'Please wait...' type popups?

[bgowland]

Is it possible to have a popup without buttons that can be created then closed again after a certain task has completed?

Example - user clicks a button...popup appears saying 'Please wait...', some processing is done, popup is then closed by the plugin without user input.

Cheers,

I'm fairly sure there is a constructor for PopupMessageBox that takes no button names which can be used for this purpose. ie, assuming you're using the new BaseButtonUiTask or BaseButtonListUiTask then create it with something like:

setPopup(new Popups.PopupMessageBox(this, "please wait for download to complete"));

Then later dismiss it with:

setPopup(null);

Yes - using BaseButtonListUiTask for a PVRX2 plugin. I'll give it a try and see what happens.

Wouldn't you have to spawn a thread to do the actual work?

After the call to:

setPopup(new Popups.PopupMessageBox(this, "please wait for download to complete"));

You'd have to give control back, so that render processing would take place....

Or am I way off base???

No, its all done asynchronously. The rest of the code after setPopup() continues to execute.

He can then use the regular call to needsRendering() on the main thread to check the background work he is doing (either as chunks on the main thread or a continuous process on a background thread), then dismis the popup when it is complete.

Excellent. Thanks for the explanation.

Thanks JavaWiz for posing that question. The way I was going to do things doesn't quite tie-in with sub's explanation. Besides, I've got a bug in my background code anyway.

4am and it's time to take my programmer's head off (it hurts) and time to put my 'stare at the TV' head on.

I'll rethink things later.

I do it just as sub mentioned for my Netflix plugin. I call the function PopulateListWidget(), which launches the "Please wait.." popup and then calls a background worker thread with bgListWidget() to populate the list. At the end of bgListWidget(), I set the popup to null to clear the "Please Wait..." message.

Code:

protected override void PopulateListWidget()
        {
            setPopup(new GBPVRX2.Popups.PopupMessageBox(this, "\n\n\n\nRetrieving titles.\n\nPlease wait."));
            new Thread(bgListWidget).Start();
            
        }

        private void bgListWidget()
        {
            string ClientID = myFeeds.ClientId;
            ArrayList itemList = new ArrayList();
            string uri = string.Concat(baseUri, myMenu, "RSS");
            switch (myMenu)
            {
                // Snipped case statements.
            }
            if (myMenu != RssFeeds.Top100 && myMenu != RssFeeds.NewReleases)
                itemList = GetList(uri);

            uiList.setViewMode(UiList.ViewMode.MODE_DETAILS);
            setPopup(null);
        }

Thanks whurlston - nice example. Something similar should work OK for what I want to do.
