Slider

The page is in the process of being translated.

A simple slider without a label. You can create a label using a Label object, for example. You need to specify a range that constrains the slider’s possible values.

The currently selected value is in the attribute value. Don’t change this value manually, but use the function set_close_to!(slider, value). This is necessary to ensure the value is actually present in the range attribute.

You can double-click the slider to reset it (approximately) to the value present in startvalue.

If you set the attribute snap = false, the slider will move continuously while dragging and only jump to the closest available value when releasing the mouse.
