Return type: bool

isSignalConnected(self, QMetaMethod) → bool¶

isVisibleInZRange(self, range: QgsDoubleRange) → bool¶

Returns True if the layer should be visible and rendered for the specified z range.

Parameters: range (QgsDoubleRange) –
Return type: bool

readXml(self, element: QDomElement, context: QgsReadWriteContext) → bool¶
