Detailed Description

Owner of the canonical selection set for one SWMM project.

The four selection modes follow the QGIS / ArcGIS Pro vocabulary:

• Replace — discard the current selection and use refs as the new one.
• Add — union with the current selection.
• Toggle — flip each ref's membership (selected ↔ unselected).
• Subtract — remove each ref from the current selection.

selectionChanged(current, added, removed) is emitted whenever the set changes; the added and removed sets let subscribers do incremental updates instead of diffing their own copy of current.

Member Function Documentation

clear()

void SelectionManager::clear

(

)

Drop everything. Equivalent to select({}, Replace).

contains()

bool SelectionManager::contains ( const SWMMObjectRef &  ref ) const

inline

True if ref is in the current selection.

isEmpty()

bool SelectionManager::isEmpty ( ) const

inline

select() [1/2]

void SelectionManager::select	(	const QSet< SWMMObjectRef > &	refs,
		Mode	mode = Replace
	)

Apply refs to the current selection using mode.

Here is the caller graph for this function:

select() [2/2]

void SelectionManager::select	(	const SWMMObjectRef &	ref,
		Mode	mode = Replace
	)

Convenience overload for a single ref.

Here is the call graph for this function:

selection()

const QSet< SWMMObjectRef > & SelectionManager::selection ( ) const

inline

Read-only view of the current selection.

selectionChanged

void SelectionManager::selectionChanged ( const QSet< SWMMObjectRef > &  current, const QSet< SWMMObjectRef > &  added, const QSet< SWMMObjectRef > &  removed  )

signal

Emitted on every set change. added / removed are disjoint and convey the delta from the previous selection.

Here is the caller graph for this function:

size()

int SelectionManager::size ( ) const
