Hello list, while Ian says that a "ListBox doesn't have code to scroll on mouse wheel events", I noticed that it works accidentally, but only with my self-written main loop, not with the new urwid.MainLoop() from the development version. Due to a lack of time, I did not reduce my working examples to the absolutely necessary to reproduce the issue (feature!), but the examples are short anyway :-)
1) It scrolls! ============== The following piece of code starts a self-written urwid main loop in the main thread, while another thread writes 100 lines of stuff into a file. Within urwid's main loop this file is polled and the content is displayed as new urwid.Text()'s in the ListBox. The overall amout of items in the ListBox is limited to 50: http://paste.pocoo.org/show/nrbHdItPOpyzAApYfLpQ/ Okay, after you've started the script, you will soon have reached the final state: a ListBox, populated with 50 items. When I then use my mousewheel, it scrolls the ListBox; it works like a charm. Is this true on your machines, too? I've tested it on Ubuntu 9.04 with "terminal" and "konsole", with "raw_diplay" and "curses_display" and with urwid 0.9.8.4 and the latest hg tip: it just works :-) 2) It doesn't :( ================ I've another example code that populates the ListBox, but this time with an os.pipe() (that's not interesting for now). The main difference is, that I used urwid.MainLoop() here: http://paste.pocoo.org/show/ZoEpBjDJ8ZZDwp0DMCMX/ Run it, see your ListBox getting populated with items and use your mouse wheel after the final state is reached: does it do anything? Not for me. The feature is gone :-) I'm interested in the reasons for this phenomenon! And I think that official and always-working mousewheel support would be great in general!
