Fred Fish 396bf873e9 * gdbtk.tcl (files_command): Reorder the binding tags for
the listbox widget to avoid referencing the listbox after
	the containing widget has been destroyed by the action of
	a previous binding.

# gdb_loc.
#
# It will move the cursor, and scroll the text widget if necessary.
# Also, it will switch to another text widget if necessary, and update
# the label widget too.
#
# LINESPEC is a list of the form:
#
# { DEBUG_FILE FUNCNAME FILENAME LINE }, where:
#
# DEBUG_FILE - is the abbreviated form of the file name. This is usually
# the file name string given to the cc command. This is
# primarily needed for breakpoint commands, and when an
# abbreviated for of the filename is desired.
# FUNCNAME - is the name of the function.
# FILENAME - is the fully qualified (absolute) file name. It is usually
# the same as $PWD/$DEBUG_FILE, where PWD is the working dir
# at the time the cc command was given. This is used to
# actually locate the file to be displayed.
# LINE - The line number to be displayed.
#
# Usually, this procedure will just move the cursor one line down to the
# next line to be executed. However, if the cursor moves out of range
# or into another file, it will scroll the text widget so that the line
# of interest is in the middle of the viewable portion of the widget.
