John, I think what this patch does is a great idea, but I have a problem
with the implementation.

As you can see QPopupMenu gets the submenu popup delay by calling
style().styleHint(QStyle::SH_PopupMenu_SubMenuPopupDelay, this).

The reason it does that is so that the widget style can specify the delay.
For example the Motif style has a 96 ms delay while the Windows style
has a 256 ms delay. On Windows I believe the style actually obtains this
value from the system registry, allowing Qt apps to honor the system
wide settings.

In KStyle we've taken advantage of this to make the delay configurable
for KDE styles. Try adding PopupMenuDelay = <num> to your
~/.qt/kstylerc file.

Your patch breaks these features.

Fredrik
