrigger(KeyInput.KEY_P));
ActionListener listener = new ActionListener() {
@Override
public void onAction(String name, boolean keyPressed, float tpf) {
if (name.equals("goWindowed") && keyPressed) {
goWindowed();
}
}
};
inputManager.addListener(listener, "goWindowed");
}
void goWindowed() {
settings.setFullscreen(false);
setSettings(settings);
restart();
}
}
Here is typical output:
