Java-JFrame-swing nested browser steps

1. functions to be implemented using swing nested browsers:

By embedding a browser in a form using java swing, you can display the content of another project in this browser. You only need to go back to the url of the home page of another project, in this way, another project can be properly displayed in a nested swing browser;

 

Ii. When using the methods in the following browser tool class, you only need to obtain the stirng type url of the homepage of another project from the server of another project and the string type title to be displayed in the upper left corner of the browser. The parameters are url and title;

(1) main steps:

 

1. Use the following java code to create a browser;

2. Create a JFrame form and perform basic settings on the form;

 

3. Set the positioning size displayed by the browser and add the browser to the JFrame form:

Note: The java code that adds the browser to the form must be added to the java code of the toolbar at the top of the browser to the form. Otherwise, the browser content cannot be displayed.;

4. Set the icon on the left of the toolbar on the top of the browser;

5. Set the title text on the left of the toolbar on the top of the browser;

6. Set the pictures and mouse events on the right of the toolbar at the top of the browser, such as minimization, maximization, and closure;

7. Add an event to the form: when the size of the form changes, the Java code in the method body is executed, because the size of the form can be changed;

8. The following line of code must be commented out in the browser tool class. Otherwise, this form will not pop up when other forms call this form;

 

// The downstream code must be commented out; otherwise, the form cannot be redirected. // NativeInterface. runEventPump ();

 

(2) All the code for the tool class of the browser is as follows:
