Can't put content behind SWT Wizard Help Button

问题

I created a SWT based Wizard which has an own help Button by custom. Now i want to put some content behind that, so maybe a SWT browser will be openend and a predifined HTML Doc will be shown. But I don't have any clue where to access the Actions of the Help Button within my Wizard. Any idea?

I am assuming that you are using the standard JFace interfaces and classes for the wizard implementation. So, in your wizard page (extending org.eclipse.jface.wizard.WizardPage) you just have to override the performHelp method. See the below snippet.

@Override
public void performHelp() 
{
    Shell shell = new Shell(getShell());
    shell.setText("My Custom Help !!");
    shell.setLayout(new GridLayout());
    shell.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));

    Browser browser = new Browser(shell, SWT.NONE);
    browser.setUrl("http://stackoverflow.com/questions/7322489/cant-put-content-behind-swt-wizard-help-button");
    browser.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));

    shell.open();
}
