import org.eclipse.swt.graphics.Color;
import org.eclipse.swt.widgets.Display;
import org.eclipse.ui.PlatformUI;
import org.eclipse.ui.themes.ColorUtil;

public class BackgroundColorPlugin implements IPropertyChangeListener {

    private static final String BACKGROUND_COLOR = "Background color";

    public BackgroundColorPlugin() {
        Display.getDefault().asyncExec(new Runnable() {
            @Override
            public void run() {
                Color backgroundColor = ColorUtil.getColor(StringConverter.asRGB(getBackgroundColorPreference()));
                PlatformUI.getWorkbench().getActiveWorkbenchWindow().getShell().setBackground(backgroundColor);
            }
        });
    }

    public static String getBackgroundColorPreference() {
        return PlatformUI.getPreferenceStore().getString(BACKGROUND_COLOR);
    }

    public static void setBackgroundColorPreference(String color) {
        PlatformUI.getPreferenceStore().setValue(BACKGROUND_COLOR, color);
    }

    @Override
    public void propertyChange(PropertyChangeEvent event) {
        if (event.getProperty().equals(BACKGROUND_COLOR)) {
            Display.getDefault().syncExec(new Runnable() {
                @Override
                public void run() {
                    Color backgroundColor = ColorUtil.getColor(StringConverter.asRGB(getBackgroundColorPreference()));
                    PlatformUI.getWorkbench().getActiveWorkbenchWindow().getShell().setBackground(backgroundColor);
                }
            });
        }
