Module: `wibox.widget.imagebox`

A widget to display image.

The wibox.widget.imagebox is part of the Awesome WM’s wiboxes system (see 03-declarative-layout.md).

This widget displays an image. The image can be a file, a cairo image surface, or an rsvg handle object (see the image property).

Use a wibox.widget.imagebox

Usage example

local my_imagebox = wibox.widget.imagebox(beautiful.awesome_icon, false)

Alternatively, you can declare the imagebox widget using the declarative pattern (Both codes are strictly equivalent):

local my_imagebox = wibox.widget {
    image  = beautiful.awesome_icon,
    resize = false,
    widget = wibox.widget.imagebox
}

Constructors

wibox.widget.imagebox ([image[, resize_allowed[, clip_shape]]])

Returns a new wibox.widget.imagebox instance.

This is the constructor of wibox.widget.imagebox. It creates a new instance of imagebox widget.

Alternatively, the declarative layout syntax can handle wibox.widget.imagebox instanciation.

The image can be a file, a cairo image surface, or an rsvg handle object (see the image property).

Any additional arguments will be passed to the clip shape function.

Parameters:

image image The image to display (may be nil). (optional)
resize_allowed boolean If false, the image will be clipped, else it will be resized to fit into the available space. (optional)
clip_shape function A gears.shape compatible function. (optional)

Returns:

wibox.widget.imagebox

Object properties

image (image) · 1 signal

The image rendered by the imagebox.

It can can be any of the following:

A string : Interpreted as the path to an image file,
A cairo image surface : Directly used as is,
An rsvg handle object : Directly used as is,
nil : Unset the image.

Type constraints:

image image The image to render.

Emit signals:

property::image When the image value changes.

self wibox.widget.imagebox The object which changed (useful when connecting many object to the same callback).

clip_shape (function or gears.shape) · 1 signal

Set a clip shape for this imagebox. A clip shape define an area where the content is displayed and one where it is trimmed.

Type constraints:

clip_shape function or gears.shape A gears.shape compatible shape function.

Emit signals:

property::clip_shape When the clip_shape value changes.

self wibox.widget.imagebox The object which changed (useful when connecting many object to the same callback).
new_value clip_shape The new value affected to the property.

resize (boolean) · 1 signal

Should the image be resized to fit into the available space?

Usage example

Click to display more

Emit signals:

property::resize When the resize value changes.

self wibox.widget.imagebox The object which changed (useful when connecting many object to the same callback).
new_value resize The new value affected to the property.

children (table) · Inherited from wibox.widget

Get or set the children elements.

Type constraints:

children table The children.

all_children (table) · Inherited from wibox.widget

Get all direct and indirect children widgets. This will scan all containers recursively to find widgets Warning: This method it prone to stack overflow id the 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

Force a widget height.

Type constraints:

height number or nil The height (nil for automatic)

forced_width (number or nil) · Inherited from wibox.widget

Force a widget width.

Type constraints:

width number or nil The width (nil for automatic)

opacity (number) · Inherited from wibox.widget

The widget opacity (transparency).

Type constraints:

opacity number The opacity (between 0 and 1) (default 1)

visible (boolean) · Inherited from wibox.widget

The widget visibility.

buttons (table) · Inherited from wibox.widget

The table contains a list of awful.button objects.

Object methods

:set_image (image)

Set the imagebox image.

The image can be a file, a cairo image surface, or an rsvg handle object (see the image property).

Parameters:

image image The image to render.

Set a declarative widget hierarchy description. See The declarative layout system

Parameters:

args An array containing the widgets disposition

:add_button (button) · Inherited from wibox.widget

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

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.

Parameters:

signal_name string
... Other arguments

: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().

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.
