Emit signals:

property::bg When the bg value changes.

self naughty.layout.box The object which changed (useful when connecting many object to the same callback).

Consumed theme variables:

Theme variable	Usage

preferred_positions table or string · Inherited from awful.popup · 1 signal

Set the preferred popup position relative to its parent.

This allows, for example, to have a submenu that goes on the right of the parent menu. If there is no space on the right, it tries on the left and so on.

Valid directions are:

left
right
top
bottom

The basic use case for this method is to give it a parent wibox:

Usage example

for _, v in ipairs {"left", "right", "bottom", "top"} do
    local p2 = awful.popup {
        widget = wibox.widget {
            text   = "On the "..v,
            widget = wibox.widget.textbox
        },
        border_color        = "#777777",
        border_width        = 2,
        preferred_positions = v,
        ontop               = true,
    }
    p2:move_next_to(p)
end

As demonstrated by this second example, it is also possible to use a widget as a parent object:

Usage example

for _, v in ipairs {"left", "right"} do
    local p2 = awful.popup {
        widget = wibox.widget {
            text = "On the "..v,
            forced_height = 100,
            widget = wibox.widget.textbox
        },
        border_color  = "#0000ff",
        preferred_positions = v,
        border_width  = 2,
    }
    p2:move_next_to(textboxinstance, v)
end

Type constraints:

preferred_positions table or string A position name or an ordered table of positions

Emit signals:

property::preferred_positions When the preferred_positions value changes.

self awful.popup The object which changed (useful when connecting many object to the same callback).
new_value preferred_positions The new value affected to the property.

preferred_anchors table or string · Inherited from awful.popup · 1 signal

Set the preferred popup anchors relative to the parent.

The possible values are:

front
middle
back

For details information, see the awful.placement.next_to documentation.

In this example, it is possible to see the effect of having a fallback preferred anchors when the popup would otherwise not fit:

Usage example

 local p2 = awful.popup {
     widget = wibox.widget {
         text   = "A popup",
         forced_height = 100,
         widget = wibox.widget.textbox
     },
     border_color        = "#777777",
     border_width        = 2,
     preferred_positions = "right",
     preferred_anchors   = {"front", "back"},
 }
 local p4 = awful.popup {
     widget = wibox.widget {
         text   = "A popup2",
         forced_height = 100,
         widget = wibox.widget.textbox
     },
     border_color        = "#777777",
     border_width        = 2,
     preferred_positions = "right",
     preferred_anchors   = {"front", "back"},
 }

Type constraints:

preferred_anchors table or string Either a single anchor name or a table ordered by priority.

Emit signals:

property::preferred_anchors When the preferred_anchors value changes.

self awful.popup The object which changed (useful when connecting many object to the same callback).
new_value preferred_anchors The new value affected to the property.

current_position string · Inherited from awful.popup

The current position relative to the parent object.

If there is a parent object (widget, wibox, wibar, client or the mouse), then this property returns the current position. This is determined using preferred_positions. It is usually the preferred position, but when there isn't enough space, it can also be one of the fallback.

Type constraints:

current_position string Either "left", "right", "top" or "bottom"

current_anchor string · Inherited from awful.popup

Get the current anchor relative to the parent object.

If there is a parent object (widget, wibox, wibar, client or the mouse), then this property returns the current anchor. The anchor is the "side" of the parent object on which the popup is based on. It will "grow" in the opposite direction from the anchor.

Type constraints:

current_anchor string Either "front", "middle", "back"

hide_on_right_click boolean · Inherited from awful.popup · 1 signal

            widget = wibox.widget.textbox
        },

        preferred_positions = "bottom",
        border_width        = 2,
