wibox.container.rotate ([widget[, dir]])
Returns a new rotate container.

A rotate container rotates a given widget. Use the widget property to set the widget and direction property for the direction. The default direction is "north" which doesn't change anything.

Parameters:

  • widget widget The widget to display. (optional)
  • dir string The direction to rotate to. (optional)

Returns:

    table A new rotate container.

Object properties

widget widget
The widget to be rotated.

Type constraints:

direction string · 1 signal
The direction of this rotating container.

Valid values are:

  • north
  • east
  • south
  • north

Usage example

Type constraints:

Usage:

    local normal = create_arrow('Normal')
    local north  = wibox.container {
        create_arrow('North'),
        direction = 'north',
        widget    = wibox.container.rotate
    }
    local south  = wibox.container {
        create_arrow('South'),
        direction = 'south',
        widget    = wibox.container.rotate
    }
    local east  = wibox.container {
        create_arrow('East'),
        direction = 'east',
        widget    = wibox.container.rotate
    }
    local west  = wibox.container {

        widget    = wibox.container.rotate
    }

Emit signals:

  • property::direction When the direction value changes.
    • self wibox.container.rotate The object which changed (useful when connecting many object to the same callback).
    • new_value dir The new value affected to the property.
children table · Inherited from wibox.widget.base
Get or set the children elements.

Type constraints:

  • children table The children.
all_children table · Inherited from wibox.widget.base
Get all direct and indirect children widgets. This will scan all containers recursively to find widgets Warning: This method it prone to stack overflow if there is a loop in the widgets hierarchy. A hierarchy loop is when a widget, or any of its children, contain (directly or indirectly) itself.

Type constraints:

  • children table The children.
forced_height number or nil · Inherited from wibox.widget.base
Force a widget height.

Type constraints:

  • height number or nil The height (nil for automatic)
forced_width number or nil · Inherited from wibox.widget.base
Force a widget width.

Type constraints:

  • width number or nil The width (nil for automatic)
opacity number · Inherited from wibox.widget.base
The widget opacity (transparency).

Type constraints:

  • opacity number The opacity (between 0 and 1) (default 1)
visible boolean · Inherited from wibox.widget.base
The widget visibility.
buttons table · Inherited from wibox.widget.base
The widget buttons.

The table contains a list of awful.button objects.

Object methods

:reset ()
Reset this layout.

The widget will be removed and the rotation reset.

: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.

See also:

widget::redraw_needed · Inherited from wibox.widget.base
When the widget content changed. This signal is emitted when the content of the widget changes. The widget will be redrawn, it is not re-layouted. Put differently, it is assumed that :layout() and :fit() would still return the same results as before.
