Detailed Description

The QgsLayerTreeModel class is model implementation for Qt item views framework.

The model can be used in any QTreeView, it is however recommended to use it with QgsLayerTreeView which brings additional functionality specific to layer tree handling.

The model listens to the changes in the layer tree and signals the changes as appropriate, so that any view that uses the model is updated accordingly.

Behavior of the model can be customized with flags. For example, whether to show legend or whether to allow changes to the layer tree.

Note: added in 2.4

Member Enumeration Documentation

◆ Flag

enum QgsLayerTreeModel::Flag

Enumerator
ShowLegend	Add legend nodes for layer nodes.
ShowSymbology	deprecated - use ShowLegend
ShowRasterPreviewIcon	Will use real preview of raster layer as icon (may be slow)
ShowLegendAsTree	For legends that support it, will show them in a tree instead of a list (needs also ShowLegend). Added in 2.8.
DeferredLegendInvalidation	defer legend model invalidation
UseEmbeddedWidgets	Layer nodes may optionally include extra embedded widgets (if used in QgsLayerTreeView). Added in 2.16.
AllowNodeReorder	Allow reordering with drag'n'drop.
AllowNodeRename	Allow renaming of groups and layers.
AllowNodeChangeVisibility	Allow user to set node visibility with a check box.
AllowLegendChangeState	Allow check boxes for legend nodes (if supported by layer's legend)
AllowSymbologyChangeState	deprecated - use AllowLegendChangeState
