#258 alt-F4 doesn't quit in windows
A couple of minor user interface glitches in the current
production DrJava on WinXP.
1) alt-F4 doesn't do anything. For consistency with
other windows apps, it should cause the application to
quit (as cntrl-q does now).
2) When the "do you really want to quit" dialog pops up,
typing y or n doesn't do anything. One has to type alt-
y or alt-n. It'd be nice if y and n worked by themselves.

I'm looking in to the alt-F4 problem. That is definitely a
bug, and has been present since the 2004-02-13 release. The
other issue has to do with how Java treats accelerator keys;
that is more properly a feature request, but I'll leave it
here for now.

I've found the source of the problem with alt-F4, and the
fix will be in CVS soon. It has to do with the addition of
granular undo -- to prevent problems with the undo logic,
all key events were processed using the default behavior of
a JEditorPane, then consumed. Apparently, a JEditorPane
would not consume the edit by default, allowing another
handler to consume it and close the window. In fact, it
seems that we often consume events that we don't need to
consume -- I removed several calls to consume the key event.
Alt-F4 once again quits.
Slightly longer-term, we should refactor the way we process
key events. There is a method in JEditorPane called
processComponentKeyEvent which is meant to be overridden for
custom key handling; we should use that method instead of
processKeyEvent itself.
Anyway, the fix is being committed to cvs as I type. I'm
closing this report; I opened up a separate feature request
for the accelerator keys, Feature Request #935412.
