Add menu and toolbar to view

This article has three sections which are "Add Menu", "Add Drop-down List", "Add Toolbar".

Section 1: Add Menu

1. Add command extension point: org.eclipse.ui.commands. Add command to command extension and set the id: CustomPlugin.commands.Hello


2. Every command should have a handler which is responsible for making responses after calling the command from the menu. Add code to the default handler: customplugin.handlers.SayHello. When the user click the "Hello" menu, a "Say Hello" dialog will popup.

import org.eclipse.core.commands.AbstractHandler;
import org.eclipse.core.commands.ExecutionEvent;
import org.eclipse.core.commands.ExecutionException;
import org.eclipse.jface.dialogs.MessageDialog;

public class SayHello extends AbstractHandler {

	public Object execute(ExecutionEvent event) throws ExecutionException {
		// TODO Auto-generated method stub
		MessageDialog.openInformation(null, "Say Hello", "Hello");
		return null;

3. Add menu extension: org.eclipse.ui.menus. And add the menu contribution to the extension. The locationURI is important to control the position of the menu.

There are some examples of locationURI from the eclipse website:

  • -insert this contribution in the main menu after the Window menu.
  • menu:file?after=additions-insert this contribution in the File menu after the additions group. Equivalent to the old menubarPath="file/additions".
  • menu:org.eclipse.ui.views.ContentOutline?after=additions -insert this contribution in the Content Outline view dropdown menu after the additions group.
  • toolbar:org.eclipse.ui.views.ContentOutline?after=additions -insert this contribution in the Content Outline view toolbar, after the additions group.
  • popup:org.eclipse.ui.examples.propertysheet.outline?after=additions -insert this contribution in the Property Sheet outline page context menu after the additions group.

In the implementation of adding menu to a view, the locationURI should be "menu:" + view id. Here is menu:CustomPlugin.views.ExampleView1


4. Add command to the menu contribution, The command id is CustomPlugin.commands.hello


5. Result

Section 2: Add Drop-down List

In this section, a drop-down list menu will be added to the menu. And the secondary menu will also show a "Say Hello" dialog.

1. Based on the previous implementation, add "menu" to menu contribution and set the menu label to “Hello Menu 2nd”.
