Knob

The QKnob component is used to take a number input from the user through mouse/touch panning. It is based on QCircularProgress and inherits all its properties and behavior.

Installation

// quasar.conf.js

return {
  framework: {
    // NOT needed if using auto-import feature:
    components: [
      'QKnob'
    ]
  }
}

Usage

By default, QKnob inherits current text color (as arc progress color and inner label color) and current font size (as component size). For customization, you can use the size and color related props.

Show value

In the example below, show-value property also enables the default slot, so you can fill it with custom content, like even a QAvatar or a QTooltip. The font-size prop refers to the inner label font size.

Native form submit

When dealing with a native form which has an action and a method (eg. when using Quasar with ASP.NET controllers), you need to specify the name property on QKnob, otherwise formData will not contain it (if it should):
