| 19 | \brief The Slider Widget
|
|---|
| 20 |
|
|---|
| 21 | QwtSlider is a slider widget which operates on an interval
|
|---|
| 22 | of type double. Its position is related to a scale showing
|
|---|
| 23 | the current value.
|
|---|
| 24 |
|
|---|
| 25 | The slider can be customized by having a through, a groove - or both.
