Eclipse RCP Experiments

When you use some of the Eclipse IDE plugins they may contribute preference pages that you may not necessarily want to show to your users.

Remove them in the ApplicationWorkbenchWindowAdvisor.postWindowCreate():

PreferenceManager pm = PlatformUI.getWorkbench( ).getPreferenceManager();
pm.remove("org.eclipse.ui.preferencePages.Workbench");

The "org.eclipse.ui.preferencePages.Workbench" id removes the "General" preference page group. If you do not know the id for the page you want to remove. You can first print them like this:

PreferenceManager pm = PlatformUI.getWorkbench( ).getPreferenceManager();
IPreferenceNode[] arr = pm.getRootSubNodes();
        
for(IPreferenceNode pn:arr){
    System.out.println("Label:" + pn.getLabelText() + " ID:" + pn.getId());
}

How to set color and font for a table cell using TableViewer in JFace?

All you need to do is make your ITableLabelProvider implementation also implement ITableFontProvider and ITableColorProvider.

public class TypeLabelProvider implements ITableLabelProvider, 
ITableFontProvider, ITableColorProvider {
     ...
     ...
     ITableLabelProvider methods
     ...
     ...

     @Override
     public Font getFont(Object element, int columnIndex) {
           return JFaceResources.getFontRegistry().getBold(
                                   JFaceResources.DIALOG_FONT);
     }

     @Override
     public Color getBackground(Object element, int columnIndex) {
           return new Color(display, new RGB(125,189,0));
     }

     @Override
     public Color getForeground(Object element, int columnIndex) {
         return new Color(display, new RGB(125,189,0));
     }
}
