JAVA WINDOWBUILDER TUTORIAL PDF

Concepts: Editors and Renderers Before you go on to the next few tasks, you need to understand how tables draw their cells. You might expect each cell in a table to be a component. However, for performance reasons, Swing tables are implemented differently. Instead, a single cell renderer is generally used to draw all of the cells that contain the same type of data.

Installation WindowBuilder comes automatically with the default Eclipse "Indigo" installation, so no additional installation is necessary. If you are using an earlier version of Eclipse, e. While the auto-generated code will certainly run, they will present unnecessary difficulties when scaling the programs up into larger systems.

In such, it is important that certain auto-generated codes be modified after they are created, before proceeding onward with any further programming. Setting the preferences as detailed below, will reduce some of the incompatible code generated so change those preferences right away. To force Eclipse to open the class with WindowBuilder, do the following: Make sure that the class has no compile errors and is saved, then close the editor tab for that class.

WindowBuilder Designer will not open If presented with the option, try clicking the "Reparse" button. It may take several attempts. Doing so will result in WindowBuilder crashing when you double-click the button to try to go to the ActionListener code. WindowBuilder always wants the implementation to be written using anonymous inner classes, not lambda functions.

Bottom line: Always let WindowBuilder write the initial ActionListener implementation by double-clicking the button in the designer view. Then fill in the actionPerformed method.

While the default preferences in WindowBuilder are perfectly usable, for Comp, life is a lot easier and more convenient is the WindowBuilder preferences are slightly adjusted. Under "Variable Generation", check the box at the top of the "Init. Field" tab. Even after making the above preference settings, when a frame or panel is first created, WindowBuilder does not put the GUI initialization code into a separate method, e.

Work-araound: Either manually move the initialization code into the initGUI method or simply drop a component into the frame or panel and WindowBuilder will fix the problem automatically. You can drag and drop components from the top bar onto this design canvas. It is highly recommeneded that only GUI initialization code be written in this method. Any change in one view will automatically be reflected in the other. Palette of GUI Components -- This is a gallery of available components, such as panels, buttons, text fields, etc.

Simply click on the the desired component in the gallery and then mouse will start to carry that component to wherever you want it -- no need to hold the mouse key down. Left-clicking will deposit the component wherever the mouse is. WindowBuilder will light up placement targets corresponding to the current layout of the target component to aid you in properly locating the new component.

Hint: Sometimes it is difficult to drop a component exactly where you want it on the graphical design view. Containers such as panels and frames are shown as parent nodes to the components that they contain. Filling out the values for the properties here will cause WindowBuilder to auto-generate the corresponding code. Likewise, code added to the initGUI method will show up here. Click Here to See Events Tied to the Selected Component -- Clicking on this icon will display the events to which the selected component listens.

Double-clicking an event will cause WindowBuilder to auto-generate an anonymous inner class listener for that event for that component.

Under "WindowBuilder", expand "Swing Designer". Select "JFrame". Click "Next". In the subsequent dialog window, be sure that the package name is correct and type in the desired class name for your new GUI frame.

Use a clearly descriptive name that tells the reader what this frame is for and that it is a frame, e. The "Use Advanced Template" checkbox should be checked. Click "Finish" Perform the following code clean-up steps to make the auto-generated code compatible with Comp design principles. These changes will make your code much easier to migrate into a true Model-View-Controller architecture later, as well as make it applet-compatible i.

Subsequent auto-generated code will be created in this new method. Move the setVisible true statement out of main and into a public start method of the frame. This encapsulates the GUI startup process away from the application startup process. In main :.
