Instead of copyign a pre-existing .db shipped with QGIS, create
a new .db and import an .xml file containing our default symbols.
On the UX front, the main benefit is being able to ship with
pre-defined tags and favorite flags for the default symbols.
On the developer side, it means we get rid of the requirement
to maintain both an .xml and a binary .db in the source tree.
We also say aurevoir to the symbol_xml2db.py script and the
need to update the (obsolete) script every time we add a new
feature to QgsStyle.
- create a dedicated set of buttons for addition of tags and smartgroups
to make those actions more visible as well as getting rid of th need to
select a tag/smartgroup to create those (turns out to be quite confusing
for newcomers)
- move UI elements around, regroup {add,remove,edit} symbol buttons to
harmonize with other parts of QGIS; the elements' placement feels much
more natural now
- 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
Now the dialogs use a copy of the ramp, and the edited
ramp is retrieved by calling ramp() on the dialog after
it is executed.
Avoids pointer lifetime issues by storing and working
on a ramp pointer which the dialog does not have ownership
on.
Also fix a bunch of leaks relating to cloning color ramps.
QgsVectorColorRamp -> QgsColorRamp
QgsVectorGradientColorRamp -> QgsGradientColorRamp
QgsRandomColors -> QgsRandomColorRamp
QgsRandomColorRamp -> QgsLimitedRandomColorRamp
QgsVectorColorBrewerColorRamp -> QgsColorBrewerColorRamp
These color ramps are used throughout all of QGIS (not
just in vector symbology) and the current names are
misleading.
