How do I synchronize GUI-Elements?
- by anonymous2500
Hello,
I have a little problem with my java-program. I wanna use Observer, to synchronize two GUIs.
But I can't synchronize the JComponent / JButton elements. For example:
I have a GUI-Class which implements the Observer-Class:
public class GUI extends JFrame implements Observer
I have a second "GUI"-Class which extends the JButton-Class and makes changes on a specific Button-Element.
public class Karte extends JButton{
...
this.setEnabled(false);
...
How do I synchronize this Button via Observable? I have already tried to use "extends Observable" in this class, but the "setEnabled()" method is explicit for the JButton-Class, which is not Observable!
Can someone help?
Thanks.
