Hi there,

I created a simple GUI Application using QT Creator 2.6 and MSVC2010 with CDB on a Win7 SP1 32-Bit system.

The QUI was created by QT Designer and has a doubleSpinBox. I setup the slot
Qt Code:
  1. valueChanged(double)
To copy to clipboard, switch view to plain text mode 
of the doubleSpinBox. The slot is connected via
Qt Code:
  1. connectSlotsByName
To copy to clipboard, switch view to plain text mode 
.

Everything works fine, but if I set a breakpoint in the slot
Qt Code:
  1. doubleSpinBox_valueChanged(double arg1)
  2. {
  3. }
To copy to clipboard, switch view to plain text mode 
there is a strange behaviour:

On a click on the arrows of the doubleSpinbox the slot
Qt Code:
  1. doubleSpinBox_valueChanged(double arg1)
To copy to clipboard, switch view to plain text mode 
is called TWICE and of course the value-property of the doubleSpinBox is incremented/decremented twice!
I verified this by adding a
Qt Code:
  1. qDebug << "doubleSpinBox_valueChanged hit"
To copy to clipboard, switch view to plain text mode 
to the slot.




Is this a known issue?

Thanks for your help in advance!
