Allows for live, dynamic heatmaps for point layers. Options include
specifying heatmap radius in pixels, mm or map units, choice of
color ramp, and a slider for selecting a tradeoff between render
speed and quality.
The multirenderchecker allows to have several images, each with its own set of
anomalies distributed in several subdirectories.
With the help of multiple reference images, it is possible to apply a color
tolerance to each of these
QToolButton. Features:
- context menu items have been moved to the attached menu button
- new gui widget QgsColorSwatchGrid, which displays a grid of colors
- new class for QgsColorScheme, which generates colors to show in a
color swatch grid
- new class QgsColorSchemeRegistry, with a global instance containing
default color schemes. QgsColorButtonV2 accepts a color scheme
registry, to control which schemes to show in the popup menu as
color swatch grids.
- color button can have a default color
- color button can also be quickly set to a totally transparent color
- c++ and python unit tests for all core components
- map layers have associated QgsMapLayerLegend instance
- QgsMapLayerLegend is interface for generation of legend with some default implementations
- QgsLayerTreeModelLegendNode is interface for representation of legend item in layer tree model with some default implementations
- New class QgsComposerObject, which both QgsComposerItem and QgsComposerMultiFrame
derive from. This class contains the framework for data defined composition properties.
- New class QgsComposerUtils, containing helpful static functions previously in QgsComposerItem
- Test suites for data defined settings in QgsComposerObject and functions in QgsComposerUtils
- Add support for reordering columns in a table (fix#5942)
- Add support for expression based columns
- Add support for setting column alignment (fix#2957)
- Add support for setting column header alignment
- Make sorting in tables correctly handle nulls, dates, times, locale aware string sorting
This work also paves the way for future expansion of attribute tables to allow for setting column widths, column colors, etc.
- Add QgsDataDefined class
- Add QgsDataDefinedButton class
- Add data defined Python support
- Add standalone SVG selector dialog to QgsSvgSelectorWidget class
- Fix for #4607, show only pertinent fields when setting a data defined value
- Fix for #5048 and #5049, data defined settings are literally used
- Fix for #5726, number formatting does not work for expressions
- Fix for #7755, using bufferSize to enable/disable label buffer is confusing
- Fix for #7779, labels do not register in label collision engine; and for #4719, inactive options in labeling dialog
- Prepare label text's expression upfront when preparing layer; makes rendering much faster
- Change name of 'feature obstacles' to appropriate terminology
