JFrame can make a form similar to the QQ login function. Through JFrame, Java code can be used to realize the form function, which is generally used for the development of C (client) of CS projects;

1. What is JFrame?

Using JFrame, you can write java code by yourself, or install the windowbuilder plug-in in eclipse, so that you can use the windowbuilder plug-in to quickly create and operate the form visually, and quickly realize the development of programming;

The general steps for visual development of JFrame form through eclipse using windowbuilder plug-in are as follows:

2. Use steps

1. Add the windowbuilder plug-in to eclipse:

1. First check your eclipse version:

 

 

2. Select the http address of the corresponding version number on the windowbuilder plug-in website through the eclipse version: URL: WindowBuilder | Download | The Eclipse Foundation

 

 

3. Then install the windowbuilder plug-in in eclipse:

　　eclipse-->help-->Install New SoftwareOpen:

Name: Just write a name, it is best to know the name, such as: windowbuilder

Locatioin: It is to write the address in the http column just obtained according to the eclipse version;

In the next step, select all, then the next step until complete, then restart eclipse to complete;

2. Create a windowbuilder java project in eclipse, and create a java entity class for visual development:

1. Create a java project through windowbuilder:

 

2. Add jar packages: DJNativeSwing-1.0.0.jar, DJNativeSwing-SWT-1.0.0.jar, org.eclipse.swt.win32.win32.x86_64-4.3.jar (this jar package depends on whether the computer is 32-bit or 64-bit bit to download, in this case a 64-bit operating system)

3. Create a java entity class through windowbuilder: new--->other:
