## Why do we have to prevent TimerEvents reaching the SpinBoxes?
#
# Sometimes clicking a SpinBox once caused the value to increase by
# two. This is why:
#
# When a MouseClicked event is received by the SpinBox it fires a timerevent to control
# the repeated increase of the value as long as the mouse button is pressed. The timer
# is killed when it receives a MouseRelease event. If a slot connected to the valueChanged
# signal of the SpinBox takes to long to process the signal the mouse release
# and timer events get queued up and sometimes the timer event reaches the widget before
# the mouse release event. That's why it increases the value by another step. To prevent
# this we are blocking the timer events at the cost of no autorepeat anymore.
