• simData library no longer uses Google Protobuf. Preferences, commands and properties are now defined with CXX classes. The new classes are similar to the Protobuf classes, but not backwards compatible. Reflection is done with a new class. See simData::Reflection for details. simData.proto, no longer directly used by the SIMDIS SDK, has been removed.
• simData::CategoryFilter removeName() and removeValue() now include string overloads for convenience, and removeName() now returns an error value.
• simData::CategoryNameManager now provides several new convenience wrappers that directly return vectors for category names, category name ints, all values in category, and all value ints in category.

• simQt::ViewerWidgetAdapter is a new widget based on osgQOpenGL's osgQOpenGLWindow class, which is based on QOpenGLWindow instead of QGLWidget.
• simUtil::Capabilities now includes checks for RAM and CPU count.
• simVis::ViewManager now can create a separate osgViewer::CompositeViewer for each top level main view it receives. Off by default, this feature allows it to cleanly support osgQOpenGL in some cases with multiple contexts. See examples QtDragAndDrop and QtDockableViews for cases where this can be useful.
• simVis::Viewer now supports an EMBEDDED flag when initializing, to avoid creating an internal graphics context.

Bug Fixes

• Colors now have their alpha values saved to INI format correctly when saving simQt::Settings.
• Image Icons with Icon Fast Draw mode enabled now return the correct bounds in Platform::getActualSize() and PlatformModel::getUnscaledIconBounds().
• Layer File Patterns now correctly includes GPKG (*.gpkg) in the list of GDAL-supported file extensions.

• simCore::Units::BAM now uses the correct toBase scalar.
• simData::CategoryFilter now better handles removing a "No Value" item in an "Unlisted Items" (exclude) filter by toggling it on. This counterintuitive behavior is due to the implicit/explicit relationship between these two items in category filter pages and breadcrumbs.
• simQt::CategoryTreeModel now correctly emits the dataChanged signal when filters are externally changed, fixing a minor display glitch.
• simQt::DockWidget now always restores tab icon for re-opened tabbed widgets.
• simQt::Settings::convertToInternalFormat() typo in method name corrected.
• simVis::FilteringOsgNotifyDecorator is a new decorator wrapper around an osg::NotifyHandler, allowing messages to be filtered by terms. A related utility simVis::installFilterOsgNotifyDecorator() with a default configuration to drop spam warnings from NVIDIA 571 drivers.

SIMDIS SDK 1.20

SIMDIS SDK changes since version 1.19

New Features

• GOGs that reference image files will attempt to create a new image file if necessary when serializing.

• simQt::DockWidget will now show on top of parent window if position initialization from settings fails.
• simVis::GOG defines GOG_PRECISION to specify recommended precision when serializing GOGs to stream.
• simVis::OverrideColor and associated platform preference overrideColorCombineMode support a new mode for an intensity gradient. This applies post-lighting and may provide a more consistent result than the Color Replace mode.
• simVis::Picker supports picking multiple entities at once.

Bug Fixes

• simQt::DockWidget now recenters over parent widget on display, if the dock widget is not visible on any screen.
• simQt::FileUtils simQt::FileUtils::isPathWritable() no longer creates the path automatically. To continue this behavior, call simCore::mkdir() first.
