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.

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.
