Detailed Description

QgsSettingsTreeNode is a tree node for the settings tree to help organizing and introspecting the tree.

It is either a root node, a normal node or a named list (to store a group of settings under a dynamic named key). to automatically register a settings entry on its creation when a parent is provided.

inline

Returns the children settings.

Definition at line 115 of file qgssettingstreenode.h.

childSetting()

const QgsSettingsEntryBase * QgsSettingsTreeNode::childSetting

(

const QString &

key

)

const

Returns the existing child settings if it exists at the given key.

Definition at line 99 of file qgssettingstreenode.cpp.

completeKey()

QString QgsSettingsTreeNode::completeKey ( ) const

inline

Returns the complete key of the node (including its parents)

key

)

Creates a normal tree node It will return the existing child node if it exists at the given key.

Exceptions

QgsSettingsException

if a setting exists with the same key

Definition at line 51 of file qgssettingstreenode.cpp.

createNamedListNode()

QgsSettingsTreeNamedListNode * QgsSettingsTreeNode::createNamedListNode	(	const QString &	key,
		const Qgis::SettingsTreeNodeOptions &	options = Qgis::SettingsTreeNodeOptions()
	)

This is useful to register groups of settings for several named items (for instance credentials for several named services)

Definition at line 66 of file qgssettingstreenode.cpp.

createRootNode()

QgsSettingsTreeNode * QgsSettingsTreeNode::createRootNode ( )

static

Creates a tree root node.

Note

This is not available in Python bindings. Use QgsSettingsTree.createPluginTreeNode instead.

key()

QString QgsSettingsTreeNode::key ( ) const

inline

Returns the key of the node (without its parents)

Definition at line 124 of file qgssettingstreenode.h.

QgsSettingsTreeNode * QgsSettingsTreeNode::parent ( ) const

inline

Returns the parent of the node or nullptr if it does not exists.

Definition at line 121 of file qgssettingstreenode.h.

registerChildNode()

void QgsSettingsTreeNode::registerChildNode ( QgsSettingsTreeNode *  node )

protected

Registers a child nodes.

Definition at line 122 of file qgssettingstreenode.cpp.

registerChildSetting()

void QgsSettingsTreeNode::registerChildSetting	(	const QgsSettingsEntryBase *	setting,
		const QString &	key
	)

Registers a child setting.

Parameters

setting	the setting to register
key	the key of the setting (not the complete key from its parents)

Note

Ownership of the setting is transferred

The registration is automatically done when calling the setting's constructor with the parent argument signature

Exceptions
