Question

A while ago, I read that the best way to switch between different “screens” in an application would be to set up different JFrames and then simply dipose the first and call the second. For example I have Screen A extending JFrame and Screen B extending JFrame, on a button that should switch to the next screen I would write something like that

JButton button = new JButton("show next screen");
button.addActionListener(){
    new ScreenB();
    frameA.dispose(); // assumed that we coded something like frameA = this earlier
}

Now the problem is that between the changeover of the two frames, I see for let’s say 1/10 either Screen A or Screen B, which is very ugly. What would be a better solution? Extending the screens as Container and set them as ContentPane for the always the same JFrame?

Answer 1

Try attaching a WindowListener to FrameA

In you action listener call frameA.dipsose(), so long as the frame set set to DISPOSE_ON_CLOSE it will trigger a windowClosed event in the WindowListener.

When this occurs, you can now open you new window.
