Constructor & Destructor Documentation

te::qt::widgets::Info::Info	(	MapDisplay *	display,
		const QCursor &	cursor,
		const std::list< te::map::AbstractLayerPtr > &	layers,
		QObject *	parent = `0`
	)

It constructs a info tool associated with the given map display.

Parameters

display	The map display associated with the tool.
cursor	The tool cursor.
layers	The layer list that will be queried.
parent	The tool's parent.

Note: The tool will NOT take the ownership of the given pointers.

te::qt::widgets::Info::~Info ( )

Destructor.

Member Function Documentation

void te::qt::widgets::Info::drawGeometry ( te::gm::Geometry * g )

private

virtual bool te::qt::widgets::AbstractTool::eventFilter	(	QObject *	watched,
		QEvent *	e
	)

virtualinherited

Filters events if this object has been installed as an event filter for the watched object.

Parameters

watched	The watched object.
event	The last event sent to watched object.

Note: In your reimplementation of this function, if you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.; Here, the default implementation looks for QMouseEvents and call the pure virutal methods defined on AbstractTool class, e.g. mousePressEvent().

Reimplemented in te::qt::widgets::ZoomKeyboard, and te::qt::widgets::ZoomWheel.

void te::qt::widgets::Info::getGeometryInfo	(	QTreeWidgetItem *	layerItem,
		te::da::DataSet *	dataset,
		const std::string &	geomPropertyName,
		const te::gm::Envelope &	e,
		int	srid,
		bool	needRemap
	)

private

void te::qt::widgets::Info::getInfo	(	const te::map::AbstractLayerPtr &	layer,
		const te::gm::Envelope &	e
	)

private

void te::qt::widgets::Info::getRasterInfo	(	QTreeWidgetItem *	layerItem,
		te::rst::Raster *	raster,
		const te::gm::Envelope &	e,
		int	srid,
		bool	needRemap
	)

private

virtual bool te::qt::widgets::AbstractTool::mouseDoubleClickEvent ( QMouseEvent * e )

virtualinherited

This event handler can be reimplemented in a concrete tool class to receive mouse double click events for the watched object.

Parameters

e	The mouse event.

Returns: If you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.

Note: The AbstractTool will also receive mouse press and mouse release events in addition to the double click event. It is up to the developer to ensure that the application interprets these events correctly.

Reimplemented in te::edit::VertexTool, te::qt::widgets::Measure, te::edit::SplitPolygonTool, te::edit::CreatePolygonTool, te::edit::CreateLineTool, te::edit::CreatePointTool, te::qt::widgets::PolygonAcquire, te::edit::AggregateAreaTool, te::edit::SubtractAreaTool, and te::mnt::ProfileTools.

virtual bool te::qt::widgets::AbstractTool::mouseMoveEvent ( QMouseEvent * e )

virtualinherited

This event handler can be reimplemented in a concrete tool class to receive mouse move events for the watched object.

Parameters

e	The mouse event.

Returns: If you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.

Reimplemented in te::edit::VertexTool, te::qt::widgets::Measure, te::edit::SplitPolygonTool, te::qt::widgets::Selection, te::edit::CreatePolygonTool, te::edit::DeleteGeometryByAreaTool, te::edit::MoveGeometryTool, te::edit::CreateLineTool, te::qt::widgets::PolygonAcquire, te::qt::widgets::PanExtent, te::qt::widgets::ExtentAcquire, te::edit::AggregateAreaTool, te::qt::widgets::RubberBand, te::qt::widgets::CoordTracking, te::qt::widgets::Pan, te::qt::widgets::ZoomArea, te::qt::widgets::PanMiddleClick, te::edit::SubtractAreaTool, te::mnt::ProfileTools, and te::qt::plugins::mnt::ShowValuesTool.

virtual bool te::qt::widgets::AbstractTool::mousePressEvent ( QMouseEvent * e )

virtualinherited

This event handler can be reimplemented in a concrete tool class to receive mouse press events for the watched object.

Parameters

e	The mouse event.

Returns: If you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.

Reimplemented in te::edit::VertexTool, te::qt::widgets::Measure, te::edit::SplitPolygonTool, te::qt::widgets::Selection, te::edit::CreatePolygonTool, te::edit::DeleteGeometryByAreaTool, te::edit::MoveGeometryTool, te::edit::DeleteGeometryTool, te::edit::DeletePartTool, te::edit::CreateLineTool, te::edit::CreatePointTool, te::qt::widgets::PolygonAcquire, te::qt::widgets::PanExtent, te::qt::widgets::ExtentAcquire, te::edit::AggregateAreaTool, te::qt::widgets::RubberBand, te::qt::widgets::Pan, te::qt::widgets::ZoomClick, te::qt::widgets::ZoomArea, te::qt::widgets::PanMiddleClick, te::qt::widgets::ZoomLeftAndRightClick, te::edit::SubtractAreaTool, te::edit::EditInfoTool, and te::mnt::ProfileTools.

bool te::qt::widgets::Info::mouseReleaseEvent ( QMouseEvent * e )

virtual

This event handler can be reimplemented in a concrete tool class to receive mouse release events for the watched object.

Parameters

e	The mouse event.

Returns: If you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.

Reimplemented from te::qt::widgets::AbstractTool.

virtual void te::qt::widgets::AbstractTool::setCursor ( const QCursor & cursor )

virtualinherited

It sets the tool cursor.

Parameters

cursor The cursor that will be used during the tool operation.
