Thanks for the rapid response.

SEND_EVENT seems to just pass the event along to the XMANAGER event
handler for my menu, rather than opening up the pulldown menu. That
is, it yields different results than physically clicking on the
button. Maybe I'm sending the wrong event structure? Since I never
see the menubutton push events (the ones that open submenus) I don't
know what they look like. Interestingly (maybe) the event that I get
in my menu handler is not the same as the one that I am sending to the
button to try to "push it" -- the "handler" element is changed from my
button ID to my base ID.
I'm not sure what you mean by 'call your button event handler directly
from the draw widget event handler with an obviously fake "button"
event' ... communication between these two handlers isn't an issue,
instead I just don't know how to "push" the button and make it drop
down its submenu.
On a probably completely unrelated item, is there a way to
programmatically move the cursor around a draw window? I'd like to
make arrow key presses move the cursor in a draw window (to more
accurately move), and although I don't have a problem turning the
keypresses into mouse motion events, I can't seem to actually move the
cursor. Put the answers to these two questions together and you have
a way of making demos for people, by programmatically moving the
cursor up to menu items and then "pushing" them, to show the user what
to do.
Thanks again,
Eric
