#
# This snippet redefines the MakeScroller function in the qhandles
#  module, eliminating the need for a new qhandles.py file.
#



#
# This attaches the item to the options menu; it's best for new
#  facilities to redefine menus etc in the quarkpy modules rather
#  than modify the files themselves because then if people don't
#  like the effects of your plugin they can remove all of them by
#  deleting one file.  The toggle-item itself works fine.
# The prolixity of `quarkpy.mapoptions' could be reduced by using
#  `import X from mapoptions' statements (without ""'s & #)as follows:
#""from quarkpy.mapoptions import *"" and
#""items.append(toggleitem("&Axis XYZ letter indicator in view windows",
#"AxisXYZ", (1,1),
#      hint="|Display the X Y or Z indicator letter per view to associate #the rotation menu buttons. These are for reference only and are not #selectable with the mouse."))""

# But I don't think that would be worthwhile, 
#  so we'll just use the long version below insted:
#


XYZitem = quarkpy.mapoptions.toggleitem("&Axis XYZ letter indicator in view windows", "AxisXYZ", (1,1),
      hint="|Axis XYZ letter indicator in view windows:\n\nThis display s the X Y or Z indicator letter per view to associate the rotation menu buttons. These are for reference only and are not selectable with the mouse.|intro.mapeditor.menu.html#optionsmenu")

quarkpy.mapoptions.items.append(XYZitem)
for menitem, keytag in [(XYZitem, "AxisXYZ")]:
    MapHotKey(keytag,menitem,quarkpy.mapoptions)

# Get the actual icons, no reason to do this more than once.
# Done by the loadimages function and the required augments.

#
# This part is a magical incantation.
# First the normal arguments for
#  finishdrawing, then the oldfinish=... stuff,
#  which has the effect of storing the current
#  finishdrawing method inside this function as
#  the value of the oldfinish variable.
# These def statements are executed as the plugins are being
#  loaded, but not reexecuted in later operations
#  of the map editor, only the functions they define are.

    # Why not see what the clientarea produces.
    # Look at the console to find out.
    #
#    debug('area: '+`view.clientarea`)

    #
    # Below ties this function to the toggel button
    #  in the Option menu.

# There is still the problem that when the view is panned, the old image is not erased, we
#   need to find out how the red lines are drawn, and how grey-out-of-view really works,
#   to learn how to stop this.  The images persist only in the view that's actually being
#   dragged on, but flicker in the others, which looks unprofessional, whereas the
#   red line is rock solid.
