Member Function Documentation

QCanvasEllipse::QCanvasEllipse ( QCanvas * canvas )

Constructs a 32x32 ellipse, centered at (0,0) on canvas.

QCanvasEllipse::QCanvasEllipse ( int width, int height, QCanvas * canvas )

Constructs a width by height pixel ellipse, centered at (0,0) on canvas.

QCanvasEllipse::QCanvasEllipse ( int width, int height, int startangle, int angle, QCanvas * canvas )

Constructs a width by height pixel ellipse, centered at (0,0) on canvas, starting at angle startangle, extending for angle angle. startangle and angle are in 1/16 degrees.

QCanvasEllipse::~QCanvasEllipse ()

Destructs the ellipse.

int QCanvasEllipse::angleLength () const

Returns the length angle in 1/16 degrees. Initially this will be 360*16 - ie. a solid ellipse.

See also setAngles() and angleStart().

int QCanvasEllipse::angleStart () const

Returns the start angle in 1/16 degrees. Initially this will be 0.

See also setAngles() and angleLength().

QPointArray QCanvasEllipse::areaPoints () const [virtual]

Reimplemented for internal reasons; the API is not affected.

Reimplemented from QCanvasPolygonalItem.

bool QCanvasEllipse::collidesWith ( const QCanvasItem * i ) const [virtual]

Reimplemented for internal reasons; the API is not affected.

Reimplemented from QCanvasItem.

void QCanvasEllipse::drawShape ( QPainter & p ) [virtual protected]

Draws the ellipse, centered at x(), y().

Note that QCanvasPolygon does not support an outline (pen is always NoPen).

Reimplemented from QCanvasPolygonalItem.

int QCanvasEllipse::height () const

Returns the height of the ellipse.

int QCanvasEllipse::rtti () const [virtual]

Returns 6.

See also QCanvasItem::rtti().

Reimplemented from QCanvasItem.

void QCanvasEllipse::setAngles ( int start, int length )

Sets the angles for the ellipse to start at start and continue for length units. Each unit is 1/16 of a degree. By default the ellipse will start at 0 and have length 360*16 - ie. a solid ellipse.

See also angleStart() and angleLength().

void QCanvasEllipse::setSize ( int width, int height )

Sets the width and height of the ellipse.

int QCanvasEllipse::width () const

Returns the width of the ellipse.
