# Class `wibox.widget.progressbar`

A progressbar widget.

To add text on top of the progressbar, a wibox.layout.stack can be used:

    wibox.widget {
        {
            max_value     = 1,
            value         = 0.5,
            forced_height = 20,
            forced_width  = 100,
            paddings      = 1,
            border_width  = 1,
            border_color  = beautiful.border_color,
            widget        = wibox.widget.progressbar,
        },
        {
            text   = '50%',
            widget = wibox.widget.textbox,
        },
        layout = wibox.layout.stack
    }

To display the progressbar vertically, use a wibox.container.rotate widget:

    wibox.widget {
        {
            max_value     = 1,
            value         = 0.33,
            widget        = wibox.widget.progressbar,
        },
        forced_height = 100,
        forced_width  = 20,
        direction     = 'east',
        layout        = wibox.container.rotate,
    }

By default, this widget will take all the available size. To prevent this, a wibox.container.constraint widget or the forced_width/forced_height properties have to be used.

### Usage:

    wibox.widget {
        max_value     = 1,
        value         = 0.33,
        forced_height = 20,
        forced_width  = 100,
        shape         = gears.shape.rounded_bar,
        border_width  = 2,
        border_color  = beautiful.border_color,
        widget        = wibox.widget.progressbar,
    }
