Re: Very long listboxes

Hello,

The simplest you can do is add letter navigation. Note that depending on 
the exact control used, it isn't always natively available.

For exemple under windows, for wxListBox, wxComboBox and wxChoice, by 
default it works only with the first letter. If you rapidely type C and 
then H, the
first element starting with H will be selected, rather than the first 
element starting with CH.

It will works fully if you use wxListCtrl or wxListView instead.

You can of course implement or reimplement letter navigation yourself, 
it isn't that hard. I can share some code if you want.

However, it will look more modern if you add an instantaneous filter 
above the list, in a separate wxTextCtrl or similar. It is done in many 
apps nowadays.


By instant filter, I mean that whenever you type something in the text 
field, the list is refreshed and only shows matching items.

If you do something like this, it's simpler for you if you rely on the 
user data value / item data to identify what the user selected, rather 
than the
actual item string or index.

Hopes it helps.
