Class: QgsRangeSlider¶

A slider control with two interactive endpoints, for interactive selection of a range of values.

Added in version 3.18.

Base classes¶

QWidget
QObject
QPaintDevice

class qgis.gui.QgsRangeSlider[source]¶

Bases: QWidget

__init__(parent: QWidget | None = None)

Constructor for QgsRangeSlider, with the specified parent widget.

Parameters:: parent (Optional[QWidget] = None)

__init__(orientation: Qt.Orientation, parent: QWidget | None = None)

Constructor for QgsRangeSlider, with the specified parent widget.

The orientation parameter determines whether the slider is horizontal or vertical.

Parameters:

orientation (Qt.Orientation)
parent (Optional[QWidget] = None)

fixedRangeSize(self) → int[source]¶

Returns the slider’s fixed range size, or -1 if not set.

If a fixed range size is set then moving either the lower or upper slider will automatically move the other slider accordingly, in order to keep the selected range at the specified fixed size.

See also

setFixedRangeSize()

Added in version 3.38.

Return type:: int

signal fixedRangeSizeChanged[source]¶

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.

flippedDirection(self) → bool[source]¶

Returns True if the slider has its values flipped.

If this property is False (the default), the minimum and maximum will be shown in its classic position for the widget. If the value is True, the minimum and maximum appear at their opposite location.

setFlippedDirection()

Return type:: bool

lowerValue(self) → int[source]¶

Returns the lower value for the range selected in the widget.

upperValue()

setLowerValue()

Return type:: int

maximum(self) → int[source]¶

Returns the maximum value allowed by the widget.

setMaximum()

minimum()

Return type:: int

minimum(self) → int[source]¶

Returns the minimum value allowed by the widget.

setMinimum()

maximum()

Return type:: int

orientation(self) → Qt.Orientation[source]¶

Returns the orientation of the slider.

See also

setOrientation()

Return type:: Qt.Orientation

pageStep(self) → int[source]¶

Returns the page step value for the widget.

This corresponds to the larger increment or decrement applied when the user presses the page increment key (usually PageUp or PageDown).

setPageStep()

singleStep()

Return type:: int

signal rangeChanged[source]¶

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.

signal rangeLimitsChanged[source]¶

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.

setFixedRangeSize(self, size: int)[source]¶

Sets the slider’s fixed range size. Set to -1 if no fixed size is desired.

If a fixed range size is set then moving either the lower or upper slider will automatically move the other slider accordingly, in order to keep the selected range at the specified fixed size.

fixedRangeSize()

Added in version 3.38.

Parameters:: size (int)

setFlippedDirection(self, flipped: bool)[source]¶

Sets whether the slider has its values flipped.

If this property is False (the default), the minimum and maximum will be shown in its classic position for the widget. If the value is True, the minimum and maximum appear at their opposite location. (i.e. minimum at the bottom of a vertical slider, maximum at the top of a vertical slider).
