* Many modules: fixes for new, stricter, argument passing rules (most changes were automatic ones -- not all of this is tested!). * gwin.py: now uses mainloop.py for its main loop and window admin. * mainloop.py: always call dispatch() with event as a tuple! * Fix bug in pdb's 'clear' command -- don't set the bpt but clear it!

# A FormSplit lets you place its children exactly where you want them
|
|
# (including silly places!).
|
|
# It does no explicit geometry management except moving its children
|
|
# when it is moved.
|
|
# The interface to place children is as follows.
|
|
# Before you add a child, you may specify its (left, top) position
|
|
# relative to the FormSplit. If you don't specify a position for
|
|
# a child, it goes right below the previous child; the first child
|
|
# goes to (0, 0) by default.
|
|
# NB: This places data attributes named form_* on its children.
|
|
# XXX Yes, I know, there should be options to do all sorts of relative
|
|
# placement, but for now this will do.
