Destructor

Member Function Documentation

boundingRect()

QRectF DdtGraphicalElementRefLine::boundingRect ( ) const

overridevirtual

Function returning the bounding box of the graphics item

Returns

Rectangle with the bounding box

Reimplemented from DdtGraphicalElement.

DrawElement()

void DdtGraphicalElementRefLine::DrawElement ( QPainter * painter )

overridevirtual

Virtual function for rendering the graphical element

Implements DdtGraphicalElement.

End()

QPointF DdtGraphicalElementRefLine::End

(

)

const

Returns the end point of the line

Returns

end point

ReDrawLine()

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

Redraw the line at new coordinates

Parameters

start	Start point
end	End point

RedrawPoints()

void DdtGraphicalElementRefLine::RedrawPoints

(

QGraphicsScene *

scene

)

Redraw the point grabbers

Parameters

scene

Scene to add the grabbers

ResetEventFilter()

void DdtGraphicalElementRefLine::ResetEventFilter

(

)

Reset the event filter flag; used after item had been removed from the scene, so that the event filter is re-installed in the corner grabbers

Start()

(

)

const

Returns the starting point of the line

Returns

starting point

type()

int DdtGraphicalElementRefLine::type ( ) const

override

Check type of graphics item

Returns

type
