Detailed Description

strategy pattern. A class that configures and updates a Tango plot according to the properties of Tango attributes (minimum and maximum values)

The update implementation configures the plot with the default Y lower and upper bounds taken from the attribute properties (if the source is a Tango attribute).

After the configuration phase, QuPlotBase::update is called in order to draw the graph.

Constructor & Destructor Documentation

◆ QuTPlotUpdateStrategy()

QuTPlotUpdateStrategy::QuTPlotUpdateStrategy ( bool auto_configure = true )

The class constructor.

Parameters

auto_configure	true the plot uses Tango attribute properties to configure lower and upper bounds
auto_configure	false no auto configuration is performed. Upper and lower bounds must be set manually or the plot scales must be put in autoscale mode

◆ ~QuTPlotUpdateStrategy()

QuTPlotUpdateStrategy::~QuTPlotUpdateStrategy ( )

virtual

the class destructor

Member Function Documentation

◆ update()

void QuTPlotUpdateStrategy::update	(	const CuData &	da,
		QWidget *	widget
	)

implementation of the QuWidgetUpdateStrategyI::update method mainly aimed at setting up the plot default lower and upper y scale bounds

Parameters

da	data from the attribute (command)
widget	the QuPlotBase that will be configured (the target of the stragegy pattern).

if the CuData bundle contains the key "type" with value "property", then the plot is configured taking minimum and maximum values from the Tango attribute properties. Otherwise, QuPlotBase::update is called.
