How to set up QSpinbox increment bigger than +1?

In different areas of program i need to set different increment somewhere by +1 and somewehere by +2 or more. How to do this?

Solution

  • Use setSingleStep() method:

    This property holds the step value.

    When the user uses the arrows to change the spin box's value the value will be incremented/decremented by the amount of the singleStep. The default value is 1. Setting a singleStep value of less than 0 does nothing.

    spinBox->setSingleStep(2);
