Loading Large lists - uiSimpleList, UiList

[psycik]

Hi, got a pretty large list that's I want to load in uiList - so I can thumbnail it later on but changing viewmode.

Any tips and tricks for loading such a large list (in the 000's).

I've pushed it to a new thread, and then every ten items update the list:

Code:

listCounter++;
if (listCounter % 10 == 0)
    this.internalUIList.setItemList(itemList);

And while this works pretty well, you can't navigate that list as it keeps moving the selected index after each update.

And and while I'm asking about lists, how can I stop word wrapping...

Thirdly, sub, can you check (if you have time) the firing of ExitRight froma UiList. ExitLeft seems to be kicked off, but not the right.

you could try
idx = uiList.getSelectedItemIndex();
uiList.setItemList(itemList);
uiList.suggestSelectionIndex(idx);

that should keep the index where it is.

Thanks I did think of that but only this morning. Sometimes its good to have a break to "free the mind".

Now I've got to work out that ExitRight problem...

I just checked and it looks like it should be calling the ExitRight. This is with a UiSimpleList, not UiList? The latter doesnt call ExitRight.

On the wrapping thing, when you define your CompositeImages you can specify the wrap="false" attribute on any <DrawText> elements.

cool on the wrapping thing.

Ahh, I'm using two UiSimpleLIsts (Artists listing and Album listing) but using a UiList for the title listing so I can switch to icon view. And so this doesn't trigger a exit right...hmm any reason why it doesn't??

Hopefully I can get around that without breaking too much.

It just wasnt something I needed when I originally created the UiList, since these were only really intended for use on simple screens with buttons on the left and list on the right. I did have the ExitRight() for the UiSimpleList, since I used three of these on the Search Guide screen and needed to be able to switch between these lists.

Can it be added for next release possibly?? I just know to get around it I'm going to need a bunch of if (key == right and screen = title) type statements where for everything else I've managed to be really generic and use keymappings.

If you remind me when the release gets a bit closer then I'll try to add it.

I cant modify the existing UiList.CommandCallback interface to add this method, since that'd break every existing plugin, but I can look into adding an optional UiList.CommandCallback2 interface which adds the ExitRight().
