	)

protectedvirtual

Reimplemented from DtEventHandler.

virtual bool DtMapAreaSelectionHandler::isMovementKey ( int ) const

protectedvirtual

Returns true if the key is used for nudge movement.

virtual void DtMapAreaSelectionHandler::moveModelData	(	DtTMMapArea *	,
		DtModelData *	data,
		int	key
	)

protectedvirtual

Given the movement key, nudges the object in the appropriate direction by the pixels specified.

	)		const

protectedvirtual

Returns the point that is to be used as the basis for the z (height) change, if needed.

virtual bool DtMapAreaSelectionHandler::connecting ( DtTMMapArea * )

protectedvirtual

Hook up to selection change signals to do some processing. Default is no-op.

Reimplemented from DtEventHandler.

virtual bool DtMapAreaSelectionHandler::disconnecting ( DtTMMapArea * area )

protectedvirtual

Called when a map is being disconnect from an event handler.

Reimplemented from DtEventHandler.

virtual bool DtMapAreaSelectionHandler::isSelectedPointMove	(	DtTMMapArea *	,
		DtModelData *
	)		const

protectedvirtual

Returns true if the model data in question represents a line symbol that has a point selected.

If so, call routine to adjust just that selected point

virtual bool DtMapAreaSelectionHandler::isSelectedCircleMove	(	DtTMMapArea *	,
		DtModelData *
	)		const

protectedvirtual

Returns true if the object is a circle.

virtual void DtMapAreaSelectionHandler::moveSelectedPoint	(	DtTMMapArea *	,
		DtModelData *	,
		const DtPoint &	delta
	)

protectedvirtual

This routine will get a handle to the vertex editor handler and ask it to do the point movement.

This is done so that code will not need to be duplicated here

virtual void DtMapAreaSelectionHandler::circleMove	(	DtTMMapArea *	,
		DtModelData *	,
		const DtPoint &	delta
	)

protectedvirtual

This routine will get a handle to the circle resizing handler to move either the origin or the edge of the circle.

virtual void DtMapAreaSelectionHandler::dragMove	(	DtTMMapArea *	,
		DtModelData *	,
		const DtPoint &	delta
	)

protectedvirtual

Calls down to the drag/drop handler to move the selected symbol.

void DtMapAreaSelectionHandler::setXMovement ( double i )

inline

Amount to move in x, y, z direction.

For Z direction, this will mean meters change. For x, y the change is a percentage of the left/right or back/front size of the local extent. This means the more you are zoomed in, the smaller the move increment. X, Y default to 1 percent, Z defalts to 1 meter
