Note on API changes to class handlers and persistence.py:
Class handlers:
===============
The 'panel' parameter was dropped from get_handlers() since it's not needed.
Correspondingly, the handler class __init__() method does not get this
parameter any more as well:
class HandlerClass:
...
def __init__(self, halcomp,builder,useropts):
self.halcomp = halcomp
self.builder = builder
def get_handlers(halcomp,builder,useropts):
return [HandlerClass(halcomp,builder,useropts)]
Widget access in handler classes:
=================================
For a named widget, use:
w = self.builder.get_object("widgetname")
To retrieve a list of all widgets in the UI file, use:
wl = self.builder.get_objects()
This works regardless wether the UI is in libglade or GtkBuilder format.
persistence.py
==============
The handling of the builder parameter has been simplified. It has been dropped
from the save_state and restore_state methods, and added instead to the
IniFile.__init__() method. Therefore, use as follows:
class HandlerClass:
...
def on_destroy(self,obj,data=None):
# note: save_state(<object to fetch attributes from>) only:
self.ini.save_state(self)
def __init__(self, halcomp,builder,useropts):
self.halcomp = halcomp
self.builder = builder
self.ini_filename = __name__ + '.ini'
self.defaults = { IniFile.vars: dict(),
IniFile.widgets : widget_defaults(select_widgets(self.builder.get_objects(), hal_only=False,output_only = True))
}
# note extra self.builder parameter
self.ini = IniFile(self.ini_filename,self.defaults,self.builder)
# note - only the object which gets attributes set is passed:
self.ini.restore_state(self)
All examples and templates have been adapted accordingly.
