Member Function Documentation

void QY2BarGraph::addSegment (  const QString &  label = QString(), int  value = 0 )

Add one segment to the bar graph.

void QY2BarGraph::drawContents (  QPainter *   )  [protected, virtual]

Draw the graph bar contents. Inherited from QFrame.

bool QY2BarGraph::index_invalid (  int  i, const char *  function_name )  const [protected]

Sanity check for segment index. Returns true if invalid, false if OK.

const QString QY2BarGraph::label (  int  segmentNo  )  const

Return the label of segment no. segmentNo. Any occurence of "%d" etc. will not be expanded here but returned as passed to setLabel().

const QColor QY2BarGraph::segmentBackgroundColor (  int  segmentNo  )

Choose a background color suitable for segment no. segmentNo. Only a defined number of different colors are available. After that, previously used colors will be recycled.

const QColor QY2BarGraph::segmentForegroundColor (  int  segmentNo  )

Choose a foreground color suitable for segment no. segmentNo. that results in good contrast to the corresponding background color ( see abore )

int QY2BarGraph::segments (   )  const [inline]

Return the current number of segments.

void QY2BarGraph::setLabel (  int  segmentNo, const QString &  newLabel )

Set the label of segment no. segmentNo ( beginning with 0 ) to newLabel. May contain newlines or d for a reference to the current value.

void QY2BarGraph::setSegments (  int  segmentCount  )

Set the number of segments. Initialize all values and labels to zero values.

void QY2BarGraph::setValue (  int  segmentNo, int  newValue )

Set the value of segment no. segmentNo ( beginning with 0 ) to value newValue.

QSize QY2BarGraph::sizeHint (   )  const [virtual]

Return a suitable size for the widget.

int QY2BarGraph::sumValues (   )  const

Return the sum of all values,

int QY2BarGraph::value (  int  segmentNo  )  const

Return the current value of segment no. segmentNo.
