I just created my own layout. As the title say it's very easy to use and you can do everything you want.

LineLayout only use 4 differents operation to layout your entire GUI.

• add(Component comp)
• addSpace(Component comp, int space)
• addFill(Component comp, double fill)
• addExpend(Component comp, double fill, int max)
