It used to be the case that -1 represented the state of having no
current item, but that doesn''t seem to be the case now in 1.6. If I
modify groupbox.rb like so:
combobox = FXComboBox.new(group3, 5, nil, 0,
COMBOBOX_INSERT_LAST|FRAME_SUNKEN|FRAME_THICK|LAYOUT_SIDE_TOP)
combobox.appendItem("Very Wide Item")
for i in 0...3
combobox.appendItem("%04d" % i)
end
combobox.currentItem = -1
Then I get an IndexError. It also fails with setCurrentItem(-1). And it
fails using nil in place of -1.
The rdoc for FXComboBox says:
currentItem [RW] Index of current item, or -1 if no current item
[Integer]
Is there any way to say "no current item"?

No to be honest, the FXComboBox uses the FXList in browse-select mode, which means as long as there is at least ONE item, the current item should be >=0... - Jeroen -- +----------------------------------------------------------------------------+ | Copyright (C) 23:30 03/30/2006 Jeroen van der Zijp.

Maybe I was right all along and just didn''t know it. ;) Anyways. After the bug fix, FXRuby will at least be consistent with FOX in terms of setting the current item index to -1.
