ola::plugin::usbdmx::WidgetFactory Class Reference

Detailed Description

Creates new Widget objects to represent DMX USB hardware.

WidgetFactories are called when new USB devices are located. By inspecting the device's vendor and product ID, they may choose to create a new Widget object. The WidgetFactory then calls the WidgetObserver object to indicate a new Widget has been added.

When a USB device is removed, the factory that created a Widget from the device has it's DeviceRemoved() method called. The factory should then invoke WidgetRemoved on the observer object.
