Detailed Description

DartBoard implementation that uses Taurus to get the Target and Current positions to from two different models, each one of them an array of two doubles radians.

model -> Current position target_model -> Target Position

Constructor & Destructor Documentation

◆ init()

def taurusdartboard.TaurusDartBoard.__init__	(		self,
			parent = `None`,
		*	args,
		**	kwargs
	)

Initializer for TaurusDartBoard.

Member Function Documentation

◆ handleEvent()

def taurusdartboard.TaurusDartBoard.handleEvent	(		self,
		Attribute	evt_src,
		TaurusEventType	evt_type,
			evt_val
	)

Overrides TaurusBaseComponent.handleEvent.

Since we have now two models, each one generates a subscription to its own Attribute. Every time a new event is generated by the Attribute, this method is called.

Normally, only one evt_src (the Attribute name) would call this method, but since we have two Attributes (one for model, another for target_model) we have to distinguish between evt_src to update the adequete properties in the widget.

Let's remember that the QeDartBoard widget has for properties of interest:

- targetAlt
- targetAz
- currentAlt
- currentAz

So when the evt_src == target_model, then we update

- targetAlt

- targetAz

and when evt_src == model, then we update

- currentAlt

- currentAz

Parameters

[in]	evt_src	Name of the Attribute that generates the event
[in]	evt_type	Type of Event according to taurus.core.taurusbasetypes.TaurusEventType
[in]	evt_val	Value of the event

◆ isReadOnly()

bool taurusdartboard.TaurusDartBoard.isReadOnly ( self )

Overrides TaurusBaseComponent.isReadOnly.

Indicates that the widget is a read only widget.

◆ setTargetModel()

def taurusdartboard.TaurusDartBoard.setTargetModel	(	self,
		new_model
	)

Setter for target_model property.

This should point to a Taurus Model that is an array of two double radians.

Sets the model used to get the values for the Target Altitude and Azimuth properties on the QeDartBoard.

It also creates the Attribute for that model.

Parameters

[in] new_model String that contains a URI for the Taurus Model.
