Implement custom data models for spinners

Message 1 in thread

Hello!

I wonder if somebody can show me an example of how I can implement a 
custom datamodel for a QSpinBox. I have a set of valid numbers that the 
spinner should jump between when it is stepped up and down, and the 
valid number are NOT in a continuous range.

Regards,
Helge Fredriksen

Hi Helge,

QAbstractSpinBox has some virtual methods stepBy and validate which you 
should be able to reimplement to get the behaviour you need.
