Class: QgsConditionalLayerStyles¶
- class qgis.core.QgsConditionalLayerStyles¶
Bases:
PyQt5.QtCore.QObject
The
QgsConditionalLayerStyles
class holds conditional style information for a layer. This includes field styles and full row styles.QgsConditionalLayerStyles(parent: QObject = None) Constructor for
QgsConditionalLayerStyles
, with the specifiedparent
object.Methods
Returns the conditional styles set for the field with matching
fieldName
.Reads the condition styles state from a DOM node.
Returns a list of row styles associated with the layer.
Returns
True
if at least one rule needs geometry.Set the conditional
styles
for a field, with the specifiedfieldName
.Sets the conditional
styles
that apply to full rows of data in the attribute table.Writes the condition styles state to a DOM node.
Signals
pyqtSignal(*types, name: str = ..., revision: int = ..., arguments: Sequence = ...) -> PYQT_SIGNAL
- changed¶
pyqtSignal(*types, name: str = …, revision: int = …, arguments: Sequence = …) -> PYQT_SIGNAL
types is normally a sequence of individual types. Each type is either a type object or a string that is the name of a C++ type. Alternatively each type could itself be a sequence of types each describing a different overloaded signal. name is the optional C++ name of the signal. If it is not specified then the name of the class attribute that is bound to the signal is used. revision is the optional revision of the signal that is exported to QML. If it is not specified then 0 is used. arguments is the optional sequence of the names of the signal’s arguments.
- Parameters:
name (str = ...) –
revision (int = ...) –
arguments (Sequence = ...) –
- Return type:
PYQT_SIGNAL
