Detailed Description

A QAbstractItemModel subclass for showing symbol and color ramp entities contained within a QgsStyle database.

If you are creating a style model for the default application style (see QgsStyle::defaultStyle()), consider using the shared style model available at QgsApplication::defaultStyleModel() for performance instead.

Constructor & Destructor Documentation

◆ QgsStyleModel()

QgsStyleModel::QgsStyleModel ( QgsStyle style,
QObject *  parent = nullptr 
)
explicit

Constructor for QgsStyleModel, for the specified style and parent object.

The style object must exist for the lifetime of this model.

Definition at line 28 of file qgsstylemodel.cpp.

Member Function Documentation

◆ addDesiredIconSize()

void QgsStyleModel::addDesiredIconSize ( QSize  size)

Adds an additional icon size to generate for Qt::DecorationRole data.

This allows style icons to be generated at an icon size which corresponds exactly to the view's icon size in which this model is used.

Definition at line 482 of file qgsstylemodel.cpp.

int QgsStyleModel::columnCount ( const QModelIndex &  parent = QModelIndex()) const
override

Definition at line 477 of file qgsstylemodel.cpp.

◆ data()

QVariant QgsStyleModel::data ( const QModelIndex &  index,
int  role 
) const
override

Definition at line 73 of file qgsstylemodel.cpp.

◆ flags()

Qt::ItemFlags QgsStyleModel::flags ( const QModelIndex &  index) const
override

Definition at line 407 of file qgsstylemodel.cpp.

◆ headerData()

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

Definition at line 420 of file qgsstylemodel.cpp.

◆ index()

QModelIndex QgsStyleModel::index ( int  row,
int  column,
const QModelIndex &  parent = QModelIndex() 
) const
override

Definition at line 449 of file qgsstylemodel.cpp.

◆ parent()

QModelIndex QgsStyleModel::parent ( const QModelIndex &  index) const
override

Definition at line 462 of file qgsstylemodel.cpp.

◆ rowCount()

int QgsStyleModel::rowCount ( const QModelIndex &  parent = QModelIndex()) const
override

Definition at line 468 of file qgsstylemodel.cpp.

◆ setData()

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

Definition at line 343 of file qgsstylemodel.cpp.

◆ style()

QgsStyle* QgsStyleModel::style ( )
inline

Returns the style managed by the model.
