Spin Control
After some soul-searching I have made a decision to create my own spin control. It turned out to be much easier than to mold the JSpinner to my requirements. Key solution elements:
- TSpinBox - my own spin control. Implemented as a composite control.
- Consists of a JTextField, and 2 TButtons.
- TButtons are layed out using a GridBagLayout (I am sure there must be a better way)
- TButtons are given special borders (small insets to make them fit nicely)
- TButtons are not focusable
- Implemented a hand-drawn ArrowIcon for the buttons
- ISpinBoxModel my own model for the TSpinBox
- Provided by IFormatter
- Extends the SpinnerModel interface, but adds spinUp, spinDown methods that actually change the value and alert all listeners
- First class to implement this is the SelectListModel: now it sends updates to spin ChangeEvent listeners (whenever the current slected value is not null) and provides the ability to navigate by spin.
