Detailed Description

This is the main item that displays all SkyItems.

After its instantiation it is reparanted to an object with objectName SkyMapLiteWrapper in main.qml. To display SkyItems they are reparanted to instance of SkyMapLite.

SkyMapLite handles most user interaction events (both mouse and keyboard).

Item for displaying sky objects; also handles user interaction events.

Member Function Documentation

◆ addFOVSymbol()

void SkyMapLite::addFOVSymbol ( const QString & FOVName,
bool initialState = false )

adds FOV symbol to m_FOVSymbols

Parameters
FOVNamename of a FOV symbol
initialStatedefines whether the state is initial

Definition at line 919 of file skymaplite.cpp.

◆ clickedObject()

SkyObject * SkyMapLite::clickedObject ( ) const
inline

Retrieve the object nearest to a mouse click event.

If the user clicks on the sky map, a pointer to the nearest SkyObject is stored in the private member ClickedObject. This function returns the ClickedObject pointer, or nullptr if there is no CLickedObject.

Returns
a pointer to the object nearest to a user mouse click.

Definition at line 234 of file skymaplite.h.

◆ clickedPoint()

SkyPoint * SkyMapLite::clickedPoint ( )
inline

Retrieve the ClickedPoint position.

When the user clicks on a point in the sky map, the sky coordinates of the mouse cursor are stored in the private member ClickedPoint. This function retrieves a pointer to ClickedPoint.

Returns
a pointer to ClickedPoint, the sky coordinates where the user clicked.

Definition at line 217 of file skymaplite.h.

◆ createInstance()

SkyMapLite * SkyMapLite::createInstance ( )
static

Creates instance of SkyMapLite (delete the old one if any)

Definition at line 215 of file skymaplite.cpp.

◆ deleteLimit()

double SkyMapLite::deleteLimit ( )
static

return limit of hides for the node to delete it

Definition at line 199 of file skymaplite.cpp.

◆ deleteSkyNode()

void SkyMapLite::deleteSkyNode ( SkyNode * skyNode)

skyNode will be deleted on the next call to updatePaintNode (currently used only in StarNode(struct in StarBlock))

Definition at line 205 of file skymaplite.cpp.

◆ destination()

SkyPoint * SkyMapLite::destination ( )
inline

retrieve the Destination position.

The Destination is the point on the sky to which the focus will be moved.

Returns
a pointer to the destination point of the sky map

Definition at line 135 of file skymaplite.h.

◆ destinationChanged

void SkyMapLite::destinationChanged ( )
signal

Emitted by setDestination(), and connected to slewFocus().

Whenever the Destination point is changed, slewFocus() will iteratively step the Focus toward Destination until it is reached.

See also
SkyMap::setDestination()
SkyMap::slewFocus()

◆ focus()

SkyPoint * SkyMapLite::focus ( )
inline

Retrieve the Focus point; the position on the sky at the center of the skymap.

Returns
a pointer to the central focus point of the sky map

Definition at line 125 of file skymaplite.h.

◆ focusObject()

SkyObject * SkyMapLite::focusObject ( ) const
inline

Retrieve the object which is centered in the sky map.

If the user centers the sky map on an object (by double-clicking or using the Find Object dialog), a pointer to the "focused" object is stored in the private member FocusObject. This function returns a pointer to the FocusObject, or nullptr if there is not FocusObject.

Returns
a pointer to the object at the center of the sky map.

Definition at line 252 of file skymaplite.h.

◆ focusPoint()

SkyPoint * SkyMapLite::focusPoint ( )
inline

retrieve the FocusPoint position.

The FocusPoint stores the position on the sky that is to be focused next. This is not exactly the same as the Destination point, because when the Destination is set, it will begin slewing immediately.

Returns
a pointer to the sky point which is to be focused next.

Definition at line 149 of file skymaplite.h.

◆ forceUpdate

void SkyMapLite::forceUpdate ( )
slot

Recalculates the positions of objects in the sky, and then repaints the sky map.

Definition at line 639 of file skymaplite.cpp.

◆ forceUpdateNow

void SkyMapLite::forceUpdateNow ( )
inlineslot

Left for compatibility reasons.

See also
forceUpdate()

Definition at line 466 of file skymaplite.h.

◆ getAutomaticMode()

bool SkyMapLite::getAutomaticMode ( ) const
inline

True if automatic mode is on (SkyMapLite is controlled by smartphones accelerometer magnetometer)

Definition at line 438 of file skymaplite.h.

◆ getCachedTexture()

QSGTexture * SkyMapLite::getCachedTexture ( int size,
char spType )

returns cached texture from textureCache.

Use outside of scene graph rendering thread (e.g. not during call to updatePaintNode) is prohibited!

Parameters
sizesize of the star
spTypespectral class
Returns
cached QSGTexture from textureCache

Definition at line 210 of file skymaplite.cpp.

inline

getter for clickedPointLite

Definition at line 393 of file skymaplite.h.

◆ getFOVSymbols()

Q_INVOKABLE QStringList SkyMapLite::getFOVSymbols ( )
inline

this QList should be used as a model in QML to switch on/off FOV symbols

Definition at line 382 of file skymaplite.h.

This function does several different things depending on the state of the program:

  • If we are defining a ZoomBox, update the ZoomBox rectangle, redraw the screen, and return.
  • If dragging the mouse in the map, update focus such that RA, Dec under the mouse cursor remains constant.
