示例1: TextSymbol
/**
* Creates a field schema that we'll later use as a labeling template for
* TrackNode instances.
*/
void
createFieldSchema( TrackNodeFieldSchema& schema )
{
// draw the track name above the icon:
TextSymbol* nameSymbol = new TextSymbol();
nameSymbol->pixelOffset()->set( 0, 2+ICON_SIZE/2 );
nameSymbol->alignment() = TextSymbol::ALIGN_CENTER_BOTTOM;
nameSymbol->halo()->color() = Color::Black;
nameSymbol->size() = nameSymbol->size()->eval() + 2.0f;
schema[FIELD_NAME] = TrackNodeField(nameSymbol, false); // false => static label (won't change after set)
// draw the track coordinates below the icon:
TextSymbol* posSymbol = new TextSymbol();
posSymbol->pixelOffset()->set( 0, -2-ICON_SIZE/2 );
posSymbol->alignment() = TextSymbol::ALIGN_CENTER_TOP;
posSymbol->fill()->color() = Color::Yellow;
posSymbol->size() = posSymbol->size()->eval() - 2.0f;
schema[FIELD_POSITION] = TrackNodeField(posSymbol, true); // true => may change at runtime
// draw some other field to the left:
TextSymbol* numberSymbol = new TextSymbol();
numberSymbol->pixelOffset()->set( -2-ICON_SIZE/2, 0 );
numberSymbol->alignment() = TextSymbol::ALIGN_RIGHT_CENTER;
schema[FIELD_NUMBER] = TrackNodeField(numberSymbol, false);
}示例2: createTrackSchema
void createTrackSchema(TrackNodeFieldSchema& schema)
{
// draw the track name above the icon:
TextSymbol* nameSymbol = new TextSymbol();
nameSymbol->pixelOffset()->set( 0, 2+TRACK_ICON_SIZE/2 );
nameSymbol->alignment() = TextSymbol::ALIGN_CENTER_BOTTOM;
nameSymbol->halo()->color() = Color::Black;
