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.

◆ slewFocus

void SkyMapLite::slewFocus ( )

Step the Focus point toward the Destination point.
