QgsRangeSlider::QgsRangeSlider | ( | QWidget * | parent = nullptr | ) |
Constructor for QgsRangeSlider, with the specified parent widget.
Definition at line 21 of file qgsrangeslider.cpp.
QgsRangeSlider::QgsRangeSlider | ( | Qt::Orientation | orientation, |

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.
Definition at line 347 of file qgsrangeslider.cpp.
|
signal |
Emitted when the widget's fixed range size is changed.
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.

void QgsRangeSlider::setFixedRangeSize | ( | int | size | ) |
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.
Definition at line 352 of file qgsrangeslider.cpp.
void QgsRangeSlider::setFlippedDirection | ( | bool | flipped | ) |
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).
