Member Function Documentation

columnCount()

int MeshAttributeTableModel::columnCount ( const QModelIndex &  parent = {} ) const

override

columnSpecs()

QList< openswmmvis::ColumnSpec > MeshAttributeTableModel::columnSpecs ( ) const

inline

Per-column metadata — the panel installs delegates from this, exactly as it does for SWMMAttributeTableModel.

data()

QVariant MeshAttributeTableModel::data ( const QModelIndex &  index, int  role = Qt::DisplayRole  ) const

override

Here is the call graph for this function:

elementExtent()

QRectF MeshAttributeTableModel::elementExtent	(	int	row,
		bool *	ok = nullptr
	)		const

Bounding box of row's element in the layer's own (map) coordinates — a degenerate point for a vertex, the segment for an edge, the triangle bbox for a cell. ok reports whether the row resolved; a vertex sitting exactly at the origin is a legitimate zero-size rect, so the rect alone cannot signal failure.

Here is the call graph for this function:

flags()

Qt::ItemFlags MeshAttributeTableModel::flags ( const QModelIndex &  index ) const

override

Here is the caller graph for this function:

headerData()

QVariant MeshAttributeTableModel::headerData ( int  section, Qt::Orientation  orientation, int  role = Qt::DisplayRole  ) const

override

kind()

Kind MeshAttributeTableModel::kind ( ) const

inline

Here is the caller graph for this function:

layer()

SWMM2DMeshLayer * MeshAttributeTableModel::layer ( ) const

inline

Here is the caller graph for this function:

objectEdited

void MeshAttributeTableModel::objectEdited ( const QString &  refName )

signal

Emitted after a user-initiated cell edit commits, carrying the element's MeshObjectRef name. Distinct from dataChanged so listeners can tell a user edit from a synthetic refresh and avoid feedback loops — the same convention SWMMAttributeTableModel::objectEdited follows.

Here is the caller graph for this function:

refForRow()

SWMMObjectRef MeshAttributeTableModel::refForRow

(

int

row

)

const

Selection-bus ref naming the element on row, or an invalid ref.

Here is the call graph for this function:

Here is the caller graph for this function:

reload

void MeshAttributeTableModel::reload ( )

slot

Full reload — rebuilds the edge row index and resets the model.

rowCount()

int MeshAttributeTableModel::rowCount ( const QModelIndex &  parent = {} ) const

override

Here is the caller graph for this function:

rowForRef()

int MeshAttributeTableModel::rowForRef

(

const SWMMObjectRef &

ref

)

const

Inverse of refForRow. For an interior edge, EITHER slot of the pair resolves to the single row that represents it. -1 when the ref names a different layer, a different kind, or an element that is gone.

Here is the call graph for this function:

setCanvas()

void MeshAttributeTableModel::setCanvas

(

MapCanvas *

canvas

)

Canvas whose MapUndoStack the edits are pushed onto. Null ⇒ edits still apply, just unundoably (the push helpers' headless path). Out-of-line so this header does not have to pull in MapCanvas.

Here is the caller graph for this function:

setData()

bool MeshAttributeTableModel::setData ( const QModelIndex &  index, const QVariant &  value, int  role = Qt::EditRole  )

override

Here is the call graph for this function:

setModelLayer()

void MeshAttributeTableModel::setModelLayer

(

SWMMModelLayer *

layer

)

The SWMM model this mesh is coupled to. Supplies the candidate lists behind the picker columns — coupled node, BC time series, BC rating curve — so those cells can only ever name an object that exists. Without it those columns fall back to plain text entry.

Here is the call graph for this function:

Here is the caller graph for this function:

setSource()

void MeshAttributeTableModel::setSource	(	SWMM2DMeshLayer *	layer,
		Kind	kind
	)

Bind the model to a (layer, kind) pair; rebuilds the column schema and the edge row index, then resets. Pass a null layer to clear.

Here is the call graph for this function:
