Hi,

Just checking, if anyone knows what this error means: ValueError: Listbox type mismatch?

I get it when I try to set a 2-row-item list into Listbox item, which was initialized with 1-row-item list (or vice versa). I saw nothing in manual warning about this... Well, guess I have to create minimum 2 different Listbox items and carefully select which one to reuse

Wondering,

Well, I also faced this problem some days ago.

It seems it's about how you initialize the list. You need to initialize it in the same way you will use.

Example:

lb = appuifw.Listbox([u""], callback)

If you initialize it like this, it understands you'll have a 1 row listbox. So, if you try to set it into 2 row after initializing like that, you'll get that ValueError.

The solution is initializing it as a 2 row listbox already:

lb = appuifw.Listbox([(u"", u"")], callback)

This will prepare the listbox to receive an item and its description. Now you can set the list normally:

my_list = [(item, decription)]

lb.set_list(my_list)

Hope it helps,

Rafael.

Thanx for confirmation, I was suspecting that Since my current app-under-progress has nothing but listboxes (so far), then I'll have to create both types in advance.

Thanx,
