The eclipse jface dialog box displays Chinese characters (a prompt box is displayed)

In jface, the dialog box is encapsulated through the shell window in SWT, and the button control object in SWT is called to viewSource codeIt can be found that the text of the set button is set by a character constant. The default value is English. To display a Chinese prompt, you must add a Chinese Language Pack.
In eclipse from entry to entry (version 2), it is described in eclipse 3.2.1. However, from the eclipse official website, it seems that the Language Pack only supports 3.2, and it will not be updated in the future. Fortunately, I don't need to define the entire eclipse. Now I need to display Chinese prompts IN THE jface dialog box.

I. Source Code
Take inputdialog as an example:

Inputdialog dialog = New Inputdialog (shell, "title", "enter a value", "1 ", Null );
If (Dialog. open () = inputdialog. OK ){
& Nbsp; string valuestr = dialog. getvalue ();
& Nbsp; messagedialog. openinformation (shell, "title", "input value:" + valuestr );
} Else // click the event button
Boolean call = messagedialog. openconfirm (display. getcurrent (). getactiveshell (), "OK", "Do you want to exit without warranty? ");
If (CALL) {// exit
System. Exit (0 );
}

Ii. default status
The default value is English:

3. Add a Chinese package
1. Download
Although the multi-language version is not available in eclipse 3.2, fortunately, for RCPProgramThis language pack is still useful.
To: Click
The Chinese package is in nlpack1. For rcpprogram, you only need to download nlpack1-eclipse-rcp-3.2-win32.zip.
After the download, extract the org. Eclipse. jface. nl1_3.2.0.v200606220026.jar file from the compressed package and put it in the project directory.

2. Set library reference for the project
Open eclipse, right-click the project name, select "properties", and click the "Libraries" tab under "Java build path:
Use "add jars..." to add the above libraries to the project directory. The result is as follows:
