bool readBoolEntry(const QString &scope, const QString &key, bool def=false, bool *ok=nullptr) const
Whether to use also label candidates that are partially outside of the map view.
Whether to only draw the label rect and not the actual label text (used for unit tests) ...
int readNumEntry(const QString &scope, const QString &key, int def=0, bool *ok=nullptr) const
Whether to render labels as text or outlines.
void readSettingsFromProject(QgsProject *project)
Read configuration of the labeling engine from a project.
void clear()
Return the configuration to the defaults.
Whether to draw all labels even if there would be collisions.
bool writeEntry(const QString &scope, const QString &key, bool value)
Write a boolean entry to the project file.
Reads and writes project states.
Whether to draw rectangles of generated candidates (good for debugging)
QgsLabelingEngineSettings()
void writeSettingsToProject(QgsProject *project)
Write configuration of the labeling engine to a project.
