Program Interaction 

COM Support

 

The PxPlus COM interface allows you to integrate external components produced by third-party vendors into your MS Windows-based PxPlus application (e.g. progress bar, spreadsheet, browser, or calendar). This interface is used to obtain information about, as well as access to, the internal properties and methods of the Component Object Model (COM) control being used. These types of controls are now typically based on Windows ActiveX vs. the older OLE control technology (OCX).

NOMADS uses the COM Control Properties dialogue to include a variety of ready-made Windows components in your panels. It supports method calls, properties, event handling, as well as Post-Create logic.

To add a COM control to a NOMADS panel, see Adding a COM Control.

To define a COM control once it has been added to a panel, see Defining a COM Control.

For information on handling events for a COM control, see Handling Events.

Note:
As of PxPlus 2017, a new Chromium Browser Object was added that allows you to embed a Chromium Browser into PxPlus windows. This object can be used to display a Web page, execute JavaScript, and subscribe to browser events. The Chromium Browser was developed as an alternative to the Microsoft Web Browser (Shell Explorer).
