  local self = self
  print(db_glob.name)
  local mainpanel = initPanel()
  initSlashCmd(mainpanel)
  self:UnregisterEvent("PLAYER_LOGIN")
end
 
--CALL
 
--by doing this the addon will call functions based on registered events by itself
addon:SetScript("OnEvent", function(self, event)
  self[event](self)
  --return self[event](self)
end)
--register events
addon:RegisterEvent("VARIABLES_LOADED")
addon:RegisterEvent("PLAYER_LOGIN")

Result is a blank panel.
Example shows loading the DB, creating the panel/subpanel and adding a slashcmd to call the panel.
