%Docstring(signature="appended")
|
|
Takes care of updates of layer sets for a :py:class:`QgsMapCanvas` from
|
|
a layer tree.
|
|
|
|
The class listens to the updates in the layer tree and updates the list
|
|
of layers for rendering whenever some layers are added, removed, or
|
|
their visibility changes.
|
|
|
|
The update of layers is not done immediately - it is postponed, so a
|
|
series of updates to the layer tree will trigger just one update of
|
|
canvas layers.
|
|
|
|
Also allows the client to override the default order of layers. This is
|
|
useful in advanced cases where the grouping in layer tree should be
|
|
independent from the actual order in the canvas.
