layertreecategories.h File Reference

Pure category-bucketing helpers extracted from layertreepanel.cpp (Slice LTR-2026-05-30) so the mapping can be unit-tested headlessly without standing up a MapCanvas / OpenSWMMVisLayer object graph. More...

Classes
struct	openswmmvis::ui::CategoryInfo
	User-visible label + Qt resource alias for a category. Returned by categoryInfo(); the strings are static (resource aliases under :/swmmvis/ are compile-time constants). More...

Namespaces
namespace	openswmmvis
namespace	openswmmvis::ui

Enumerations
enum	openswmmvis::ui::CategoryId {   openswmmvis::ui::CatSwmm = 0 ,   openswmmvis::ui::CatMeshes ,   openswmmvis::ui::CatSwmm1DOutputs ,   openswmmvis::ui::CatSwmm2DOutputs ,   openswmmvis::ui::CatFeatureLayers ,   openswmmvis::ui::CatRasterLayers ,   openswmmvis::ui::CatBasemaps ,   openswmmvis::ui::CatTables ,   openswmmvis::ui::CatCount }
	Top-level layer-tree groups. More...
enum class	openswmmvis::ui::LayerTypeOrdinal : int {   openswmmvis::ui::SWMMDefaultLayer = 0 ,   openswmmvis::ui::SWMMModelLayer = 1 ,   openswmmvis::ui::SWMMResultsLayer = 2 ,   openswmmvis::ui::SWMMGISLayer = 3 ,   openswmmvis::ui::SWMMVectorLayer = 4 ,   openswmmvis::ui::SWMMRasterLayer = 5 ,   openswmmvis::ui::SWMMImageryLayer = 6 ,   openswmmvis::ui::SWMMTabularDataLayer = 7 ,   openswmmvis::ui::SWMMTabularyTimeSeriesLayer = 8 ,   openswmmvis::ui::SWMMSubProjectLayer = 9 ,   openswmmvis::ui::SWMMWMSLayer = 10 ,   openswmmvis::ui::SWMMWMTSLayer = 11 ,   openswmmvis::ui::SWMM2DMeshLayer = 12 ,   openswmmvis::ui::SWMM2DResultsLayer = 13 ,   openswmmvis::ui::SWMMAnnotationLayer = 14 }
	Mirror of OpenSWMMVisLayer::OpenSWMMVisLayerType — same ordinals, no Qt include cost. Used by tests so they can call categoryForLayerType() without pulling openswmmvislayer.h. More...

Functions
CategoryId	openswmmvis::ui::categoryForLayerType (int layerTypeOrdinal)
	Maps a layer-type ordinal to its tree category.
CategoryId	openswmmvis::ui::categoryForLayerType (LayerTypeOrdinal t)
	Convenience overload taking the typed ordinal directly.
CategoryInfo	openswmmvis::ui::categoryInfo (CategoryId id)
	Returns the display label + icon alias for a category.

Variables
constexpr int	openswmmvis::ui::kDefaultCategoryDisplayOrder [CatCount]
	Default top-to-bottom order of the category groups in the layer tree AND in the canvas paint stack (index 0 = top of tree = drawn last). Results groups sit on top because they overlay the model / mesh for analysis; tables sit at the bottom.

The header has no Qt dependency and no link dependency on layers/openswmmvislayer.h. Layer types are passed as plain int (matching the underlying OpenSWMMVisLayer::OpenSWMMVisLayerType enum values, which are stable across releases per openswmmvislayer.h's serialization contract). The mirror enum LayerTypeOrdinal below lets test code reference the same ordinals without pulling Qt — a static_assert in the .cpp checks that the mirror stays in lockstep with the source.
