Hi! While playing (again) to add Function keys support, reading documentation of how keyboard handling works on our vm and other platforms: .Net: http://msdn.microsoft.com/en-us/library/system.windows.forms.control.keydown... Javascript: http://www.quirksmode.org/js/keys.html And a quick explanation of Igor of how our vm works: http://lists.squeakfoundation.org/pipermail/vm-dev/2011-November/009661.html What puzzles me is some of the following: - Keypress event should only be raised to send keystrokes having a character representation. - but some keystrokes with no character representation are taken as keypresses! (arrowup, arrowdown, esc...) (and so, used to handle events instead of doing it on keydown) - the strokes above should be only raised in keydowns IMHO. - more on, we have in Character class representations for those *non characters* :P which is funny because they are not characters. And everything works, and fits in a kind of strange way :). Now, rearranging this to follow those conventions means: - reify Keys (vs Characters). So we can model modifier keys, function keys, arrow keys, independent from Characters. - Keys (non-characters) should only be raised as single events on keydown. - and the worse part is to fix all the hardcoded shortcuts messed everywhere in the image. Any thoughts on this? Thanks! Guille
