[vdr] Updating menu items from separate thread

Hi!

I have a simple menu derived from cOsdMenu which displays selectable cOsdItem's.

Now I want to update the text of the cOsdItem's from a separate thread, which I do basically this way:

cOsdItem* item = Get(index); if (item) { item->SetText(text); Display(); }

But this doesn't seem to work very well. Sometimes only some of the cOsdItems are correctly shown with the new text, sometimes parts of the menu are completly invisible until I move the selection cursor over this area.

Any suggestions? Maybe this isn't possible at all?

Regards,

Tobias
