![]() ![]() Layouts − They define how UI elements should be organized on the screen and provide a final look and feel to the GUI (Graphical User Interface). GWT provides a huge list of widely used and common elements varying from basic to complex, which we will cover in this tutorial. UI Elements − These are the core visual elements the user eventually sees and interacts with. Įvery user interface considers the following three main aspects − Įclipse − Eclipse is also a Java IDE developed by the Eclipse open source community and can be downloaded from. Netbeans − Netbeans is a Java IDE that is open source and free, which can be downloaded from. Notepad − On Windows machine, you can use any simple text editor like Notepad (Recommended for this tutorial), TextPad. ![]() But for now, you can consider one of the following − There are even more sophisticated IDE available in the market. To write your Java programs, you will need a text editor. Refer to your Shell documentation if you have trouble doing this.Įxample, if you use bash as your shell, then you would add the following line to the end '.bashrc: export PATH=/path/to/java:$PATH'. Setting Up the Path for Linux, UNIX, Solaris, FreeBSDĮnvironment variable PATH should be set to point to where the Java binaries have been installed. Step 1 − Edit the 'C:\autoexec.bat' file and add the following line at the end: 'SET PATH=%PATH% C:\Program Files\java\jdk\bin'. Example, if the path is currently set to 'C:\WINDOWS\SYSTEM32', then change your path to read 'C:\WINDOWS\SYSTEM32 c:\Program Files\java\jdk\bin'. Step 3 − Alter the 'Path' variable so that it also contains the path to the Java executable. Step 2 − Click the 'Environment variables' button under the 'Advanced' tab. Step 1 − Right-click on 'My Computer' and select 'Properties'. Setting Up the Path for Windows 2000/XPĪssuming you have installed Java in c:\Program Files\java\jdk directory − ![]() Once you have installed Java on your machine, you would need to set the environment variables to point to the correct installation directories. Hence, you can download a version based on your operating system.įollow the instructions to download Java and run the. Java SE is freely available from the link Download Java. Please use the following steps to set up the environment. This section guides you on how to download and set up Java on your machine. Pluggable look-and-feel − SWING based GUI Application look and feel can be changed at run-time, based on available values. Highly Customizable − Swing controls can be customized in a very easy way as visual apperance is independent of internal representation. Rich Controls − Swing provides a rich set of advanced controls like Tree, TabbedPane, slider, colorpicker, and table controls. Light Weight − Swing components are independent of native Operating System's API as Swing API controls are rendered mostly using pure JAVA code instead of underlying operating system calls. Because of which, Swing has a pluggable look-and-feel architecture. ![]() Swing component has Model as a seperate element, while the View and Controller part are clubbed in the User Interface elements. View represents visual representation of the component's data.Ĭontroller takes the input from the user on the view and reflects the changes in Component's data. Swing API architecture follows loosely based MVC architecture in the following manner. Swing component follows a Model-View-Controller architecture to fulfill the following criterias.Ī single API is to be sufficient to support multiple look and feel.ĪPI is to be model driven so that the highest level API is not required to have data.ĪPI is to use the Java Bean model so that Builder Tools and IDE can provide better services to the developers for use. It is build on top of AWT API and acts as a replacement of AWT API, since it has almost every control corresponding to AWT controls. Swing API is a set of extensible GUI Components to ease the developer's life to create JAVA based Front End/GUI Applications. ![]()
