Constructor & Destructor Documentation

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 25 of file qgsstylemodel.cpp.

Member Function Documentation

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.
