Chapter 16: LayoutManagers Chapter 16: LayoutManagers You may have noticed that despite the GUI widgets, the last few applets didn't look so hot. Strings were sometimes cut off. Buttons lay on top of labels, and other things weren't just the way you wanted them. LayoutManagers provide control over the locations of individual widgets in Java applets. Since you're never sure how big an area you'll have to work with or how it will be shaped, most of the controls are relative in nature. That is you say this widget should be above that one or left aligned with the other one; but you don't say that this widget's upper left hand corner is at pixel (42, 65). In this chapter you'll learn the five basic LayoutManagers included in the AWT and some additional tricks for handling complicated applets.
