<TFT:UiTariffValueButton Id="1" MxStyle="{UiTariffValueButtonVisualStyle}" Location="100,580"/>
The user interface value button is triggering the calculation of the values for the parking ticket and the tariff’s value button is containing the values to be used. The number of buttons may or may not match the number of steps in the tariff. The tariff steps are incremental since the tariff engine will step until the amount or time match the value button that was pressed in the user interface.
There must exist a tariff with at least one value button for a user interface value button to be shown. The ’id’ property will be used for the matching between the tariff and the user interface.
If there are more buttons declared in the tariff than can be showed in the user interface, the button types Right and Left is used to scroll between sets of tariff buttons. The maxVisibleButtons property is then used as a threshold value for the Right button to be showed.
The last selected tariff button will change to a highlighted state in the user interface. Disabled, enabled and highlighted states has own image properties.
