Within the attribute table, there is a new button to trigger actions
which are not based on individual features but instead on the whole layer.
Normally they will perform actions based on all features or the selection.
In addition to this, a lot of cleanup has been done.
- A new favorite grouping system was added, which the symbols list
widget defaults to
- The selected tag / smartgroup in the symbols list widget now
persists when switching layers (and across sessions)
- The symbols list widget will update the tag / smartgroup combo
box when users add / rename / remove categories
- Users can now directly tag, as well as add to favorites, symbols
while saving those to the style database
- To streamline style management, groups have been removed and
fully replaced by tags
- Tags have been integrated into the import/export user interface
The order of the elements is irrelevant and duplicate elements are unwanted. It
is therefore a perfect candidate for a set instead of a list. This prevents
filtering for duplicates manually be replacing some filer codes with (more
performant) builtin methods of QSet.
instead of individually setting map canvas, expression context, etc
Will make it more easy in future to add additional parameters
to the widget context
Groups nearby points into a single rendered marker symbol.
QgsPointDisplacementRenderer has been split into a new
pure virtual QgsPointDistanceRenderer base class which handles the
detection of clusters and grouping of points. The new cluster
renderer reuses this base class to avoid code duplication.
Additionally, some improvements have been made to the
displacement renderer, specifically:
- points are now assigned to the group which is "nearest" them,
rather then just assigning them first group within the search
distance. In some cases this was assigning features to a more
distant cluster, resulting in less predictable cluster patterns
- individual points are now correctly shown in their own
selection state
Lots of code cleanup + documentation too.
