Member Function Documentation

boundingRect()

QRectF DdtGraphicalElementStatRectangle::boundingRect ( ) const

overridevirtual

Function returning the bounding box of the graphics item

Returns

Rectangle with the bounding box

Reimplemented from DdtGraphicalElement.

DrawElement()

void DdtGraphicalElementStatRectangle::DrawElement ( QPainter * painter )

overridevirtual

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()

(

)

const

Returns the lower left coordinates of the rectangle

Returns

lower left point

RedrawCorners()

void DdtGraphicalElementStatRectangle::RedrawCorners

(

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

p1	Start point
p2	End point

ResetEventFilter()

void DdtGraphicalElementStatRectangle::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

(

)

const

Returns the starting point of the rectangle

Returns

starting point

type()

int DdtGraphicalElementStatRectangle::type ( ) const

override

Check type of graphics item

Returns

type
