Detailed Description

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. The labels are painted very late, i.e. also sky object labels will be written over the landscape.

Member Function Documentation

int LabelMgr::deleteAllLabels ( void  )
slot
Returns
the number of labels deleted
void LabelMgr::deleteLabel ( int  id)
slot
Returns
true if the id existed and was deleted, else false
int LabelMgr::labelHorizon ( const QString &  text,
float  az,
float  alt,
bool  visible = true,
float  fontSize = 14,
const QString &  fontColor = "#999999",
bool  autoDelete = false,
int  autoDeleteTimeoutMs = 0 
)
slot

Can be used e.g. to show landscape features

Parameters
textthe text to display
azazimuth, degrees
altaltitude, degrees
visibleif true, the label starts displayed, else it starts hidden
fontSizesize of the font to use
fontColorHTML-like color spec, e.g. "#ffff00" for yellow
autoDeletethe label will be automatically deleted after it is displayed once
autoDeleteTimeoutMsif not zero, the label will be automatically deleted after autoDeleteTimeoutMs ms
int LabelMgr::labelObject ( const QString &  text,
const QString &  objectName,
bool  visible = true,
float  fontSize = 14,
const QString &  fontColor = "#999999",
const QString &  side = "E",
double  labelDistance = -1.0,
const QString &  style = "TextOnly",
bool  autoDelete = false,
int  autoDeleteTimeoutMs = 0 
)
slot
Parameters
textthe text to display
objectNamethe English name of the object to attach to
visibleif true, the label starts displayed, else it starts hidden
fontSizesize of the font to use
fontColorHTML-like color spec, e.g. "#ffff00" for yellow
sidewhere the label appears in relation to object:
  • "N" = above object on screen
  • "S" = below object on screen
  • "E" = to the right of the object on screen
  • "W" = to the left of the object on screen
  • "NE", "NW", "SE", "SW" work too.
Returns
a unique ID which can be used to refer to the label. returns -1 if the label could not be created (e.g. object not found)
Parameters
autoDeletethe label will be automatically deleted after it is displayed once
autoDeleteTimeoutMsif not zero, the label will be automatically deleted after autoDeleteTimeoutMs ms
