Eclipse插件从无到有–1.1菜单加个功能，弹出窗口

给about菜单加上一个功能，弹出about窗口

1.在about的action中加入class
class="zhch.illq.stools.actions.AboutAction"

<!-- action对应一个子菜单功能 ,class对应的是本菜单的处理类-->
<action label="About" icon="icons/stools.gif" tooltip="About stools"
	class="zhch.illq.stools.actions.AboutAction"
	menubarPath="stoolsMenu/aboutGroup" id="zhch.illq.stools.actions.AboutAction">
</action>

AboutAction内容

public class AboutAction implements IWorkbenchWindowActionDelegate{
	private IWorkbenchWindow window;
	public void dispose() {
	}
	public void init(IWorkbenchWindow window) {
		this.window = window;
	}

	public void run(IAction arg0) {
		MessageDialog.openInformation(
				window.getShell(),
				"About stools",
				"stools about. oh,shit!");
	}
	public void selectionChanged(IAction arg0, ISelection arg1) {
	}
}

保存，就行了
