The main window's layer tree view (ToC) gets support for indicators that are shown when a vector layer has a filter applied. This makes it easier for users to understand that they are looking at a subset of all data. Clicking the indicator's icon brings up query builder.
This adds a mini-framework for display of extra icons in layer tree views next to layer and group names. Tool tip text can be associated with indicators to give extra context for indicators. In addition, a signal gets emitted when user clicks indicators and custom actions can be defined. The idea is that indicators can be used in the future for a subtle reporting of various bits of information, for example:
- map layer with invalid geometries
- map layer with on-the-fly reprojection exceptions
- map layer has missing data source
- map layer with invalid CRS
