class	YBarGraphMultiUpdate

Detailed Description

A graph showing partitioning of a whole. The whole is divided into YBarGraphSegment each of which has a relative size, a text color, a background color, and a label.

Constructor & Destructor Documentation

◆ YBarGraph()

YBarGraph::YBarGraph ( YWidget * parent )

protected

Constructor.

◆ ~YBarGraph()

YBarGraph::~YBarGraph ( )

virtual

Destructor.

Member Function Documentation

◆ addSegment()

void YBarGraph::addSegment ( const YBarGraphSegment & segment )

Add one segment.

If the segment's background and text colors are not explicitly specified, the YBarGraph widget will assign them from a list of (at least 5 different) color sets.

When adding multiple segments, use a YBarGraphMultiUpdate object for improved performance to hold back display updates until all segments are added.

◆ deleteAllSegments()

void YBarGraph::deleteAllSegments ( )

Delete all segments.

◆ doUpdate()

virtual void YBarGraph::doUpdate ( )

protectedpure virtual

Perform a display update after any change to any of the segments.

Derived classes are required to implement this.

◆ getProperty()

YPropertyValue YBarGraph::getProperty ( const std::string & propertyName )

virtual

Get a property. Reimplemented from YWidget.

This method may throw YUIPropertyExceptions.

Reimplemented from YWidget.

◆ propertySet()

const YPropertySet & YBarGraph::propertySet ( )

virtual

Return this class's property set. This also initializes the property upon the first call.

Reimplemented from YWidget.

◆ segment()

const YBarGraphSegment & YBarGraph::segment ( int segmentIndex ) const

Return the segment with the specified index (from 0 on).

This will throw an exception if there are not this many segments.

◆ segments()

int YBarGraph::segments ( ) const

Return the current number of segments.

◆ setLabel()

void YBarGraph::setLabel	(	int	segmentIndex,
		const std::string &	newLabel )

Set the label of the segment with the specified index (from 0 on). Use %1 as a placeholder for the current value.

This will throw an exception if there are not this many segments.

Note: Use a YBarGraphMultiUpdate object for improved performance when doing multiple changes at the same time.

◆ setProperty()

bool YBarGraph::setProperty	(	const std::string &	propertyName,
		const YPropertyValue &	val )

virtual

Set a property. Reimplemented from YWidget.

This function may throw YUIPropertyExceptions.

This function returns 'true' if the value was successfully set and 'false' if that value requires special handling (not in error cases: those are covered by exceptions).

Reimplemented from YWidget.

◆ setSegmentColor()

void YBarGraph::setSegmentColor	(	int	segmentIndex,
		const YColor &	color )

Set the background color of the segment with the specified index (from 0 on).

This will throw an exception if there are not this many segments or if the color is undefined.

◆ setTextColor()

void YBarGraph::setTextColor	(	int	segmentIndex,
		const YColor &	color )

Set the text color of the segment with the specified index (from 0 on).

This will throw an exception if there are not this many segments or if the color is undefined.

◆ setValue()

void YBarGraph::setValue	(	int	segmentIndex,
		int	newValue )

Set the value of the segment with the specifie index (from 0 on).

This will throw an exception if there are not this many segments.

Note: Use a YBarGraphMultiUpdate object for improved performance when doing multiple changes at the same time.

◆ widgetClass()

virtual const char * YBarGraph::widgetClass ( ) const

inlinevirtual

Return a descriptive name of this widget class for logging, debugging etc.

Reimplemented from YWidget.

The documentation for this class was generated from the following files:
