|
|
* The TaskbarManager allows interaction with the ScummVM application icon:
|
|
* - in the taskbar on Windows 7 and later
|
|
* - in the launcher for Unity
|
|
* - in the dock on MacOSX
|
|
* - ...
|
|
*
|
|
* This allows GUI code and engines to display a progress bar, an overlay icon and/or count
|
|
* associated with the ScummVM icon as well as add the started engine to the recent items
|
|
* list (so that the user can start the engine directly in one click).
|
|
*
|
|
* Examples of use:
|
|
* - Track search progress and found engines when running the Mass Add dialog
|
|
* - Add an entry to the recent items when starting an engine
|
|
* - Show the current running engine icon as an overlay
|
|
*
|
|
* @note functionality will vary between supported platforms (due to API limitations)
|
|
* and some of the methods will just be no-ops or approximate the functionality
|
|
* as best as possible
