Class: QgsCurveEditorWidget¶
- class qgis.gui.QgsCurveEditorWidget¶
Bases:
PyQt5.QtWidgets.QWidget
A widget for manipulating
QgsCurveTransform
curves.New in version 3.0.
QgsCurveEditorWidget(parent: QWidget = None, curve:
QgsCurveTransform
= QgsCurveTransform()) Constructor for QgsCurveEditorWidget.Methods
Returns a curve representing the current curve from the widget.
- param event:
Returns the maximum expected value for the range of values shown in the histogram.
Returns the minimum expected value for the range of values shown in the histogram.
Sets the
curve
to show in the widget.Sets a
layer
andexpression
source for values to show in a histogram behind the curve.Sets the maximum expected value for the range of values shown in the histogram.
Sets the minimum expected value for the range of values shown in the histogram.
Signals
pyqtSignal(*types, name: str = ..., revision: int = ..., arguments: Sequence = ...) -> PYQT_SIGNAL
- actionEvent(self, QActionEvent)¶
- changeEvent(self, QEvent)¶
- 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
