<Stn:KeyboardButton Name="RejectKeyboardButton"
Description
The KeyboardButton control is a button that is not presented on the display.
This button is used for mapping of keys in the piezo keyboard in the keyboard definition and also for creating buttons that are invisible, but still active, in the user interface.
This is the normal control used in the CWT 104 and CWT Compact Classic terminals because these products do not have any software controlled buttons on the sides or below of the display.
The KeyboardButton control uses the ButtonLocationName as a reference from the keyboard mapping. See Key mapping for information on how keys are mapped to positions and different functionality in the keyboard definition.

The values for the properties for the KeyboardButton element depend on the CWT model used. See the applicable section in Key mapping for more details.

Control information
See Key mapping for definition of click actions that can be used with the KeyboardButton control (same as those used for button control).
Example
This example defines a KeyboardButton control used as a reject button when the button is not rendered to the display (the normal case for the CWT 104 and CWT Compact Classic).
ButtonLocationName is still used for definitions of KeyboardButtons inside panels for reference from the keyboard definition. The click action is “OnReject” because the button shall act as a reject button to cancel active purchases. The Text property is not defined because nothing will be presented on the display when a KeyboardButton control is used:
<Stn:KeyboardButton Name="RejectKeyboardButton"
Text=""
Click="OnReject"
ButtonLocationName="LeftFour"/>
