Detailed Description

template<typename T>
class QgsSettingsEntryEnumFlag< T >

A template class for enum and flag settings entry.

Note

This template class has a dedicated handling in sipify.py

Constructor & Destructor Documentation

QgsSettingsEntryEnumFlag() [1/2]

template<typename T >

QgsSettingsEntryEnumFlag< T >::QgsSettingsEntryEnumFlag ( const QString &  name, QgsSettingsTreeNode *  parent, T  defaultValue, const QString &  description = QString(), Qgis::SettingsOptions  options = Qgis::SettingsOptions()  )

inline

Constructor for QgsSettingsEntryEnumFlagBase.

Parameters

name	specifies the name of the setting.
parent	specifies the parent in the tree of settings.
defaultValue	specifies the default value for the settings entry.
description	specifies a description for the settings entry.
options	specifies the options for the settings entry.

Note

The enum needs to be declared with Q_ENUM, and flags with Q_FLAG (not Q_FLAGS).

for Python bindings, a custom implementation is achieved in Python directly

inline

Constructor for QgsSettingsEntryEnumFlagBase.

Parameters

key	specifies the final part of the setting key.
section	specifies the section.
defaultValue	specifies the default value for the settings entry.
description	specifies a description for the settings entry.
options	specifies the options for the settings entry.

Note

The enum needs to be declared with Q_ENUM, and flags with Q_FLAG (not Q_FLAGS).
