The Settings menu

Set background color

The background color of the main layout window is the Java default for a Swing JPanel. If you're not happy with this then this function will change the color and GridBagger will remember the color between sessions. For backward compatibility with earlier Gridbagger versions the background color is not saved when saving a layout.

Use chained undo

The default way in which the undo function works is to bring back the last constraints change to a component and if undo is selected again the constraints will toggle back so the undo itself is undone.

By switching on undo chaining, the GridBagConstraints for a component can be progressively altered and each change is remembered by GridBagger. The undo function can then be used to step beck through the chain of changes.

The undo function is described more fully on the edit menu page.

Use color in components

When a component is added to a layout it is given a random color which will always be slightly different to any other color in the layout.

After adding about 90 components to a layout the color generating algorithm starts to have problems finding colors that are reasonably different from existing colors and the addition of components may become unacceptably slow. The way around this is to turn off the use of color. Of course you might want to do this anyway if the colors are annoying.

At end of source line

Different platforms and different editors expect different line terminators in ASCII files. This option allows the user to set the terminator that will be used when copying source to the clipboard or saving to a file.

Component highlight

By default the component highlight colors are animated. This option turns off animation for those users who don't like it.

Look and feel

Java supports different "look and feels" for the user interface. GridBagger offers the choice of using the cross-platform L&F (AKA "Metal") or using the system specific look and feel eg. Windows, Mac, Motif. The author suggests playing with this option to find which L&F suits you.
