|
||||
should now call QgsCoordinateReferenceSystem::invalidateCache() and QgsCoordinateTransformCache::instance()->invalidateCrs( authid ).
|
||||
- QgsHttpTransaction. This class was outdated and code should be ported to native Qt or Python implementations.
|
||||
- QgsLabel and QgsLabelAttributes. Replaced by labeling based on PAL library, see QgsLabelingEngineV2.
|
||||
- QgsLegendInterface was removed. It was replaced by layer tree API (QgsLayerTreeNode class and others).
|
||||
Methods that deal with custom actions in main window's layer tree context menu were moved to QgisInterface:
|
||||
- addLegendLayerAction() moved to QgisInterface::addCustomActionForLayerType()
|
||||
- addLegendLayerActionForLayer() moved to QgisInterface::addCustomActionForLayer()
|
||||
- removeLegendLayerAction() moved to QgisInterface::removeCustomActionForLayerType()
|
||||
- QgsLegendModel was removed.
|
||||
- QgsMapCanvasMap. It is an internal class used by map canvas.
|
||||
- QgsMapRenderer. It has been replaced by QgsMapRendererJob with subclasses and QgsMapSettings.
