How to display waiting circle? (1 Viewer)

[Vattenmelon]

Can anyone tell me how to show that waiting animation from a plugin? I have seen some code that uses "use Waitcursor" but can't really get it working.

Hi,

it should be enough to say

GUIWaitCursor.Init();
GUIWaitCursor.Show();
.
.
.do what ever
.
.
GUIWaitCursor.Hide();


Thats all, the class is static.

Hmm.. I still can't see the waitcursor, do I need to put anything in the skin-file?

EDIT:
Well, it seems that I can display it. The problem is that it is only displayed after the timeconsuming part is done. For instance I would like to display the waitcursor, and then download some data from the internet.

If I have
GUIWaitcursor.show();
downloadData() // takes 15 secs
GUIWaitcursor.hide();

the cursor isn't displayed at all.

Guess I have to fiddle with threading or something to do that.

Hmm,


I tried it here and put the Show() in Onload of one plugin. The cursor is there and stays.

Are you doing that Onload ? Maybe this best way would be using a backgroundworker.

Yes I tried to do it in the onload method. If I remove GUIWaitcursor.hide(); the cursor appears at the same time as the list is filled, and after the screen has been blank for some seconds. I'll have to try with a backgroundworker or something.

Something like this:

_workerCompleted = false;

BackgroundWorker worker = new BackgroundWorker();

worker.DoWork += new DoWorkEventHandler(_DownloadWorker);
worker.RunWorkerAsync(arg);

while (_workerCompleted == false)  GUIWindowManager.Process();

one of the last pieces of old code from a plugin I've taken over Seems like calling GUIWindowManager.Process() is another way to display a wait cursor...

Thx guys.. the solution for me was

        protected override void OnPageLoad()
        {
             GUIWaitCursor.Init();
             GUIWaitCursor.Show();
            _workerCompleted = false; //class member boolean

            BackgroundWorker worker = new BackgroundWorker();

            worker.DoWork += new DoWorkEventHandler(createList);
            worker.RunWorkerAsync(new object());

            while (_workerCompleted == false) GUIWindowManager.Process();
            GUIWaitCursor.Hide();
            
        }

        private void createList(object sender, DoWorkEventArgs e)
        {
            Artists artists = cAmpache.GetAllArtists();
            foreach (Artist item in artists.Items)
            {
                GUIListItem i = new GUIListItem(item.name);
                i.TVTag = item;
                this.facadeView.Add(i);
            }
            _workerCompleted = true;
        }

In a perfect world I would like the to not have the _workerCompleted = true in the createList method..but the most important for the moment was that it worked.

You're already using GUIWindowManager.Process(); do you still need the GUIWaitCursor show/hide methods?

 

[Vattenmelon]

Yes after what I can see I do.
