All pointer based methods have been removed.
Now we have only:
void setGeometry( const QgsGeometry& geom )
and
QgsGeometry geometry() const
Benefits include avoiding a whole lot of tricky pointer lifetime
issues, potential memory leaks, and finally closing #777, which
has survived for over 9 years!...
Impacts on PyQGIS code:
- no more need for the messy
g = QgsGeometry( feature.geometry() )
workaround, just use g = feature.geometry() instead
- IMPORTANT: you can no longer test whether a feature has geometry
using `if f.geometry():`, since QgsFeature::geometry() will
*always* return an object. Instead, use
`if not f.geometry().isEmpty():`, or preferably the new method
`if not f.hasGeometry():`
Fix#777
And rename to QgsUnitTypes::RenderUnits. This enum is used in
much more contexts than just symbols, so QgsUnitTypes is a
better fit for it.
All methods which previously accepted QgsSymbolV2::OutputUnit
parameters or QgsSymbolV2::OutputUnitList parameters now take
QgsUnitTypes::RenderUnit or QgsUnitTypes::RenderUnitList
parameters respectively.
This change consolidates more unit handling and conversion into
QgsUnitTypes.
Additionally, UnknownUnit was renamed to UnknownDistanceUnit.
All methods which accepted QGis::UnitType parameters have been
updated to take QgsUnitTypes::DistanceUnit instead.
ALso remove the unit handling methods toLiteral, fromLiteral, tr,
fromTr, and fromUnitToUnitFactor from QGis. Their corresponding
counterparts in QgsUnitTypes should be used instead.
This adds the ability for users to set whether a user created
color scheme should show up in the color button drop-down menus.
It's accessed through the color picker dialog, on the lists tab.
Just add a new color scheme, then from the scheme menu tick the
new "show in buttons" option.
Handy if you have sets of common palettes and want them to be
instantly available through the color menu.
- rename methods with XML to Xml, CRS to Crs, WMS to Wms, ID to Id
- rename methods with SRS to Crs
- rename methods with abbreviations like "dest" to "destination"
- rename methods with abbreviations like "src" to "source"
QgsNumericSortTreeWidgetItem had a giant TODO saying "make it work".
This makes it work, and adds some other useful features like
being able to specify custom sort value and force items to always
sort on top.
Clean up API. Remove QgsPanelWidgetPage - no longer needed
QgsPanelWidgetStack widget manages back button and breadcrumb.
QgsPanelWidget manages state of active widget.
This creates an action column widget when the widget is rendered for the
first time.
The original approach was to create an image and render the buffered
image onto the cell until the first mouse action triggered the creation
of the real widget. This led to several rendering problems and triggered
some strange ownership issues with crashes under certain situations.
