Member Function Documentation

void QSDrvQt::beginPolyline (  const QSPt2f &    pos )  [virtual]

Starts to draw a polyline. Implements QSCanvasDrv. Reimplemented in QSDrvHitTest.

void QSDrvQt::clearCanvas (  const QSGFill &    f, const QSPt2f &    pos, const QSPt2f &    size )  [virtual]

Clear the canvas. Reimplemented from QSDrv. Reimplemented in QSDrvHitTest.

virtual QSDrvQt* QSDrvQt::copy (    )  [virtual]

Returns a copy of this object. Implements QSDrv. Reimplemented in QSDrvHitTest.

QPainter* QSDrvQt::copyPainter (  const QPainter *    painter )  [static]

Creates and returns a copy of painter.

void QSDrvQt::copySettingsFrom (  const QSDrvQt *    drv )

Copies painter, dpi settings.

QSGFill QSDrvQt::currentFill (    )  [virtual]

This function should return the current fill. Reimplemented from QSCanvasDrv.

QSGFont QSDrvQt::currentFont (    )  [virtual]

This function should return the current font. Reimplemented from QSCanvasDrv.

QSGLine QSDrvQt::currentLine (    )  [virtual]

This function should return the current line. Reimplemented from QSCanvasDrv.

QSPt2f QSDrvQt::currPolylinePos (    )  [inline, virtual]

Returns the current pen position. Reimplemented from QSCanvasDrv. Reimplemented in QSDrvHitTest.

bool QSDrvQt::deletePainter (    )  const [inline]

Returns 'delete' painter setting

void QSDrvQt::drawEllipse (  const QSPt2f &    p1, const QSPt2f &    p2 )  [virtual]

Draws a circle. Implements QSCanvasDrv. Reimplemented in QSDrvHitTest.

void QSDrvQt::drawLine (  const QSPt2f &    one, const QSPt2f &    two )  [virtual]

Draw a line. Implements QSCanvasDrv. Reimplemented in QSDrvHitTest.

void QSDrvQt::drawPixmap (  const QSPt2f &    pos, PixmapBuffer *    data )  [virtual]

Draw a pixmap. Notice that the pixmap buffer will be always the last requested one.'getPixmapBuffer' / 'drawPixmap' pair is always called together. Reimplemented from QSCanvasDrv. Reimplemented in QSDrvHitTest.

void QSDrvQt::drawPoly (  const QSPt2f    pts[], int    npoints, const bool    edges[] = NULL, int    edgeAutoColor = 0 )  [virtual]

Draw a polygon defined by 'npoints' points in 'pts'. Can change the current line ( if edgeAuto color != 0 ) Implements QSCanvasDrv. Reimplemented in QSDrvHitTest.

void QSDrvQt::drawPolylineTo (  const QSPt2f &    pos )  [virtual]

Draw the next line segment. Wach out for setLine() call during drawPolyline2() Implements QSCanvasDrv. Reimplemented in QSDrvHitTest.

void QSDrvQt::drawRect (  const QSPt2f &    p1, const QSPt2f &    p2 )  [virtual]

Draw a rectangle. Implements QSCanvasDrv. Reimplemented in QSDrvHitTest.

void QSDrvQt::drawRText (  const QSPt2f &    pos, int    angle, const QString &    text, int    align = AlignLeft|AlignBottom )  [virtual]

Draw a rotated text. This must be reimplemented. Implements QSCanvasDrv. Reimplemented in QSDrvHitTest.

void QSDrvQt::drawText (  const QSPt2f &    pos, const QString &    text, int    align = AlignLeft|AlignBottom )  [virtual]

Draw a text. Implements QSCanvasDrv. Reimplemented in QSDrvHitTest.

void QSDrvQt::endPolyline (    )  [virtual]

Ends polyline. Reimplemented from QSCanvasDrv. Reimplemented in QSDrvHitTest.

void QSDrvQt::getPixmapBuffer (  PixmapBuffer *    buff, int    pwidth, int    pheight )  [virtual]

This method is always called before QSDrv::drawPixmap. The struct 'PixmapBuffer' must be filled with correct values. Pixmap width is requested to be equal to 'pwidth', pixmap height must be lower or equal to pheight ( see field 'lines' in 'PixmapBuffer' ). Reimplemented from QSCanvasDrv. Reimplemented in QSDrvHitTest.

void QSDrvQt::getRTextBoundingPoly (  QSPt2f    outPts[4], const QSPt2f &    pos, int    angle, const QString &    text, int    align = AlignLeft|AlignBottom )  [virtual]

Return size of a rotated text. This must be reimplemented. Implements QSCanvasDrv.

QPainter* QSDrvQt::painter (    )  const [inline]

Returns painter

virtual void QSDrvQt::setDC (  QPainter *    p, double    dpi = 72.0, bool    deletePainter = false )  [virtual]

Sets a painter. If deletePainter is true, painter is deleted in destructor. This driver calls neither p->start(), nor p->stop() Reimplemented in QSDrvOpenGL.

void QSDrvQt::setFill (  const QSGFill &    f )  [virtual]

Set the current fill . Implements QSCanvasDrv. Reimplemented in QSDrvHitTest.

void QSDrvQt::setFont (  const QSGFont &    f )  [virtual]

Set the current font. Implements QSCanvasDrv.

void QSDrvQt::setLine (  const QSGLine &    l )  [virtual]

Set the current line style. Implements QSCanvasDrv. Reimplemented in QSDrvHitTest.

void QSDrvQt::startDrawing (    )  [virtual]

Reimplemented from QSDrv::startDraw . Reimplemented from QSDrv. Reimplemented in QSDrvOpenGL.

void QSDrvQt::stopDrawing (    )  [virtual]

Reimplemented from QSDrv::stopDraw . Doesn,t call paint->end(). Reimplemented from QSDrv. Reimplemented in QSDrvOpenGL.

QSPt2f QSDrvQt::textSize (  const QString &    text )  [virtual]

Return the size of the text that will be printed by the corresponding QSDrv::drawText function. Implements QSCanvasDrv.

QBrush QSDrvQt::toQBrush (  const QSGFill &    f )  [static]

Converts 'QSGFill' to 'QBrush' .

QColor QSDrvQt::toQColor (  const QSGColor &    c )  [static]

Converts 'QSGColor' to 'QColor' .

QFont QSDrvQt::toQFont (  const QSGFont &    f, double    dpi = 72.0 )  [static]

Converts 'QSGFont' to 'QFont' .

QPen QSDrvQt::toQPen (  const QSGLine &    p )  [static]

Converts 'QSGLine' to 'QPen' .
