Handler classes are instantiated in the following state:
|
|
- the widget tree is created, but not yet realized (no toplevel window.show() executed yet)
|
|
- the halcomp HAL component is set up and the widhget tree's HAL pins have already been added to it
|
|
- it is safe to add more hal pins because halcomp.ready() has not yet been called at this point.
|
|
|
|
after all handlers are instantiated in command line and get_handlers() order, callbacks will be
|
|
connected with connect_signals()/signal_autoconnect()
|
|
|
|
The builder may be either of libglade or GtkBuilder type depending on the glade file format.
