Description:
The GetList method retrieves a list of media information
objects from the Media Gallery of the S60
device. Each object contains information about a single media file.
This is an asynchronous method.
Syntax:
result = so.IDataSource.GetList(criteria, callback);
Arguments:
criteria:
This is an object that specifies what media information is returned and how the returned information is sorted. For more information about the object properties and how to define them, see section Criteria for retrieving media information.
callback:
The callback argument is the name of the method
that is executed when GetList has results or status information
to return. You must define this method separately. Follow the instructions
in section Defining the callback handler for an asynchronous method to
define the callback method.
Return value:
The GetList method returns an object that contains
the initial return value for the asynchronous call it started (see the following
table). The actual media file information is returned by the callback method in the ReturnValue property of its result object.
The returned information is described in section Returned media information.
