I did:
$ emacs -Q
C-h v double-click-fuzz RET
{click on "customize"}
{change "Double Click Fuzz" to 30}
{click on "Apply", verify that State changes to "SET for current
session only."}
{click on "Revert...", slightly moving the mouse [less than 30 px]
between button press and release}
Expected result: "Reset settings" popup appears.
Actual result: Nothing happens.
But you’re right, increasing double-click-fuzz has the desired effect in
other "clickable" places like Speedbar and Gnus Summary buffer. This is
great and just what I was looking for. Maybe widgets do not respect
double-click-fuzz for some reason?
I see this behaviour is explained in double-click-fuzz docstring ("This
variable is also the threshold for motion of the mouse to count as a
drag"). Too bad I couldn’t find that myself.
Thanks for your time.
