FPicker class
A generic picker that allows an item to be selected. It is composed of one or more FPickerWheels, optionally, with separators between those wheels.
Recommended for touch devices.
The picker supports arrow key navigation:
- Up/Down arrows: Increment/decrement selected value
- Left/Right arrows: Move between wheels
See:
- https://forui.dev/docs/form/picker for working examples.
- FPickerController for controlling a picker.
- FPickerWheel for customizing a picker's individual wheel.
- FPickerStyle for customizing a picker's appearance.
