There are two applications :
'Caller', that will call a given number
'Dialer', that let you type a number and then invoke 'Caller'
So in your case you want to use 'Caller' and not 'Dialer'
But in fact you can simply use the 'Caller' service, for example
to call the number '01234' from within a tichy tasklet :
yield tichy.Service('Caller').call(window, '01234')
[where window is the parent window you want to use for the dialer, with
etk or gtk backend it will be ignored since all app start in a new
if you don't run from a tasklet, you can still invoke it like this :
[where `on_return` and `on_error`, are two optional callback functions
that will be called when the caller service is done]
But now, to really really do things in a nice way, you can even directly
use the tichy.Contact item, that already defines the 'Call' action.
So if you want to show a contact and let the user being able to initiate
a call, you can write :
actor = contact.create_actor()
Now depending of the 'Design' service that may do different things. The
default design will try to show a button with the contact name (plus an
optional icon), when the user click on the contact, it will pop up a
menu with the different possible actions on a contact (including 'Call')
Anyway, depending on what you want to do you can use or not those
