如何在Eclipse RCP中将首选项页面的默认title从“首选项”更改为“设置”？

Answer 1

If you are using the org.eclipse.ui.preferencePages then I think it is not possible. The help of the same says:

The workbench provides one common dialog box for preferences. The purpose of this extension point is to allow plug-ins to add pages to the preference dialog box . When preference dialog box is opened (initiated from the menu bar), pages contributed in this way will be added to the dialog box.

But there is a way round. Follow the below steps ( This is just showing how you can change the title text ):

1. Create an action for opening the preference dialog
2. Make a new class extending the org.eclipse.jface.preference.PreferenceDialog
3. In the sub-class override the configureShell method
4. Invoke the PreferenceDialog from the above created action

Extended Class

class MyPreferenceDialog extends PreferenceDialog
{
    public MyPreferenceDialog(Shell parentShell, PreferenceManager manager) {
        super(parentShell, manager);
    }

    protected void configureShell(Shell newShell) {
        super.configureShell(newShell);
        newShell.setText("Settings"); 
    }
}

Code For Invocation

Button prefButton = new Button(top, SWT.PUSH);
prefButton.setText("Preference");
prefButton.addSelectionListener(new SelectionListener() {
    public void widgetSelected(SelectionEvent e) {
        final PreferenceManager preferenceManager = PlatformUI.getWorkbench().getPreferenceManager();
        MyPreferenceDialog dialog = new MyPreferenceDialog(top.getShell(), preferenceManager);
        dialog.create();
        dialog.open();
    }
    public void widgetDefaultSelected(SelectionEvent e) {
    }
});

The resultant preference dialog looks like this:
