using the blend function with a solid color image (bg color) and your
image will work, a simple loop changing the alpha value is all you
need. In my experience this is pretty fast. Check the documentation
for details.

Is there a widget method that returns whether a widget is
pack()-ed or unpacked?
The same question applies to widget's placed with the grid() or
place() layout managers.

Another way to control visibility might be to size a control/widget a
height/width of 0,0.
But Tkinter ignores this type of size request. (It does accept a size
request of 1,1, but in the case of Frame, im

Michael,
Thanks for the pack_forget() implementation and for the confirmation
that one should use grid vs. pack for scenarios that require
showing/hiding widgets.

Look at:
w.winfo_ismapped()
...Note that if a widget IS packed, but the parent (or some ancestor)
is not, this will return False.
w.winfo_manager()
-- will return "" if the widget is not packed/gridded etc.,
disregarding whether the parent is not packed.
Otherwise returns info on how it is plac
If you are placing a row of widgets into a frame, with pack you
don't have to keep track of which column you are up to, just
pack them one after the other.

Well, if you convert the image to a numpy array then you can call some C
functions on it so it's not that slow.
Once you've got it in a numpy array, you can use numpy to manipulate it
-- you're unlikely to need C.

Another option is to use Rapyd-TK (http://www.bitflipper.ca/rapyd/). It only
uses pack but it makes it trivially easy to add additional frames and it also
makes it really easy to rearrange the layout of your widgets, something not
easy with pack or grid by themselves.
