[java] gui help

Well, you could use a JTable or maybe you want a JFileChooser.... there might be a component that do exactly what you want don''t know the name of it though....

JTable would do the trick.

Thx, that''s exactly what I wanted. Is there a way to prevent the user from editing the fields? I checked the documentation, but couldn''t find anything that suggested that.

You have to create a TreeModel that takes care of that... I think the method you want to override is

public boolean isEditable(int col,int row){
return false;
}

something like that should do it....

Ok I got another question.

I have several panels(info). Each panel has a JLabel followed by a JTextField. All these panels are then added to another panel (bottom)using a GridLayout. I put all the labels and textfields into seperate panels to keep the textfield size. How do I align these info panels inside the bottom panel so that they are left-aligned instead of all of them being centered?

Here''s the source if that''ll help you get an idea what I''m talking about.
