B4J Question Why setting ChoiceBox items is slow?

[kimstudio]

I use following code to set items of ChoiceBox Cbx001 in AppStart, Cbx001 is on the form using designer. It is much slower than I expect as I though it should be no time, but I can see the form appears for around 2 seconds. Is this the right way to set items? Thanks.

    Dim lst As List
    lst.Initialize
    For i = 60 To 240
        lst.Add(i)
    Next
    Cbx001.Items.AddAll(lst)
    Cbx001.SelectedIndex = 2

Try it with Combobox (=B4XComboBox).

Thanks Erel. Combobox does show in almost no time! however I like the style of choicebox and found it is hard to style the combobox, the dropdown lists are very different between choice and combo.

ComboBox is more efficient as it doesn't create UI elements for each item.
