I have a JFrame-descendant window a with a JMenuBar and two components stored in a JPanel. One is a JTabbedPane, which occupies the majority of the screen, and the other is small JPanel that in turn contains a series of buttons. They are constructed as such:
//in constructor:
menubar = new BFIDEMenuBar(this);
setJMenuBar(menubar);
content = new JPanel();
add(content);
buttons = new BFIDEButtonBar();
editors = new JTabbedPane();
content.add(buttons, BorderLayout.NORTH);
content.add(editors, BorderLayout.CENTER);
When the window is smaller than a certain size, the components arranged as expected: the JTabbedPane occupying the center with the "buttons" JPanel centered above it:
However, if the window is re-sized beyond a certain threshold, the JPanel changes location:
Shrinking the window causes it to jump back to its previous (correct) position.
I have read the javadoc for BorderLayout and I have used it before, but I have yet to encounter this phenomenon. The javadoc says that "The NORTH and SOUTH components may be stretched horizontally;" but I don;t this counts as stretching.
No other methods are called from the constructor save for adding a few listeners and the obligatory setVisible, setEnabled, and the like.
Any thoughts on why this is happening or how to rectify it?
