The Angle Measure plugin is a small tool which is used to measure the angular distance between two points on the sky. More...

Detailed Description

goes misty eyed* I recall measuring the size of the Cassini Division when I was a student. It was not the high academic glamor one might expect... It was cloudy... It was rainy... The observatory lab had some old scopes set up at one end, pointing at a photograph of Saturn at the other end of the lab. We measured. We calculated. We wished we were in Hawaii.

Note: Georg Zotti extended in 2014-09, enough to call it V4.0; Georg Zotti added properties in 2020-04, enough to call it V4.6

Modes

Equatorial Mode (original): mark start,end: distance/position angle in the sky, line rotates with sky, spherical angles influenced by refraction (numbers given on celestial sphere).

Horizontal Mode: mark start,end: distance/position angle in alt/azimuthal coordinates, line stays fixed in alt-az system. Angle may be different near to horizon because of refraction!

It is possible to link start and/or end to the sky. Distance/position angle still always in alt/azimuthal coordinates.

◆ configureGui()

virtual bool AngleMeasure::configureGui ( bool show = true )

virtual

This is to be used with plugins to display a configuration dialog from the plugin list window.

Parameters

show	if true, make the configuration GUI visible. If false, hide the config GUI if there is one.

Returns: true if the module has a configuration GUI, else false.

Reimplemented from StelModule.

◆ draw()

virtual void AngleMeasure::draw ( StelCore * core )

virtual

Parameters

core	the core to use for the drawing

Reimplemented from StelModule.

◆ getCallOrder()

virtual double AngleMeasure::getCallOrder ( StelModuleActionName actionName ) const

virtual

Parameters

actionName the name of the action for which we want the call order

Returns: the value defining the order. The closer to 0 the earlier the module's action will be called

Reimplemented from StelModule.

◆ handleKeys()

virtual void AngleMeasure::handleKeys ( class QKeyEvent * e )

virtual

Please note that most of the interactions will be done through the GUI module.

Parameters

e	the Key event

Returns: set the event as accepted if it was intercepted

Reimplemented from StelModule.

◆ handleMouseClicks()

virtual void AngleMeasure::handleMouseClicks ( class QMouseEvent * )

virtual

Please note that most of the interactions will be done through the GUI module.

Returns: set the event as accepted if it was intercepted

Reimplemented from StelModule.

◆ handleMouseMoves()

virtual bool AngleMeasure::handleMouseMoves	(	int	x,
		int	y,
		Qt::MouseButtons	b
	)

virtual

Please note that most of the interactions will be done through the GUI module.

Returns: true if the event was intercepted

Reimplemented from StelModule.

◆ init()

virtual void AngleMeasure::init ( )

virtual

If the initialization takes significant time, the progress should be displayed on the loading bar.

Implements StelModule.

◆ loadSettings()

void AngleMeasure::loadSettings ( )

Settings are kept in the "AngleMeasure" section in Stellarium's configuration file. If no such section exists, it will load default values.

See also: saveSettings(), restoreSettings()

◆ restoreDefaultSettings()

void AngleMeasure::restoreDefaultSettings ( )

Replace the plug-in's settings in Stellarium's configuration file with the default values and re-load them. Uses internally loadSettings() and saveSettings().

◆ update()

virtual void AngleMeasure::update ( double deltaTime )

virtual

Parameters

deltaTime the time increment in second since last call.

Reimplemented from StelModule.
