|
The QgsLayerTreeMapCanvasBridge class takes care of updates of layer set
|
|
for 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.
