What makes the PictureBox any easier to draw on than anything else?

You don't even need a Form. You can just create a Control sub-class of
your own. Or you can drop a Panel instance into the Form and subscribe
to its Paint event to draw into that (the Panel has the nice quality
that it's very simple, has no visual elements of its own, but is still a
full-fledged control that can be manipulated in the Designer�in other
words, it's pretty much the simplest control available, short of just
writing one's own Control sub-class).

Apparently I haven't been clear. I'm talking about for testing and learning
purposes ONLY. I'm not suggestion any implementation. And for learning, it
seems to me far easier to just create a new Windows Forms project, slap a
PictureBox on it, and draw. Or just draw on the form. Your suggestion about
creating your own custom control seems like it's more for a final product
than simply playing with the Graphics object.

You don't need a special control in order to make your own painting "per
item" with a list box since setting the DrawMode property to OwnerDrawFixe
of OwnerDrawVariable would allow listbox_DrawItem event to fire, with an
appropriate graphical environment.

pages 362-365 supply two examples (one with fixed height, one with variable
height, per item (listbox_MeasureItem event is then involved too, in this
last case)).

Nevertheless, that doesn't answer my question. Even for "testing and
learning purposes", what makes the PictureBox class easier to use or
otherwise a superior choice over, for example, the Panel class?

If you've got an image to display and don't want to use DrawImage()
yourself, then sure�PictureBox seems like a fine choice. But for simply
drawing, it seems like overkill to me. Why do you feel it's better than
other choices available?
