Constructor & Destructor Documentation

◆ QgsRangeSlider() [1/2]

QgsRangeSlider::QgsRangeSlider ( QWidget *  parent = nullptr)

Constructor for QgsRangeSlider, with the specified parent widget.

Definition at line 21 of file qgsrangeslider.cpp.

◆ QgsRangeSlider() [2/2]

QgsRangeSlider::QgsRangeSlider ( Qt::Orientation  orientation,

Member Function Documentation

◆ event

bool QgsRangeSlider::event ( QEvent *  event)
overrideslot

Definition at line 186 of file qgsrangeslider.cpp.

◆ fixedRangeSize()

int QgsRangeSlider::fixedRangeSize ( ) const

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.

setFixedRangeSize()
Since
QGIS 3.38

Definition at line 347 of file qgsrangeslider.cpp.

◆ fixedRangeSizeChanged

void QgsRangeSlider::fixedRangeSizeChanged ( int  size)
signal

Emitted when the widget's fixed range size is changed.

See also
fixedRangeSize()
setFixedRangeSize()

QGIS 3.38

◆ flippedDirection()

bool QgsRangeSlider::flippedDirection ( ) const

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.
