Detailed Description

Map layer group used by plugins.

This class encapsulates handling of the map layer group. It provides methods for creating and deleting layers and automatically adding to/deleting from the GUI.

Constructor & Destructor Documentation

Updraft::Core::MapLayerGroup::MapLayerGroup ( const QString & title ) [explicit]

Creates new map layer group.

For creating new instances use CoreInterface or for creating sub groups use MapLayerGroup::createMapLayerGroup.

Parameters:

title Displayed name of the widget.

Updraft::Core::MapLayerGroup::MapLayerGroup ( QTreeWidgetItem * item ) [explicit]

Create a new map layer group based on already existing tree item.

Updraft::Core::MapLayerGroup::~MapLayerGroup ( )

Destroys MapLayerGroup Removes coresponding tree widget from GUI.

Member Function Documentation

void Updraft::Core::MapLayerGroup::addToScene ( MapLayerGroup * group ) [private, virtual]

Add the map layer to the osg group of the map layer group.

Implements Updraft::MapLayerInterface.

MapLayerInterface * Updraft::Core::MapLayerGroup::createMapLayer	(	osg::Node *	layer,
		const QString &	title,
		int	pos = `-1`
	)		`[virtual]`

Create a single map layer containing the node and add it as a child of this group.

Returns:: The new layer.

Implements Updraft::MapLayerGroupInterface.

MapLayerGroupInterface * Updraft::Core::MapLayerGroup::createMapLayerGroup	(	const QString &	title,
		int	pos = `-1`
	)		`[virtual]`

Create a single empty map layer group and add it as a child of this.

Returns:: The new group.

Implements Updraft::MapLayerGroupInterface.

MapLayerInterface * Updraft::Core::MapLayerGroup::createMapLayerNoInsert	(	osg::Node *	layer,
		const QString &	title,
		int	pos = `-1`
	)		`[private, virtual]`

Add map layer without adding it to scene.

Implements Updraft::MapLayerGroupInterface.

osg::Group * Updraft::Core::MapLayerGroup::getNodeGroup ( ) [virtual]

Returns the osg group associated with this map layer group.

Implements Updraft::MapLayerGroupInterface.

osgEarth::Util::ObjectPlacer * Updraft::Core::MapLayerGroup::getObjectPlacer ( ) [virtual]

Returns the placer associated with the mapNode.

Implements Updraft::MapLayerGroupInterface.

void Updraft::Core::MapLayerGroup::inserted ( Core::MapLayerGroup * parent ) [private, virtual]

Sets the parent map layer group of this map layer.

Parameters:

parent The new parent group of this map layer.

Reimplemented from Updraft::Core::MapLayer.

void Updraft::Core::MapLayerGroup::insertMapLayer	(	MapLayerInterface *	layer,
		int	pos = `-1`
	)		`[virtual]`

Insert the map layer as a child of this group.

Implements Updraft::MapLayerGroupInterface.

bool Updraft::Core::MapLayerGroup::isVisible ( ) [virtual]

Implements Updraft::MapLayerInterface.

void Updraft::Core::MapLayerGroup::removeFromScene ( MapLayerGroup * group ) [private, virtual]

Remove the layer from the osg group of the map layer group.

Implements Updraft::MapLayerInterface.

void Updraft::Core::MapLayerGroup::removeMapLayer ( MapLayerInterface * layer ) [virtual]

Remove the map layer from this group, but don't delete it.

Ownership of the layer is transfered to caller of this method.

Implements Updraft::MapLayerGroupInterface.

bool Updraft::Core::MapLayerGroup::restoreState ( const QByteArray & state ) [virtual]

Restore the previsously saved state.

See also:: saveState()

Reimplemented from Updraft::Core::MapLayer.

QByteArray Updraft::Core::MapLayerGroup::saveState ( ) [virtual]

Save the state (check state and expanded state) of this layer (and possibly all children).

Note:: Format of the save is following: 1) For each child: a) Save child's id b) Save the child's data as QByteArray 3) Null QByteArray as a separator 4) Save this as MapLayer

Reimplemented from Updraft::Core::MapLayer.

void Updraft::Core::MapLayerGroup::setDisabled ( bool disabled ) [private, virtual]

Disables or enables the map layer.

Parameters:

disabled Whether the layer should be disabled.

Reimplemented from Updraft::Core::MapLayer.

void Updraft::Core::MapLayerGroup::setVisibility ( bool value ) [virtual]

Displays/hides the map layer.

Parameters:

value The new state of visibility.

Implements Updraft::Core::MapLayer.
