static int countMapLayerInTree( QgsLayerTreeNode *tree, QgsMapLayer *layer );
|
|
%Docstring
|
|
Returns how many occurrences of a map layer are there in a layer tree.
|
|
In normal situations there is at most one occurrence, but sometimes there
|
|
may be temporarily more: for example, during drag&drop, upon drop a new layer
|
|
node is created while the original dragged node is still in the tree, resulting
|
|
in two occurrences.
|
|
|
|
This is useful when deciding whether to start or stop listening to a signal
|
|
of a map layer within a layer tree and only connecting/disconnecting when
|
|
there is only one occurrence of that layer.
