RCP: How to save and how to get TaskList TaskList

 

 

Eclipse RCP program if we add TaskList View, or used to manage the Task TODO items , the following code :

 

PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage() 
	.showView("org.eclipse.ui.views.TaskList");

 

 

We found that created Task, can not be saved after the restart , but in the Eclipse IDE does not have this problem . org.eclipse.ui.internal.views.markers.TasksView read the code , I found TasksView when the program exits , only responsible for keeping TasksView layout information . So , you need to add the Task how to save it ?

 

 

How to save TaskList

 the nature of the original Task

Marker, not stored in TasksView , but instead , and Resource associated with the object stored in the IResource . In the RCP program, you need to call IWorkspace Marker save the save method, you can call in preShutdown , the following code :

 

 

	@Override 
	public boolean preShutdown() { 
 
		/* Save workspace before closing the application */ 
		final MultiStatus status = new MultiStatus( 
				"com.voxana.vuidesigner.diagram", 0, "Saving Workspace....", 
				null); 
		IRunnableWithProgress runnable = new IRunnableWithProgress() { 
 
			@Override 
			public void run(final IProgressMonitor monitor) { 
				try { 
					IWorkspace ws = ResourcesPlugin.getWorkspace(); 
					status.merge(ws.save(true, monitor)); 
				} catch (CoreException e) { 
					status.merge(e.getStatus()); 
				} 
			} 
		}; 
		try { 
			new ProgressMonitorDialog(null).run(false, false, runnable); 
		} catch (InvocationTargetException e) { 
			e.printStackTrace(); 
		} catch (InterruptedException e) { 
			e.printStackTrace(); 
		} 
		if (!status.isOK()) { 
			ErrorDialog.openError(Display.getDefault().getActiveShell(), 
					"Error...", "Error while saving workspace", status); 
			return true; 
		} 
		return true; 
	}

 

 

Get TaskList

 

As stated earlier , Task (Marker of one type ) and Resource association is stored in the IResource . We can pass the following code to get all Task:

 

IResource root =  ResourcesPlugin.getWorkspace().getRoot(); 
String TypeId = "org.eclipse.core.resources.taskmarker"; 
IMarker[] markers = resource.findMarkers(TypeId, true, IResource.DEPTH_INFINITE);

 

 

where the first parameter specifies obtain Marker TypeId type ; second parameter specifies whether to search child nodes Marker; third parameter specifies the depth of the search .

 

in obtaining a IMarker , you can through the getAttribute method to get the parameters or getAttributes
