Detailed Description

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

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

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.

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
showif 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.

virtual void AngleMeasure::draw ( StelCore core)
virtual
Parameters
corethe core to use for the drawing

Reimplemented from StelModule.

virtual double AngleMeasure::getCallOrder ( StelModuleActionName  actionName) const
virtual
Parameters
actionNamethe 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.

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

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

Parameters
ethe Key event
Returns
set the event as accepted if it was intercepted

Reimplemented from StelModule.

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.

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.

virtual void AngleMeasure::init ( )
virtual

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

Implements StelModule.

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()
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().

virtual void AngleMeasure::update ( double  deltaTime)
virtual
Parameters
deltaTimethe time increment in second since last call.

Implements StelModule.
