Constructor & Destructor Documentation

DtDragDropHandler::DtDragDropHandler ( )

Default Constructor.

virtual DtDragDropHandler::~DtDragDropHandler ( ) [virtual]

Destructor.

Member Function Documentation

virtual bool DtDragDropHandler::isValidForDrag	(	DtTMMapArea *	map,
		DtModelKey &	key
	)		`[virtual]`

Override to return true/false to determine if the selected object is valid for dragging.

The map is the map area that is scheduled for the drag operation to being in

Reimplemented in DtTerrainDragDropHandler, and DtFormationDragDropHandler.

virtual DtDragObject* DtDragDropHandler::createDragObject	(	DtTMMapArea *	activeMap,
		QString &	dragging
	)		`[virtual]`

Drag/Drop code Creates an object that will be used as part of the drag/drop operation to keep track of what is being dragged.

virtual void DtDragDropHandler::dragMove	(	DtTMMapArea *	area,
		DtModelData *	data,
		const DtPoint &	delta
	)		`[virtual]`

Moves the item by the supplied amount.

static DtEventHandler* DtDragDropHandler::create	(	DtEventController *	owner,
		void *	usr
	)		`[static]`

Static creator.

Reimplemented in DtTerrainDragDropHandler.

virtual bool DtDragDropHandler::mouseEvent	(	DtTMMapArea *	area,
		QMouseEvent *	evnt,
		const DtPoint &	pnt
	)		`[virtual, slot]`

Reimplemented from DtEventHandler.

virtual bool DtDragDropHandler::dropSymbols	(	DtTMMapArea *	area,
		QDropEvent *	e
	)		`[protected, virtual, slot]`

Called when dropping symbols from either the right mouse context menu or from the left button.

virtual bool DtDragDropHandler::dropEvent	(	DtTMMapArea *	area,
		QDropEvent *	evnt
	)		`[virtual]`

Reimplemented from DtEventHandler.

virtual bool DtDragDropHandler::dragMoveEvent	(	DtTMMapArea *	area,
		QDragMoveEvent *	evnt
	)		`[virtual]`

Reimplemented from DtEventHandler.

virtual bool DtDragDropHandler::dragEnterEvent	(	DtTMMapArea *	area,
		QDragEnterEvent *	evnt
	)		`[virtual]`

Reimplemented from DtEventHandler.

virtual bool DtDragDropHandler::dragLeaveEvent	(	DtTMMapArea *	area,
		QDragLeaveEvent *	evnt
	)		`[virtual]`

Reimplemented from DtEventHandler.

virtual bool DtDragDropHandler::canDrag ( DtTMMapArea * area ) const [protected, virtual]

Return true if this handler can start a drag.

Reimplemented in DtTerrainDragDropHandler.

virtual void DtDragDropHandler::endDrag	(	DtTMMapArea *	area,
		int	timerMsec
	)		`[protected, virtual]`

Called to remove drag symbols.

virtual bool DtDragDropHandler::getDropLocationData	(	DtTMMapArea *	area,
		const QPoint &	dropPoint,
		QString &	idStr,
		QVector< DtPoint > &	pnts,
		double	heightChange
	)		`[protected, virtual]`

Called when an item is dropped, this routine will allow for returning of new point data based upon the drop.

If no new point data is given, return false. The pnts list must contain new location data. The idStr is the id of the symbol that can be retrieved by calling getSymbol from the view driver or the model data by calling .find from the model data dictionary. Currently, this routine will see if the dropped item is of type intervisibility, and, if it is, massage the data

virtual DtDragData* DtDragDropHandler::dragDataForArea ( DtTMMapArea * area ) [protected, virtual]

Creates (or returns) a drag data object for the specified area.

virtual void DtDragDropHandler::tick ( ) [protected, virtual]

Reimplemented from DtEventHandler.

virtual void DtDragDropHandler::dropSymbol	(	DtTMMapArea *	area,
		const QPoint &	dropPoint,
		DtModelData *	symData,
		double	heightChange = `0.`
	)		`[protected, virtual]`

Drop the specified symbol into the map area.

Reimplemented in DtFormationDragDropHandler.

virtual int DtDragDropHandler::timeout ( ) const [protected, virtual]

Returns how long the temp symbols should stay on map before removing to show modified symbols.

virtual bool DtDragDropHandler::dragAboutToStart ( DtTMMapArea * ) [protected, virtual]

Called right before a drag is about to start. Return false to abort drag. Calls dragStart() in map area.

virtual void DtDragDropHandler::modifyPoint	(	const DtModelData &	data,
		DtPoint &	pnt
	)		`[protected, virtual]`

Override to modify the point before adding to model data.

virtual bool DtDragDropHandler::dropSymbols	(	DtTMMapArea *	area,
		const QPoint &	dropPoint,
		const QString &	idStr,
		double	heightChange = `0.`
	)		`[protected, virtual]`
