Functions
Methods- wibox.layout.fixed.horizontal (...)
-
Returns a new horizontal fixed layout. Each widget will get as much space as it
asks for and each widget will be drawn next to its neighboring widget.
Widgets can be added via :add() or as arguments to this function.
Note that widgets ignore forced_height. They will use the preferred/minimum width
on the horizontal axis, and a stretched height on the vertical axis.
- ... widget Widgets that should be added to the layout.
- wibox.layout.fixed.vertical (...)
-
Returns a new vertical fixed layout. Each widget will get as much space as it
asks for and each widget will be drawn next to its neighboring widget.
Widgets can be added via :add() or as arguments to this function.
Note that widgets ignore forced_width. They will use the preferred/minimum height
on the vertical axis, and a stretched width on the horizontal axis.
- ... widget Widgets that should be added to the layout.
Object properties

By default, no widget is used.
Type:
- widget
Usage:
-- Use the separator widget directly local w1 = wibox.widget { spacing = 10, spacing_widget = wibox.widget.separator, layout = wibox.layout.fixed.horizontal } -- Use a standard declarative widget construct local w2 = wibox.widget { spacing = 10, spacing_widget = { color = '#00ff00', shape = gears.shape.circle, widget = wibox.widget.separator, }, layout = wibox.layout.fixed.horizontal } -- Use composed widgets local w3 = wibox.widget { spacing = 10, spacing_widget = { { text = 'F', widget = wibox.widget.textbox, }, bg = '#ff0000', widget = wibox.container.background, }, layout = wibox.layout.fixed.horizontal } -- Use negative spacing to create a powerline effect local w4 = wibox.widget { spacing = -12, spacing_widget = { color = '#ff0000', shape = gears.shape.powerline, widget = wibox.widget.separator, }, layout = wibox.layout.fixed.horizontal }

Signals
- widget::layout_changed
-
When the layout (size) change.
This signal is emitted when the previous results of
:layout()

must return the same result when called with the same arguments.See also:
- widget::redraw_needed
-
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.See also:
