Member Function Documentation

boundingRect()

QRectF DdtGraphicalElementStatRectangle::boundingRect ( ) const

virtual

Function returning the bounding box of the graphics item

Returns

Rectangle with the bounding box

Reimplemented from DdtGraphicalElement.

DrawElement()

void DdtGraphicalElementStatRectangle::DrawElement ( QPainter *  painter )

virtual

Virtual function for rendering the graphical element

Implements DdtGraphicalElement.

End()

QPointF DdtGraphicalElementStatRectangle::End

(

)

const

Returns the end point of the rectangle

Returns

end point

LowerLeft()

(

QGraphicsScene *

scene

)

Method which can be called to redraw the corner grabbers of this rectangle

Parameters

scene

Scene to add the corners to

ReDrawRectangle()

void DdtGraphicalElementStatRectangle::ReDrawRectangle	(	const QPointF	p1,
		const QPointF	p2
	)

Redraw the rectangle at new coordinates

Parameters

start	Start point
end	End point

ResetEventFilter()

void DdtGraphicalElementStatRectangle::ResetEventFilter

(

)
