ways to add invisible components into JPanel?

I need to add some invisible component into a JPanel to avoid the issues with grid bag lay out.Which is开发者_Go百科 the best way to add these kind of invisible components?

You can use the helper methods of the Box class to create such components:

• Box.createHorizontalStrut(int width): Creates an invisible, fixed-width component.
• Box.createVerticalStrut(int height): Creates an invisible, fixed-height component.

Adding them is done in exactly the same way as you add any other component.

My first question would be "why are you using a GridBayLayout?", have you looked at the alternatives, like GroupLayout?

---

Erhmmm you just add them?

Like in:

  jpanel.add( youInvisibleComponent );

???

If you are having problems with the GridBagLayout, you should probably consider using another layout manager :(
