Solving Common Component Problems

This section discusses problems that you might encounter while using components. If you do not find your problem in this section, consult the following sections:

Problem: I am having trouble implementing a model (or some other code that is similar to something already in Java SE Platform, Standard Edition).

Problem: Whenever the text in my text field updates, the text field's size changes.

Problem: Certain areas of the content pane look weird when they are repainted.

Problem: My program is exhibiting weird symptoms that sometimes seem to be related to timing.

Problem: My modal dialog gets lost behind other windows.

Problem: The scroll bar policies do not seem to be working as advertised.

Problem: My scroll pane has no scroll bars.

Problem: The divider in my split pane does not move!

Problem: The setDividerLocation method of JSplitPane does not work.

Problem: The borders on nested split panes look too wide.

Problem: The buttons in my tool bar are too big.

Problem: The components in my layered pane are not layered correctly. In fact, the layers seem to be inversed — the lower the depth the higher the component.

Problem: The method call colorChooser.setPreviewPanel(null) does not remove the color chooser's preview panel as expected.
