Member Function Documentation

QSPt2f QSRectf::bottomRight (    )  const

Returns coordinates of bottom-left corner ( the corner furthermost from (0,0) )

bool QSRectf::contains (  const QSPt2f &    pos )  const

Returns if point is inside the rectangle

QSRectf QSRectf::normalize (    )  const

Normalizes rectangle ( makes size > 0 )

QSRectf QSRectf::normalizeHeight (    )  const

Normalizes height ( makes it > 0 )

QSRectf QSRectf::normalizeWidth (    )  const

Normalizes width ( makes it > 0 )

QSPt2f QSRectf::p1 (    )  const [inline]

Returns 'pos'.

QSPt2f QSRectf::p2 (    )  const [inline]

Returns 'pos'+'size'

QRect QSRectf::rect (    )  const

Rounds coordinates and converst rectangle to QRect.

void QSRectf::setBottomRight (  const QSPt2f &    p )

Sets bottom-right ( with maximum coordinates ) corner of this rectangle to 'p'. Never changes topLeft corner..

void QSRectf::setP1 (  const QSPt2f &    p )  [inline]

P1 is point at 'pos'. This function changes 'pos' and 'size' of this rectangle but never changes P2

void QSRectf::setP2 (  const QSPt2f &    p )  [inline]

P2 is the point at 'pos'+'size'. This function changes 'size' of this rectangle, but never changes 'size'.

void QSRectf::setTopLeft (  const QSPt2f &    p )

Sets top-left ( with minimal coordinates ) corner of this rectange. Doesnt change bottom-right corner.

QSPt2f QSRectf::topLeft (    )  const

Returns coordinates of the top-left corner ( the corner closest to (0,0) ).

void QSRectf::unite (  const QSRectf &    rect )

Unites the rectangle with other rectangle.
