+# Keith Vetter 2003-03-21: this started out as a simple little program
+# but was so much fun that it grew and grew. So I apologize about the
+# size but I just couldn't resist sharing it.
+#
+# This is a whizzlet that does a Rube Goldberg type animation, the
+# design of which comes from an New Years e-card from IncrediMail.
+# That version had nice sound effects which I eschewed. On the other
+# hand, that version was in black and white (actually dark blue and
+# light blue) and this one is fully colorized.
+#
+# One thing I learned from this project is that drawing filled complex
+# objects on a canvas is really hard. More often than not I had to
+# draw each item twice--once with the desired fill color but no
+# outline, and once with no fill but with the outline. Another trick
+# is erasing by drawing with the background color. Having a flood fill
+# command would have been extremely helpful.
+#
+# Two wiki pages were extremely helpful: Drawing rounded rectangles
+# which I generalized into Drawing rounded polygons, and regular
+# polygons which allowed me to convert ovals and arcs into polygons
+# which could then be rotated (see Canvas Rotation). I also wrote
+# Named Colors to aid in the color selection.
+#
+# I could comment on the code, but it's just 26 state machines with
+# lots of canvas create and move calls.

+# popup -		If a menu has been popped up via tk_popup, this

+#			A grab is set on this widget.
+# relief -		Used to save the original relief of the current

+#-------------------------------------------------------------------------
+# Overall note:
+# This file is tricky because there are five different ways that menus
+# can be used:
+#
+# 1. As a pulldown from a menubutton. In this style, the variable
+#    tk::Priv(postedMb) identifies the posted menubutton.
+# 2. As a torn-off menu copied from some other menu.  In this style
+#    tk::Priv(postedMb) is empty, and menu's type is "tearoff".
+# 3. As an option menu, triggered from an option menubutton.  In this
+#    style tk::Priv(postedMb) identifies the posted menubutton.
+# 4. As a popup menu.  In this style tk::Priv(postedMb) is empty and
+#    the top-level menu's type is "normal".
+# 5. As a pulldown from a menubar. The variable tk::Priv(menubar) has
+#    the owning menubar, and the menu itself is of type "normal".
+#
+# The various binding procedures use the  state described above to
+# distinguish the various cases and take different actions in each
+# case.

+#			command to be executed.
+# char -		Character position on the line;  kept in order
+#			to allow moving up or down past short lines while
+#			still remembering the desired position.
+# mouseMoved -		Non-zero means the mouse has moved a significant
+#			amount since the button went down (so, for example,
+#			start dragging out a selection).
+# prevPos -		Used when moving up or down lines via the keyboard.
+#			Keeps track of the previous insert position, so
+#			we can distinguish a series of ups and downs, all
+#			in a row, from a new up or down.
+# selectMode -		The style of selection currently underway:
+#			char, word, or line.

+# Removed the following standard Tk bindings:
+#
+# <Control-space>, <Control-Shift-space>,
+# <Select>,  <Shift-Select>:
+#	Ttk entry widget doesn't use selection anchor.
+# <Insert>:
+#	Inserts PRIMARY selection (on non-Windows platforms).
+#	This is inconsistent with typical platform bindings.
+# <Double-Shift-Button-1>, <Triple-Shift-Button-1>:
+#	These don't do the right thing to start with.
+# <Meta-b>, <Meta-d>, <Meta-f>,
+# <Meta-BackSpace>, <Meta-Delete>:
+#	Judgment call.  If <Meta> happens to be assigned to the Alt key,
+#	these could conflict with application accelerators.
+#	(Plus, who has a Meta key these days?)
+# <Control-t>:
+#	Another judgment call.  If anyone misses this, let me know
+#	and I'll put it back.

+#
+# Pulldown: Press menubutton, drag over menu, release to activate menu entry
+# Popdown: Click menubutton to post menu
+# Keyboard: <space> or accelerator key to post menu
+#
+# (In addition, when menu system is active, "dropdown" -- menu posts
+# on mouse-over.  Ttk menubuttons don't implement this).
+#
+# For keyboard and popdown mode, we hand off to tk_popup and let
+# the built-in Tk bindings handle the rest of the interaction.
+#
+# ON X11:
+#
+# Standard Tk menubuttons use a global grab on the menubutton.
+# This won't work for Ttk menubuttons in pulldown mode,
+# since we need to process the final <ButtonRelease> event,
+# and this might be delivered to the menu.  So instead we
+# rely on the passive grab that occurs on <Button> events,
+# and transition to popdown mode when the mouse is released
+# or dragged outside the menubutton.
+#
+# ON WINDOWS:
+#
+# I'm not sure what the hell is going on here.  [$menu post] apparently
+# sets up some kind of internal grab for native menus.
+# On this platform, just use [tk_popup] for all menu actions.
