IDataSource.GetList()

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.

+ + + + + + + + + + + + + + + + + + + + + +
