Thread: Changing a JButton background

Hi

So I'm making a small game in NetBeans. In my GUI I have a jButton and I want to know, is it possible to change the background of the JButton once it has been set? If so, can I change it from a separate method in a different class? If not, what else can I do?

Thanks

Changing an object that belongs to another class is usually done with a "setter" or mutator method. In your case, the class that owns the JButton might have a method, public void setButtonBackground( Type background ), that can be called by other classes to change the button's background. If you're not familiar with 'getter' (accessor) and 'setter' (mutator) methods, then you should search for those topics and learn about them.

Yeah I know what accessors and mutators are, but I can't find one for the button to set the background.

Did you check the JButton API page?

If you mean to set a picture on jbutton, you can do that with
button.setIcon(new ImageIcon("full image path here(c:/my/images/bigboom.jpg), or path in working directory(boom.png), image types of jpg, png, gif...")), also there is similiar methods for disabled icon, selected icon, pressed icon, mouse over button icon ...

Yeah I figured that out thanks, my whole program is so messed up though i don't know why it builds and compiles perfectly but it just doesn't work
