[PATCH shared-cd v1 5/9] Add empty CD entry to usb-device-widget, create shared CD when toggled

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Alexander Nezhinsky <anezhins@xxxxxxxxxx>

The empty CD entry is a placeholder and appears every time the widget is created.
When it is toggled, a file chooser dialog is popped up. If a file or device is
selected, a new CD device is created. The new CD device is auto-connected.

This device is communicated to the widget through the 'device-added' signal.
The list entry responsible for the new device corresponds to the entity
provided by usb-device-manager. The empty CD entry is automatically moved to
the top of the list.
