[Qt-interest] QStatemachine: Enter state and assignProperty() issue

This was my first thought too when i started seeing the issue.

I think I should call show() _before_ informing the widget callback
that its state has been entered and call hide() _after_ informing the
widget that we are about to leave the state.

This will help only if the connection to these signals is queued,
right? Otherwise connecting to these signals will be equivalent to
direct function call.

Hmmm, I'll check this.
