[閒聊] How to write a hyperlink in Eclipse Plug-in

[TonyQ (沉默是金。)]

        I mean to write a link to allow user click and
        open system browser to view the page.

        (Like official help page , reference link ....etc)

        You could use Link widget ( org.eclipse.swt.widgets.Link )

        The routine is ,

        1. create a link widget
        2. set text with <a> tag(just like html)
        3. add selection listener , (the e.text will be the herf from tag)
        4. open browser.


        The following sample code below.

===========

Link link = new Link( parent, style );
link.setText("<a href=\"http://www.google.com.tw\">hello hyperlink</a>");
link.addSelectionListener(new SelectionListener(){
  public void widgetSelected(SelectionEvent e) {
    if(e.text!=null && !"".equals(e.text)){
      try {
        BrowserUtil.openSystemBrowser(null, e.text,false);
      } catch (Exception e1) {
        e1.printStackTrace();
      }
    }
  }
  public void widgetDefaultSelected(SelectionEvent e) {
    //do nothing
  }
});


=============

the browser util class

=============
public class BrowserUtil {
  public static IWebBrowser openSystemBrowser(String browserid, String
url,boolean embed) {
    try {
      IWorkbenchBrowserSupport browserSupport =
                PlatformUI.getWorkbench().getBrowserSupport();
      IWebBrowser browser = null;
      if(embed){
        browser = browserSupport.createBrowser(browserid); //$NON-NLS-1$
      }else{
        browser = browserSupport.getExternalBrowser();
      }
      browser.openURL(new URL(url));
      return browser;
    } catch (Exception e) {
      return null;
    }
  }
}
