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 58 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.

setData()

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

override

Definition at line 461 of file qgsstylemodel.cpp.

setIconGenerator()

void QgsStyleModel::setIconGenerator ( QgsAbstractStyleEntityIconGenerator *  generator )

static

Sets the icon generator to use for deferred style entity icon generation.

Currently this is used for 3D symbol icons only.
