Allows for creation of custom labels on objects or coordinates.
Because this class is intended for use in scripting (although other uses are also fine), all label types and so on are specified by QString descriptions. TODO: when QT4.5 is out, change implementation to use QGraphicsTextItem. (QT4.5 should allow for opacity changes for fades, but it is not currently implemented.
int LabelMgr::deleteAllLabels | ( | void | ) | [slot] |
Delete all labels.
bool LabelMgr::deleteLabel | ( | int | id | ) | [slot] |
Delete a label by the ID which was returned from addLabel...

Create a label which is attached to a StelObject.
text | the text to display | |
objectName | the English name of the object to attach to | |
visible | if true, the label starts displayed, else it starts hidden | |
fontSize | size of the font to use | |
fontColor | HTML-like color spec, e.g. "#ffff00" for yellow | |
side | where the label appears in relation to object:

Create a label at fixed screen coordinates.
text | the text to display | |
x | the horizontal position on the screen, in pixels, from the left of the screen | |
y | the vertical position on the screen, in pixels, from the top of the screen | |
visible | if true, the label starts displayed, else it starts hidden | |
fontSize | size of the font to use | |
fontColor | HTML-like color spec, e.g. "#ffff00" for yellow |
