How to disable the up/down buttons within the QDoubleSpinBox

Question

I have a QDoubleSpinBox in QT. I would like to conditionally disable the step up and/or down buttons. I am not sure how to do this.

I saw that in the QAbstractSpinBox there is a flag called StepEnabledFlag. But i am not sure how to set that.

Can anybody help me out with this.

Thanks Arjun

Answer 1

You need to create a QDoubleSpinBox subclass with a custom implementation of the step enabled function. (http://doc.trolltech.com/4.5/qabstractspinbox.html#stepEnabled)

Answer 2

Use QAbstractSpinBox::setButtonSymbols(). You can set one or both of the arrow buttons to be disabled.
