Description

This class serves as a parent class of resources for numeric widgets, and is not normally instantiated. It joins a PtText widget with a PtUpDown widget, creating a text-entry box for numbers that can be incremented or decremented with small arrow-shaped buttons.

For detailed information, please refer to PtNumeric in the Photon documentation.
