categoryAtTopRow()

SWMMModelLayer::Category SWMMObjectTreeModel::categoryAtTopRow

(

int

topRow

const

Which SWMMModelLayer::Category is rendered at top-level row topRow, or NumCategories if the row is out of range or the row is a data / divider row.

Here is the caller graph for this function:

columnCount()

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

override

data()

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

Here is the caller graph for this function:

dataCategoryAtTopRow()

SWMMModelLayer::DataCategory SWMMObjectTreeModel::dataCategoryAtTopRow

(

int

topRow

)

const

Slice BM.0 — which SWMMModelLayer::DataCategory is rendered at top-level row topRow, or NumDataCategories when out of range or the row is in another section.

dropMimeData()

bool SWMMObjectTreeModel::dropMimeData ( const QMimeData *  data, Qt::DropAction  action, int  row, int  column, const QModelIndex &  parent  )

Here is the caller graph for this function:

indexFor() [1/2]

QModelIndex SWMMObjectTreeModel::indexFor

(

const SWMMObjectRef &

ref

)

const

Convenience: model index for a selection-bus object. Walks the layer's name→(cat,row) map — O(1) hash lookup. Returns an invalid QModelIndex when the object is unknown.

Here is the call graph for this function:

indexFor() [2/2]

QModelIndex SWMMObjectTreeModel::indexFor	(	SWMMModelLayer::Category	c,
		int	row
	)		const

Model index for a specific leaf (category, row), or invalid if either is out of range / the category is hidden.

Here is the call graph for this function:

Here is the caller graph for this function:

mimeData()

QMimeData * SWMMObjectTreeModel::mimeData ( const QModelIndexList &  indexes ) const

override

Here is the call graph for this function:

mimeTypes()

QStringList SWMMObjectTreeModel::mimeTypes ( ) const

override

parent()

QModelIndex SWMMObjectTreeModel::parent ( const QModelIndex &  child ) const

override

Here is the call graph for this function:

reload

void SWMMObjectTreeModel::reload ( )

slot

Full reset — call when the layer's SoA has been replaced wholesale (model reload / CRS reproject / add-node that shifts the category counts).

Here is the caller graph for this function:

rowCount()

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

override

Here is the call graph for this function:

scheduleReload

void SWMMObjectTreeModel::scheduleReload ( )

slot

Coalescing wrapper — schedules a single reload() on the next event-loop turn no matter how many change signals fire this turn. Data-object mutations arrive in bursts (a registry rename fires remove+add pairs; bulk imports fire per object) and some fire BEFORE the mutation completes (providerAboutToBeRemoved), so the deferred reload both dedupes and reads post-mutation state.

Here is the call graph for this function:

Here is the caller graph for this function:

sectionAtTopRow()

SWMMObjectTreeModel::Section SWMMObjectTreeModel::sectionAtTopRow

(

int

topRow

)

const

Slice BM.0 — section discriminator for a top-level row.

Here is the caller graph for this function:

setData()

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

override

Here is the call graph for this function:

setLayer()

void SWMMObjectTreeModel::setLayer

(

SWMMModelLayer *

layer

)

Bind the model to a SWMM layer. Triggers beginResetModel / endResetModel and rebuilds the cached visible-category list. Pass nullptr to detach.

Here is the call graph for this function:

Here is the caller graph for this function:

supportedDropActions()

Qt::DropActions SWMMObjectTreeModel::supportedDropActions ( ) const

override

topRowForCategory()

int SWMMObjectTreeModel::topRowForCategory

(

SWMMModelLayer::Category

const

Top-level row for a given category, or -1 when that category contains no visible objects (empty categories are omitted).

Here is the caller graph for this function:

topRowForDataCategory()

int SWMMObjectTreeModel::topRowForDataCategory

(

SWMMModelLayer::DataCategory

c

)

const

Slice BM.0 — top-level row for a given data category, or -1 when empty / not currently shown.
