|
|
|
|
A map layer which consists of a set of child layers, where all component layers are rendered as a single
|
|
flattened object during map renders.
|
|
|
|
Child layers are never owned by :py:class:`QgsGroupLayer`. References to layers in a group are stored as weak
|
|
references only, which wills be automatically cleaned up whenever the linked child layer is deleted.

Sets the child ``layers`` contained by the group.

This method does not take ownership of the layers, but rather assigns them to the group. Layers should be already added to

the parent :py:class:`QgsProject` wherever appropriate.

Sets the current paint ``effect`` for the renderer.

void prepareLayersForRemovalFromGroup();
|

%Docstring
|
|
Prepares all child layers in the group prior to removal from the group.
|
|
|
|
This method should be called before removing a group layer from a project, to ensure
|
|
that the existing child layers are in a state which is compatible with non-group
|
|
layer children.
