Module: wibox.widget.progressbar

A progressbar widget.

Components

Common usage examples

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

Usage example

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%",
        valign = "center",
        align  = "center",
        widget = wibox.widget.textbox,
    },
    layout = wibox.layout.stack
}

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

Usage example

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.

To have a gradient between 2 colors when the bar reaches a threshold, use the gears.color gradients:

Usage example

wibox.widget {
    color = {
        type  = "linear",
        from  = { 0  , 0 },
        to    = { 100, 0 },
        stops = {
            { 0  , "#0000ff" },
            { 0.8, "#0000ff" },
            { 1  , "#ff0000" }
        }
    },
    max_value     = 1,
    value         = 1,
    forced_height = 20,
    forced_width  = 100,
    paddings      = 1,
    border_width  = 1,
    border_color  = beautiful.border_color,
    widget        = wibox.widget.progressbar,
}

The same goes for multiple solid colors:

Usage example

for _, value in ipairs { 0.3, 0.5, 0.7, 1 } do
    wibox.widget {
        color = {
            type  = "linear",
            from  = { 0  , 0 },
            to    = { 100, 0 },
            stops = {
                { 0  , "#00ff00" },
                { 0.5, "#00ff00" },
                { 0.5, "#ffff00" },
                { 0.7, "#ffff00" },
                { 0.7, "#ffaa00" },
                { 0.8, "#ffaa00" },
                { 0.8, "#ff0000" },
                { 1  , "#ff0000" }
            }
        },
        max_value     = 1,
        value         = value,
        forced_height = 20,
        forced_width  = 100,
        paddings      = 1,
        border_width  = 1,
        border_color  = beautiful.border_color,
        widget        = wibox.widget.progressbar,
    }
end

Usage example

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,
}

    }

    -- With a gradient.
    wibox.widget {
        color = {
            type  = "linear",
            from  = { 0 , 0 },
            to    = { 65, 0 },
            stops = {
                { 0   , "#0000ff" },
                { 0.75, "#0000ff" },
                { 1   , "#ff0000" }

Emit signals:

  • property::ticks_size When the ticks_size value changes.
    • self wibox.widget.progressbar The object which changed (useful when connecting many object to the same callback).
    • new_value ticks_size The new value affected to the property.
max_value number · 1 signal
The maximum value the progressbar should handle.

By default, the value is 1. So the content of value is a percentage.

Usage example

    • new_value max_value The new value affected to the property.
margins (table or number or nil) · 1 signal · 1 theme variable
The progressbar margins.

The margins are around the progressbar. If you want to add space between the bar and the border, use paddings.

Usage example

wibox.widget {
    {
        margins = {
            top    = 4,
            bottom = 2,
            right  = 10,
            left   = 5
        },
        value        = 0.33,
        border_width = 2,
        border_color = "#00ff00",
        background   = "#0000ff",
        widget       = wibox.widget.progressbar,
    },
    forced_width = 75, --DOC_hIDE
    bg     = "#ff0000",
    widget = wibox.container.background
}

Note that if the clip is disabled, this allows the background to be smaller than the bar.

It is also possible to specify a single number instead of a border for each direction;

Usage example

Type constraints:

  • margins A table for each side or a number
    • top number (default 0)
    • bottom number (default 0)
    • left number (default 0)
    • right number (default 0)

Usage:

    for _, margin in ipairs { 0, 2, 4, 6 } do
    wibox.widget {
        value   = 0.33,
        margins = margin,
        widget  = wibox.widget.progressbar,
    }

paddings (table or number or nil) · 1 signal · 1 theme variable
The progressbar padding.

This is the space between the inner bar and the progressbar outer border.

Note that if the clip is disabled, this allows the bar to be taller than the background.

Usage example

wibox.widget {
    paddings = {
        top    = 4,
        bottom = 2,
        right  = 10,

Deprecated functions

wibox.widget.progressbar.set_vertical [deprecated]
Set the progressbar to draw vertically.

This doesn't do anything anymore, use a wibox.container.rotate widget.

Parameters:

  • vertical boolean
wibox.widget.progressbar.set_height [deprecated]
Set the progressbar height.

This method is deprecated. Use a wibox.container.constraint widget or forced_height.

Parameters:

  • height number The height to set.
wibox.widget.progressbar.set_width [deprecated]
Set the progressbar width.

This method is deprecated. Use a wibox.container.constraint widget or forced_width.

Parameters:

  • width number The width to set.

Object methods

:add_button (button) · Inherited from wibox.widget.base
Add a new awful.button to this widget.

Parameters:

  • button awful.button The button to add.
:emit_signal_recursive (signal_name, ...) · Inherited from wibox.widget.base

Emit a signal and ensure all parent widgets in the hierarchies also forward the signal.

This is useful to track signals when there is a dynamic set of containers and layouts wrapping the widget.

Note that this function has some flaws:

  1. The signal is only forwarded once the widget tree has been built. This happens after all currently scheduled functions have been executed. Therefore, it will not start to work right away.
  2. In case the widget is present multiple times in a single widget tree, this function will also forward the signal multiple times (once per upward tree path).
  3. If the widget is removed from the widget tree, the signal is still forwarded for some time, similar to the first case.

Parameters:

  • signal_name string
  • ... Other arguments
:index (widget[, recursive[, ...]]) -> (number, widget, table) · Inherited from wibox.widget.base
Get the index of a widget.

Parameters:

  • widget widget The widget to look for.
  • recursive boolean Recursively check accross the sub-widgets hierarchy. (optional)
  • ... widget Additional widgets to add at the end of the sub-widgets hierarchy "path". (optional)

Returns:

  1. number The widget index.
  2. widget The parent widget.
  3. table The hierarchy path between "self" and "widget".
:connect_signal (name, func) · Inherited from gears.object

Connect to a signal.

Usage example output:

In slot [obj]   nil nil nil
In slot [obj]   foo bar 42

Parameters:

  • name string The name of the signal.
  • func function The callback to call when the signal is emitted.

Usage:

    local o = gears.object{}
-- Function can be attached to signals
local function slot(obj, a, b, c)
    print("In slot", obj, a, b, c)
end
o:connect_signal("my_signal", slot)
-- Emitting can be done without arguments. In that case, the object will be
-- implicitly added as an argument.
o:emit_signal "my_signal"
-- It is also possible to add as many random arguments are required.
o:emit_signal("my_signal", "foo", "bar", 42)
-- Finally, to allow the object to be garbage collected (the memory freed), it
-- is necessary to disconnect the signal or use weak_connect_signal
o:disconnect_signal("my_signal", slot)
-- This time, the slot wont be called as it is no longer connected.
o:emit_signal "my_signal"
:weak_connect_signal (name, func) · Inherited from gears.object
Connect to a signal weakly.

This allows the callback function to be garbage collected and automatically disconnects the signal when that happens. Warning: Only use this function if you really, really, really know what you are doing.

Parameters:

  • name string The name of the signal.
  • func function The callback to call when the signal is emitted.
:disconnect_signal (name, func) · Inherited from gears.object
Disonnect from a signal.

Parameters:

  • name string The name of the signal.
  • func function The callback that should be disconnected.
:emit_signal (name, ...) · Inherited from gears.object
Emit a signal.

Parameters:

  • name string The name of the signal
  • ... Extra arguments for the callback functions. Each connected function receives the object as first argument and then any extra arguments that are given to emit_signal()

Signals

widget::layout_changed · Inherited from wibox.widget.base
When the layout (size) change. This signal is emitted when the previous results of :layout() and :fit() are no longer valid. Unless this signal is emitted, :layout() and :fit() must return the same result when called with the same arguments.
