Pardon the remailing, but I would really appreciate some feedback on this
from the GTK folk. I am happy to do the work to fix this problem, but its
not worth it if its not going to be accepted into the mainstream GTK+.

Yes, but as I think you understand, this also involves knowing the
specific signal connection(s) I want to block. I can't know that.
All I really want is a way to set a button to be "active" without
making it appear that there was user interaction.
The error, I think, is that toggle buttons have 2 signals, but anytime
you generate 1, you also generate the other. It seemed to me from
reading the docs that one could connect to "toggled" instead of
"clicked", and would then *every* change to the button
state. Alternatively, one could connect to "clicked", and see only
those changes caused by a mouse click.
Instead, the function that handles a pure toggle causes "clicked" to
be sent. This seems like a mistake to me. The button has not been
clicked, its been toggled, and so you're sending the wrong signal ...
"clicked" should be reserved for the completion of a button release

Yes, indeed it would. Owen, etc: if someone writes this (these?) will
you accept them into GTK ?
