## Class: QDial
|
|
|
|
> Create and control dial slider widgets.
|
|
|
|
**This class is a JS wrapper around Qt's [QDial class](https://doc.qt.io/qt-5/qdial.html)**
|
|
|
|
A `QDial` provides ability to add and manipulate native dial slider widgets.
|
|
|
|
**QDial inherits from [QAbstractSlider](api/QAbstractSlider.md)**
|
|
|
|
### Example
|
|
|
|
```javascript
|
|
const { QDial } = require("@nodegui/nodegui");
|
|
|
|
const dial = new QDial();
|
|
```
|
|
|
|
### `new QDial(parent?)`
|
|
|
|
- `parent` NodeWidget (_optional_). Any widget inheriting from NodeWidget can be passed as a parent. This will make this widget, the child of the parent widget.
|
|
|
|
### Static Methods
|
|
|
|
QDial can access all the static methods defined in [NodeWidget](api/NodeWidget.md)
|
|
|
|
### Instance Properties
|
|
|
|
QDial can access all the instance properties defined in [NodeWidget](api/NodeWidget.md)
|

QDial can access all the instance methods defined in [NodeWidget](api/NodeWidget.md). Additionally it also has the following instance methods:
|
|
|
|
#### `dial.setNotchesVisible(visible)`
|
|
|
|
Sets the visibility of notches drawn around the dial. It calls the native method [QDial: setNotchesVisible](https://doc.qt.io/qt-5/qdial.html#notchTarget-prop).
|
|
|
|
- `visible` boolean - Set the value as current notch visibility.
|
|
|
|
#### `dial.setWrapping(on)`
|
|
|
|
Sets the ability to wrap arrow around the dial instead of limiting it to upper part of the dial. It calls the native method [QDial: setWrapping](https://doc.qt.io/qt-5/qdial.html#wrapping-prop).
|
|
|
|
- `on` boolean - Set the value as current wrapping setting.
|
|
|
|
#### `dial.setNotchTarget(target)`
|
|
|
|
Sets the number of pixels between dial notches. It calls the native method [QDial: setNotchTarget](https://doc.qt.io/qt-5/qdial.html#notchTarget-prop).
|
|
|
|
- `target` number - Specifies number of pixels between notches.
|
|
|
|
#### `dial.notchTarget()`
|
|
|
|
Returns the current number of pixels between dial notches. It calls the native method [QDial: notchTarget](https://doc.qt.io/qt-5/qdial.html#notchTarget-prop).
|
|
|
|
#### `dial.notchesVisible()`
|
|
|
|
Returns the visibility status (Boolean) of dial notches. It calls the native method [QDial: notchesVisible](https://doc.qt.io/qt-5/qdial.html#notchesVisible-prop).
|
|
|
|
#### `dial.notchesVisible()`
|
|
|
|
Returns the visibility status (Boolean) of dial notches. It calls the native method [QDial: notchesVisible](https://doc.qt.io/qt-5/qdial.html#notchesVisible-prop).
|
|
|
|
#### `dial.wrapping()`
|
|
