Class awful.popup - awesome API documentation

# Class `awful.popup`

An auto-resized, free floating or modal wibox built around a widget.

This type of widget box (wibox) is auto closed when being clicked on and is automatically resized to the size of its main widget.

Note that the widget itself should have a finite size. If something like a wibox.layout.flex is used, then the size would be unlimited and an error will be printed. The wibox.layout.fixed, wibox.container.constraint, `forced_width` and `forced_height` are recommended.

    awful.popup {
        widget = {
            {
                {
                    text   = 'foobar',
                    widget = wibox.widget.textbox
                },
                {
                    {
                        text   = 'foobar',
                        widget = wibox.widget.textbox
                    },
                    bg     = '#ff00ff',
                    clip   = true,
                    shape  = gears.shape.rounded_bar,
                    widget = wibox.widget.background
                },
                {
                    value         = 0.5,
                    forced_height = 30,
                    forced_width  = 100,
                    widget        = wibox.widget.progressbar
                },
                layout = wibox.layout.fixed.vertical,
            },
            margins = 10,
            widget  = wibox.container.margin
        },
        border_color = '#00ff00',
        border_width = 5,
        placement    = awful.placement.top_left,
        shape        = gears.shape.rounded_rect,
        visible      = true,
    }

Here is an example of how to create an alt-tab like dialog by leveraging the awful.widget.tasklist.

    awful.popup {
        widget = awful.widget.tasklist {
            screen   = screen[1],
            filter   = awful.widget.tasklist.filter.allscreen,
            buttons  = tasklist_buttons,
            style    = {
                shape = gears.shape.rounded_rect,
            },
            layout   = {
                spacing = 5,
                forced_num_rows = 2,
                layout = wibox.layout.grid.horizontal
            },
            widget_template = {
                {
                    {
                        id     = 'clienticon',
                        widget = awful.widget.clienticon,
                    },
                    margins = 4,
                    widget  = wibox.container.margin,
                },
                id              = 'background_role',
                forced_width    = 48,
                forced_height   = 48,
                widget          = wibox.container.background,
                create_callback = function(self, c, index, objects) --luacheck: no unused
                    self:get_children_by_id('clienticon')[1].client = c
                end,
            },
        },
        border_color = '#777777',
        border_width = 2,
        ontop        = true,
        placement    = awful.placement.centered,
        shape        = gears.shape.rounded_rect
    }

## Object properties

preferred_positions

  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:

      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:

      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:

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

  ### See also:

  - awful.placement.next_to
  - awful.popup.preferred_anchors
preferred_anchors

  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:

       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:

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

  ### See also:

  - awful.placement.next_to
  - awful.popup.preferred_positions
current_position
  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:

  - current_position string Either "left", "right", "top" or "bottom"
current_anchor
  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:

  - current_anchor string Either "front", "middle", "back"
hide_on_right_click
  Hide the popup when right clicked.

  ### Type:

  - hide_on_right_click boolean (default false)
minimum_width
  The popup minimum width.

  ### Type:

  - The number minimum width (default 1)
minimum_height
  The popup minimum height.

  ### Type:

  - The number minimum height (default 1)
maxmimum_width
  The popup minimum width.

  ### Type:

  - The number maxmimum width (default 1)
maximum_height
  The popup maximum height.

  ### Type:

  - The number maximum height (default 1)
offset

  The distance between the popup and its parent (if any).

  Here is an example of 5 popups stacked one below the other with an y axis offset (spacing).

      local previous = nil
      for i=1, 5 do
          local p2 = awful.popup {
              widget = wibox.widget {
                  text   = 'Hello world!  '..i..'  aaaa.',
                  widget = wibox.widget.textbox
              },
              border_color        = beautiful.border_color,
              preferred_positions = 'bottom',
              border_width        = 2,
              preferred_anchors   = 'back',
              placement           = (not previous) and awful.placement.top or nil,
              offset = {
                   y = 10,
              },
          }
          p2:move_next_to(previous)
          previous = p2
      end
