PlayQueue QML Type
|Import Statement:||import QtIvi.Media 1.0|
The PlayQueue is a model which is used by the MediaPlayer to control the play order of PlayableItems.
It provides mechanisms for adding new items and managing the existing ones by removing or moving them around.
The PlayQueue can't be instantiated by its own and can only be retrieved through the MediaPlayer.
chunkSize : int
Holds the number of rows which are requested from the backend interface.
This property can be used to fine tune the loading performance.
Bigger chunks means less calls to the backend and to a potential IPC underneath, but more data to be transferred and probably longer waiting time until the request was finished.
count : int
Holds the current number of rows in this model.
currentIndex : int
Holds the index of the currently active track.
Use the get() method to retrieve more information about the active track.
fetchMoreThreshold : int
Holds the row delta to the end before the next chunk is loaded
This property can be used to fine tune the loading performance. When the threshold is reached the next chunk of rows are requested from the backend. How many rows are fetched can be defined by using the chunkSize property.
The threshold defines the number of rows before the cached rows ends.
loadingType : enumeration
Holds the currently used loading type used for loading the data.
Note: When changing this property the content will be reset.
This signal is emitted whenever the fetchMoreThreshold is reached and new data is requested from the backend.
Note: The corresponding handler is
insert(index, PlayableItem item)
Insert the item at the position index.
If the backend doesn't accept the provided item, this operation will end in a no op.
move(cur_index, int new_index)
Moves the item at position cur_index to the new position new_index the play queue.
