Implements QgsSymbolV2.

Definition at line 831 of file qgssymbolv2.cpp.

QgsMarkerSymbolV2 * QgsMarkerSymbolV2::createSimple ( const QgsStringMap properties)
static

Create a marker symbol with one symbol layer: SimpleMarker with specified properties.

This is a convenience method for easier creation of marker symbols.

Definition at line 506 of file qgssymbolv2.cpp.

QgsDataDefined QgsMarkerSymbolV2::dataDefinedAngle ( ) const

Returns data defined angle for whole symbol (including all symbol layers).

Returns
data defined angle, or empty data defined if angle is not set at the marker level
Note
added in QGIS 2.9
See also
setDataDefinedAngle

Definition at line 606 of file qgssymbolv2.cpp.

QgsDataDefined QgsMarkerSymbolV2::dataDefinedSize ( ) const

Returns data defined size for whole symbol (including all symbol layers).

Returns
data defined size, or empty data defined if size is not set at the marker level
Note
added in QGIS 2.9

void QgsMarkerSymbolV2::setDataDefinedAngle ( const QgsDataDefined dd)

Set data defined angle for whole symbol (including all symbol layers).

Parameters
dddata defined angle
Note

dataDefinedAngle

Definition at line 580 of file qgssymbolv2.cpp.

void QgsMarkerSymbolV2::setDataDefinedSize ( const QgsDataDefined dd)

Set data defined size for whole symbol (including all symbol layers).

Parameters
dddata defined size

Definition at line 683 of file qgssymbolv2.cpp.

void QgsMarkerSymbolV2::setLineAngle ( double  lineAngle)

Sets the line angle modification for the symbol's angle.

This angle is added to the marker's rotation and data defined rotation before rendering the symbol, and is usually used for orienting symbols to match a line's angle.

Parameters
lineAngleAngle in degrees, valid values are between 0 and 360
