Layers are handled internally by the class
IlvManagerLayer. Layers can be accessed by their index or by their
instance (a pointer to an
IlvManagerLayer
).
By default, a manager is created with one layer. However, you can
specify how many layers you want to create for a manager in the second
parameter of the
IlvManager
constructor.
Once the manager has been created, you can modify the
number of layers using the following methods:
void addLayer(int index)
void removeLayer(int index, boolean redraw)
and retrieve the number of layers with:
int getLayersCount()
