The shared message area can be used by all parts of the application to write messages to this area.

Whole RCP application has access to the information in the shared status line therefore the information in the shared status line might be overwritten.

The following write a text to the status line.

				


package de.vogella.rcp.intro.statusline;

import org.eclipse.jface.action.IStatusLineManager;
import org.eclipse.swt.graphics.Point;
import org.eclipse.ui.application.ActionBarAdvisor;
import org.eclipse.ui.application.IActionBarConfigurer;
import org.eclipse.ui.application.IWorkbenchWindowConfigurer;
import org.eclipse.ui.application.WorkbenchWindowAdvisor;

public class ApplicationWorkbenchWindowAdvisor extends WorkbenchWindowAdvisor {

    public ApplicationWorkbenchWindowAdvisor(IWorkbenchWindowConfigurer configurer) {
        super(configurer);
    }

    public ActionBarAdvisor createActionBarAdvisor(IActionBarConfigurer configurer) {
        return new ApplicationActionBarAdvisor(configurer);
    }
    
    @Override
    public void preWindowOpen() {
        IWorkbenchWindowConfigurer configurer = getWindowConfigurer();
        configurer.setInitialSize(new Point(400, 300));
        configurer.setShowCoolBar(false);
        configurer.setShowStatusLine(false);
        configurer.setTitle("Status Line Example");
        configurer.setShowStatusLine(true);
    }
    
 // This is the new method
	@Override
	public void postWindowOpen() {
		IStatusLineManager statusline = getWindowConfigurer()
				.getActionBarConfigurer().getStatusLineManager();
		statusline.setMessage(null, "Status line is ready");
	}
}

Run your application. You should now see the following.

Add a view with the implementation class "de.vogella.rcp.intro.statusline.ViewPart1" to your application and your perspective. This view contains a button to set the status line.

				


package de.vogella.rcp.intro.statusline;

import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.ui.IActionBars;
import org.eclipse.ui.part.ViewPart;

public class ViewPart1 extends ViewPart {

	boolean pressed = false;

	@Override
	public void createPartControl(Composite parent) {
		Button setStatusLine = new Button(parent, SWT.PUSH);
		setStatusLine.setText("Set Statusline ");

		setStatusLine.addSelectionListener(new SelectionAdapter() {
			public void widgetSelected(SelectionEvent e) {

				String message = "I would like to say hello to you.";
				if (pressed) {
					message = "Thank you for using me";
				}
				setStatusLine(message);
				pressed = !pressed;
			}
		});
	}

	private void setStatusLine(String message) {
		// Get the status line and set the text
		IActionBars bars = getViewSite().getActionBars();
		bars.getStatusLineManager().setMessage(message);
	}

	@Override
	public void setFocus() {
	}

}

If you run it the result should look like the following.

From an editor you can access the status line via the following:

					


IEditorPart.getEditorSite().getActionBars();
