I don't see why you wouldn't use JInternalFrames for this, but you could use multiple JFrames. Just have them all launched from a common class that handles how they are layed out through setBounds() calls. You can also attach ComponentListeners to the JFrames if you want them to move in relation to each other... have the componentMoved() method call something in ...

If you initialize it to null, that's not going to prevent a *Null*PointerException... You're going to have to pass a reference to an actual object of the MyPaint class that the paintWindow reference can point to. You can do this through either a constructor parameter, or through some kind of set method (or, if the ColorWindowAdapter is an inner class, you ...

24. Frame problem "Java"?    coderanch.com

It's good practice to first construct the GUI, and then start doing something with it. You really shouldn't mix the two. The top-level code might look like this: JFrame bigTextArea = new JFrame("Queens College Rooms"); bigTextarea.setLayout(new GridLayout(1,2)); bigTextArea.setDefaultCloseOperation(JFr... bigTextArea.setSize(400,600); JTextArea jta1 = new JTextArea(); bigTextArea.getContentPane().add(jta1); displayResults(jta1, myRooms); // TODO: sort the rooms array here JTextArea jta2 = new JTextArea(); bigTextArea.getContentPane().add(jta2); displayResults(jta2, ...

I'll venture again though, this time to guess that there may be a static issue here (perhaps?). Does any of your code use static fields? Could you be reusing the same ...

35. problem with jframes    java-forums.org

I would use listeners here such as a ChangeListener or even pass an ActionListener from one class to the other. But before doing that, think whether you truly want two JFrames here. Most Swing apps have only one JFrame, the main frame, and then if other windows are needed they use dialogs such as a JDialog.

Your other thread has been deleted. Regarding your question, you have one ojbect access other objects in Swing same way as any other Java program: One object needs a reference to the other, often held in a variable in order to be able to call methods on the other object. So for instance, Java Code: class JFrame1 extends JFrame { public ...

If it's opening a whole new window, then my guess is that you're creating a new JFrame object each time, in some of the code that you haven't posted. Sharing only selected snippets of code is almost never helpful, because doing so means that you're making a judgement about where the problem lies -- and if you were right in that ...
