Commands reference guide

This topic describes commands that can be used to create custom buttons for the Custom Commands pane or the Task Pads pane.

The following commands can be used to program the functionality of both POS Task Pads and Custom POS Buttons. You must configure Task Pads and Custom Buttons in Store Manager.

Starting with release 3.11.0 you can program Task Pads or Custom Buttons to execute a chain of commands when the button is clicked by adding a semicolon (;) between commands. For example, you might create a chain of commands to discount a transaction (command 1) and then automatically select a discount reason code (command 2). There is no limit to the number of commands in a chain. However, the commands should be chained together to follow a logical transaction process.

CUSTOM ACTION COMMAND

Use this command to enable custom functionality in a POS Extension using a custom button (or a task pad button).

Command

Description

CustomActionCommand

Example: CustomActionCommand "param1|param2|param3" Essentially, this command fires up an event in the POS, and passes a parameter to it. Your extension will listen to that event, and when it is fired, check the parameter to see if it is the "own" parameter (which will be processed) or a "foreign" one (which will be ignored). The command/event is available equally to all extensions, so it is important for the extension to distinguish by looking at the parameter. Please review the demo project in the SDK: C:\Program Files (x86)\Retail Hero\RMH POS\RMH POS SDK\SDK_POS.ZIP\RMHDemoExtension-Native\RMHDemoExtension (or the Telerik version). Check the area "Custom Button Handling". The comment in the project reads: // The custom buttons could use any string parameter (but only one per command - XAML allows only one command parameter) // Multiple parameters could be passed as a single string with separators, such as: "parameter1|parameter2|parameter3" // It is recommended to use GUIDs as parameter. That will make sure that different extensions don't mix-up handling // the same custom action event // In the CustomPanel xaml, the Custom Action 1 and 2 buttons use guids as parameters // Each custom button raises the same even, but passes a different parameter // That's how multiple extensions know which event is "their" and ignore all others. //Guid for Custom Action 1 button: DEDE0403-5C7A-4A84-BB75-F1DD0D914F4D //Guid for Custom Action 2 button: 71D09398-1A5C-4CB4-9738-1584B61483F1 Although this explanation is a bit outdated (it talks about CustomPanel.xaml while since RMH version 3.2 we handle the custom buttons by creating them in Store Manager, not via the XAML modification), it still applies in principle no matter how the button is created. In fact, in your custom button you can use any "string" parameter with your command, but we recommend using generated GUIDs as that would prevent the possible extension "clash" if two or more extensions happen to use the same string parameter. See also p.19 in RMH_SDKProjects_v1_CL.pdf (in the POS SDK folder).
