Left-clicking will deposit the component wherever the mouse is. Simply click on the theĭesired component in the gallery and then mouse will start to carry thatĬomponent to wherever you want it - no need to hold the mouse key down. That can be dragged onto the graphical design. Gallery of available components, such as panels, buttons, text fields, etc. Any change in one view will automatically be Views of GUI - Clicking these tabs will switch back andįorth between the graphical design view of the GUI vs. Highly recommeneded that only GUI initialization code be written in this WindowBuilder will subsequently and automatically generate the Java code toĬreate the desired GUI in initGUI(). Has been moved to a dedicated initGUI() method, Manager, of the component can be manipulated. The placement and size, within the constraints of the container's layout You can drag and drop components from the top bar onto this design canvas. Interface that shows you exactly how your GUI will look as you create it. This is a "what-you-see-is-what-you-get" ("WYSIWYG" or "wizzy wig") Simply drop a component into the frame or panel and WindowBuilder will fix the Initialization code into the initGUI() method or Initialization code, including the code it initially generated, into the Onto the frame or panel, WindowBuilder will then correctly move all the However, this bug is essentially benign because as soonĪs a component is dragged and dropped from WindowBuilder's component palette The code into the frame or panel's constructor. Should look like the following when you are finished:Įven after making the above preference settings, when aįrame or panel is first created, WindowBuilder does not put the GUI initialization code into a separate The WindowBuilder Swing Code Generation preference dialog Window/Preferences and then expand the WindowBuilder link toĬheck the box at the top of the "Init. While the default preferences in WindowBuilder are perfectly usable, forĬomp310, life is a lot easier and more convenient is the WindowBuilder Setting the Preferences for WindowBuilder ( Do this WindowBuilder always wants the implementation to be written using anonymous inner classes, not lambda functions.īottom line: Always let WindowBuilder write the initial ActionListener implementation by double-clicking the button in the designer view. ("Reparsing" will restore the designer view.) Doing so will result in WindowBuilder crashing when you double-click the button to try to go to the ActionListener code. KNOWN BUG (as of 9/18): WindowBuilder Designer does not understand lambda function syntaxĭo not use lambda function syntax to write things like ActionListener implementations for buttons. The project: on the main Eclipse menu, select If presented with the option, try clicking the " Reparse"īutton. Saved, then close the editor tab for that class.Īppears on the list, click on it, otherwise, click on " Other." Make sure that the class has no compile errors and is To force Eclipse to open the class with WindowBuilder, do the following: Sometimes Eclipse forgets that it should open a GUI class using WindowBuilder. Generated so change those preferences right away.įorcibly Opening a Class with WindowBuilder Preferences as detailed below, will reduce some of the incompatible code Please pay close attention to notes below concerningĬhanges that should be made to WindowBuilder's auto-generated code to insureĭesign compatibility with Comp310-taught principles. In such, it is important that certain auto-generatedĬodes be modified after they are created, before proceeding onward with anyįurther programming. They will present unnecessary difficulties when scaling the programs up into While the auto-generated code will certainly run, WindowBuilder's automatic code generator sometimesĬreates code that is incompatible with the architectural design principles If you are using an earlier version of Eclipse, e.g. "Indigo" installation, so no additional installation is necessary. WindowBuilder comes automatically with the default Eclipse
