Detailed Description

Represent settings entry and provides methods for reading and writing settings values.

Different subclasses are provided for different settings types with metainformations to validate set values and provide more accurate settings description for the gui.

◆ QgsSettingsEntryBase()

QgsSettingsEntryBase::QgsSettingsEntryBase ( const QString &  key,

const QString &  description = QString(),
Qgis::SettingsOptions  options = Qgis::SettingsOptions() 
)
inline

Constructor for QgsSettingsEntryBase.

The key argument specifies the key of the settings. The section argument specifies the section. The defaultValue argument specifies the default value for the settings entry. The description argument specifies a description for the settings entry. The options argument specifies the options for the settings entry.
