Member Function Documentation

virtual void QtView::draw (  QPainter &   )  [virtual]

Re-Implements the inherited function from QCanvasPoygonalItem. First calls base class to draw the contents. If selected, then also draws the border and sends update message to m_inspector.

virtual void QtView::drawShape (  QPainter &   )  [virtual]

Overrides pure virtual function of QCanvasPolygonalItem. Reimplemented from QCanvasRectangle.

virtual void QtView::endPlot (   )  [virtual]

Finalizes the plot view by unlocking the QApplication. Implements ViewBase.

virtual void QtView::fillPickedPoint (  double  , double  , std::vector< double > &  )  const [virtual]

virtual void QtView::initPlot (  double   )  [virtual]

Initializes a view before drawing. The view should check it size. The parameter aspect, if greater than 0.0, sets the aspect ratio of the view, i.e. the ratio of the width to the height. Implements ViewBase.

virtual void QtView::setDrawRect (  float  , float  , float  , float  )  [virtual]

Sets the drawing rectangle in the paint device space. Implements ViewBase.

void QtView::setDrawRect (  const QRect &   )

Sets the drawing rectangle in the paint device space.

virtual void QtView::setPageWidth (  int   )  [virtual]

Set the page width. It is used for setting the dimensions of the draw rectangle

virtual void QtView::setShowCrossHairs (  bool   )  [virtual]

Sets display status of cross-hairs. Sets the display of cross-hairs at the previous defined position on if flag is true, otherwise does not display the cross-hairs. See also: setCrossX and setCrossY.

int QtView::toViewX (  double   )  const

Converts the data space coordinate X to the view space coordinate X.

int QtView::toViewY (  double   )  const

Converts the data space coordinate Y to the view space coordinate Y.

virtual void QtView::update (  const Observable *   )  [virtual]

Responds to Obvervable update message. If display is not null, responds to Obvervable update message by informing the QCanvas that its rectangluar has changed. Implements ViewBase.
