Use of joptionpane

Recently I encountered a message prompt box in a swing program. The joptionpane class encapsulates many methods.

It was very convenient, So I simply sorted it out.

1.1 showmessagedialog

A modal dialog box with the OK button is displayed.

The following are several examples of using showmessagedialog:

Java code  

1. Joptionpane. showmessagedialog (null, "tip ");

The effect is as follows:

Java code  

1. Joptionpane. showmessagedialog (jpanel, "message", "title", joptionpane. warning_message );

The effect is as follows:

Java code  

1. Joptionpane. showmessagedialog (null, "message.", "title", joptionpane. error_message );

 

Java code  

1. Joptionpane. showmessagedialog (null, "message.", "title", joptionpane. plain_message );

 

 

1.2 showoptiondialog

This function can change the text displayed on the button. You can also perform more personalized operations.

General message box:

Java code  

1. Int n = joptionpane. showconfirmdialog (null, "are you happy? "," Title ", joptionpane. yes_no_option); // I = 0/1

The effect is as follows:

Personalized message box:

Java code  

1. Object [] Options = {"OK! "," Go to the other side! "};
2. Int M = joptionpane. showoptiondialog (null, "can I ask you? "," Title ", joptionpane. yes_no_option, joptionpane. question_message, null, options, options [0]);

The effect is as follows:

 1.3Showinoutdialog

This method returns an object type. This object type is generally a string type, reflecting the user input.

Example of a drop-down list:

Java code  

1. Object [] obj2 = {"football", "basketball", "Table Tennis "};
2. String S = (string) joptionpane. showinputdialog (null, "Please select your hobbies: \ n", "hobbies", joptionpane. plain_message, new imageicon ("icon.png"), obj2, "soccer ");

The effect is as follows:

 Example of text box format:

Java code  

1. Joptionpane. showinputdialog (null, "Enter your hobbies: \ n", "title", joptionpane. plain_message, icon, null, "Enter here ");

The effect is as follows:
