Class awful.widget.taglist

Taglist widget module for awful

Here is a more advanced example of how to extent the taglist.

It provides:

  • mouse “hover” color
  • an extra index field
  • a powerline look and feel

Usage example

s.mytaglist = awful.widget.taglist {
    screen  = s,
    filter  = awful.widget.taglist.filter.all,
    style   = {
        shape = gears.shape.powerline
    },
    layout   = {
        spacing = -12,
        spacing_widget = {
            color  = '#dddddd',
            shape  = gears.shape.powerline,
            widget = wibox.widget.separator,
        },
        layout  = wibox.layout.fixed.horizontal
    },
    widget_template = {
        {
            {
                {
                    {
                        {
                            id     = 'index_role',
                            widget = wibox.widget.textbox,
                        },
                        margins = 4,
                        widget  = wibox.container.margin,
                    },
                    bg     = '#dddddd',
                    shape  = gears.shape.circle,
                    widget = wibox.container.background,
                },
                {
                    {
                        id     = 'icon_role',
                        widget = wibox.widget.imagebox,
                    },
                    margins = 2,
                    widget  = wibox.container.margin,
                },
                {
                    id     = 'text_role',
                    widget = wibox.widget.textbox,
                },
                layout = wibox.layout.fixed.horizontal,
            },
            left  = 18,
            right = 18,
            widget = wibox.container.margin
        },
        id     = 'background_role',
        widget = wibox.container.background,
        -- Add support for hover colors and an index label
        create_callback = function(self, c3, index, objects) --luacheck: no unused args
            self:get_children_by_id('index_role')[1].markup = '<b> '..index..' </b>'
            self:connect_signal('mouse::enter', function()
                if self.bg ~= '#ff0000' then
                    self.backup     = self.bg
                    self.has_backup = true
                end
                self.bg = '#ff0000'
            end)
            self:connect_signal('mouse::leave', function()
                if self.has_backup then self.bg = self.backup end
            end)
        end,
        update_callback = function(self, c3, index, objects) --luacheck: no unused args
            self:get_children_by_id('index_role')[1].markup = '<b> '..index..' </b>'
        end,
    },
    buttons = taglist_buttons
}

As demonstrated in the example above, there are a few “shortcuts” to avoid re-inventing the wheel. By setting the predefined roles as widget ids, awful.widget.common will do most of the work to update the values automatically. All of them are optional. The supported roles are:

awful.widget.common also has 2 callbacks to give more control over the widget:

  • create_callback: Called once after the widget instance is created
  • update_callback: Called everytime the data is refreshed

Both callback have the same parameters:

  • self: The widget instance (widget).
  • t: The tag (tag)
  • index: The widget position in the list (number)
  • tags: The list of tag, in order (table)
