To enter data on POS terminals, you can use either a traditional keyboard that records mechanical strokes or an on-screen keyboard that appears on a sensor screen.
An on-screen (virtual) key is, functionally, an area on the sensor screen. These on-screen buttons are used:
as directional keys,
as numeric keys,
as buttons added to screen forms during configuration,
as items in selection tables of: menu groups and menu items, draft menu groups and draft menu items, payment methods, as well as to display commands in the main menu (to select terminal operating modes).
To display selection tables with buttons on the POS terminal screen, locate the GridButtons
option (in the Show
menu) within the device settings and assign this option the value True.
Show = ( GridButtons = True ... )
Initially, all buttons are displayed in the standard format created by the developer. You can edit the standard on-screen button image by specifying one of the pre-defined formats for it.
An On-screen button format has the following set of parameters: colour, size, text font characteristics, and relative positions of the text and the picture. Users can modify button formats on the basis of ready-made styles. These styles designate the relative positions of the picture and the text on a programmable button.
The on-screen button format is used in the and directories, in the directory, and in the directory.
The directory is used to manage the formats of buttons that are displayed on POS terminal screens.
