Instead, this book settles for a single chapter that covers the high points, but hits enough to prepare you to use JFace’s text editing capabilities in your applications. To explore it fully would mean describing how to build an award-winning programmer’s editor, which stretches far beyond the scope of this book. text, and all of which teem with both classes and interfaces, the text-editing framework in JFace would require tomes for complete coverage. Sprawling across eight distinct packages, all of whose names begin with org. Instead, JFace wraps StyledText with such an extensive MVC implementation that all the other widgets chafe with resentment. Such a VIP could never be left to languish with only the raw widget interface that StyledText provides. As the raison d’être of Eclipse, it enjoys the preferential treatment usually reserved for star athletes, rock stars, or supermodels. Layouts handled the relative positioning and sizing of controls as programmers learned how to harness their power, enthusiasm for layouts quickly grew.Īs chapter 11 explains, the StyledText widget receives a disproportionate amount of attention from SWT’s developers, because it forms the core of Eclipse. Developers no longer knew enough about all the target machines: what fonts were available, how large a text box would be to fit text vertically, how many pixels the decoration of a button would occupy, and so forth. However, the cross-platform nature of Java demanded the abstraction Java applications could be running on a variety of operating systems, on a variety of hardware. Aside from screen resolution technicalities, developers knew all they needed to know about the target machines when building applications, so absolute positioning made absolute sense. More puzzling, however, was the “layout” abstraction itself many programmers (read: Windows programmers) were accustomed to specifying exact locations and sizes for each control. After a time, Java IDEs began to incorporate custom layout managers that allowed developers to drag and drop controls, but early adopters had to do without GUI builders. Most programmers had learned to lay out controls by using drag-and-drop GUI builders or by editing resource files with AWT, they had to write code. AWT introduced layouts to an unsuspecting, and soon befuddled, programming audience.
