# Change User Description Committed
#7 4225 Jeff Argast Added resolve support, reveal in finder, drag and drop edit,
show local files, and showing added files.
#6 3136 Jeff Argast Commented out extraneous NSLog
#5 3132 Jeff Argast Finally fixed the stupid wrapping problem.
Turns out there
are tabs in the text returned from Perforce.  No problem.
But in NSTextView if a tab occurs beyond the last tab stop
then NSTextView breaks the line.  So no what I want. The fix
is to create a bunch of tab stops out to the etherlands.
#4 3111 Jeff Argast Made multiple selection smarter by operating on the entire selection as an atomic
operation with the server. Also partially fixed the read only window to not wrap
at the window boundary.  I did the same for the editable window, but now the problem
appears to be that p4 change -o is breaking its output at some character location
before the string gets into the editor (at least I think that is the problem).
#3 2804 Jeff Argast The text still wraps so moved the task back to TODO.
Not sure
why it still wraps.
#2 2733 Jeff Argast Changed edit window to have horizontal scroll bar
#1 2732 Jeff Argast Initial submission of P4Cocoa
