Constructor & Destructor Documentation

◆ LocalMeridianComponent()

LocalMeridianComponent::LocalMeridianComponent ( SkyComposite * parent)

Constructor Simply adds all of the coordinate grid circles (meridians and parallels) parent Pointer to the parent SkyComposite object.

Definition at line 19 of file localmeridiancomponent.cpp.

Member Function Documentation

◆ preDraw()

void LocalMeridianComponent::preDraw ( SkyPainter * skyp)

Gives the subclasses access to the top of the draw() method.

Typically used for setting the QPen, etc. in the QPainter being passed in. Defaults to setting a thin white pen.

Implements CoordinateGrid.

Definition at line 61 of file localmeridiancomponent.cpp.

◆ selected()

bool LocalMeridianComponent::selected ( )
true if component is to be drawn on the map.

Implements CoordinateGrid.

Definition at line 51 of file localmeridiancomponent.cpp.

◆ update()

void LocalMeridianComponent::update ( KSNumbers * )

Update the sky position(s) of this component.

This function usually just updates the Horizontal (Azimuth/Altitude) coordinates of its member object(s). However, the precession and nutation must also be recomputed periodically. num Pointer to the KSNumbers object
