^ add a tab to this tabview
^ tab:
{
name = "tabname", -- name of tab to create
caption = "tab caption", -- text to show for tab header
cbf_button_handler = function(tabview, fields, tabname, tabdata), -- callback for button events
--TODO cbf_events = function(tabview, event, tabname), -- callback for events
cbf_formspec = function(tabview, name, tabdata), -- get formspec
tabsize =
{
x, -- x width
y -- y height
}, -- special size for this tab (only relevant if no parent for tabview set)
on_change = function(type,old_tab,new_tab) -- called on tab change, type is "ENTER" or "LEAVE"
}
- set_autosave_tab(value)

dialog_create(name, cbf_formspec, cbf_button_handler, cbf_events)
^ create a dialog component
^ name: name of component (unique per ui)
^ cbf_formspec: function to be called to get formspec
function(dialogdata)
^ cbf_button_handler: function to handle buttons
function(dialog, fields)
^ cbf_events: function to handle events
