bool Updraft::Core::PickHandler::eventsCloseEnough	(	float	x1,
		float	y1,
		float	x2,
		float	y2
	)		[protected]

Says whether two mouse events are close enough to belong together.

Parameters:

x1	X-coordinate of the first event
y1	Y-coordinate of the first event
x2	X-coordinate of the second event
y2	Y-coordinate of the second event

Returns:

True if the events are close enough.

QVector< Pair > Updraft::Core::PickHandler::getIntersectedMapObjects	(	const double	x,
		const double	y,
		osgViewer::Viewer *	viewer
	)		[protected]

Get all MapObjectes associated with nodes intersected by a click.

Parameters:

x	The normalized X-coordinate of the mouse click
y	The normalized Y-coordinate of the mouse click
viewer	The viewer currently used to render the scene

Returns:

QVector of all map objects that were intersected by the click action with the given normalized coordinates.

bool Updraft::Core::PickHandler::handle	(	const osgGA::GUIEventAdapter &	ea,
		osgGA::GUIActionAdapter &	aa
	)

Handles the osg gui event.

It gets all of the intersected map objects and then, according to the event type, either a left click or right click is raised.

Parameters:

ea	The osg event adapter for the event that is being handled.
aa	The osg action adapter for the current event. This is not used in thecurrent implementation.

Returns:

true If the event was accepted and handled.

void Updraft::Core::PickHandler::raiseLeftClick

(

QVector< Pair >

mapObjects

)

[protected]

Method that calls the click handlers for all interested plugins for all intersected map objects.

Parameters:

mapObjects

The vector of intersected map objects.

void Updraft::Core::PickHandler::raiseRightClick

(

QVector< Pair >

mapObjects

)

[protected]

Requests the context menu actions from all plugins for all intersected map objects.

The context menu is then executed.

Parameters:

mapObjects

The vector of intersected map objects.
