Question

libGDX Applications must implement the .resize(int width, int height) method, so I figured that resizing a libGDX app is not a big deal, but I found no way to make the actual application JFrame or whatever that is draggable as with JFrame.setResizable(true). Is that simply not possible with libGDX ?

If you use gdx-backend-lwjgl for you desktop app, then you can use:

LwjglApplicationConfiguration config = new LwjglApplicationConfiguration();
config.resizable = true;
new LwjglApplication(new YourGame(), config);

Use newest source from SVN trunk.
