class QgsLayerTreeMapCanvasBridge : QObject
{
%Docstring(signature="appended")
The :py:class:`QgsLayerTreeMapCanvasBridge` class takes care of updates
of layer set for :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.
