Member Function Documentation

boundingRect()

QRectF DdtGraphicalElementRefLine::boundingRect ( ) const

virtual

Function returning the bounding box of the graphics item

Returns

Rectangle with the bounding box

Reimplemented from DdtGraphicalElement.

DrawElement()

void DdtGraphicalElementRefLine::DrawElement ( QPainter *  painter )

virtual

Virtual function for rendering the graphical element

Implements DdtGraphicalElement.

End()

(

QGraphicsScene *

scene

)

Redraw the corner grabbers

Parameters

scene

Scene to add the grabbers

ReDrawLine()

void DdtGraphicalElementRefLine::ReDrawLine	(	const QPointF	start,
		const QPointF	end
	)

Redraw the line at new coordinates

Parameters

start	Start point
end	End point

ResetEventFilter()

void DdtGraphicalElementRefLine::ResetEventFilter
