A topic probably interesting to hackers working in sugar-toolkit: If I start Read without selecting a file, will try to open a ObjectChooser to select the file: But after the port crash with a error: 1320441958.125536 ERROR dbus.connection: Unable to set arguments (<ReadActivity object at 0x282f960 (readactivity+ReadActivity at 0x28bd020)>, 'Text') according to signature u'is': <type 'exceptions.TypeError'>: an integer is required Traceback (most recent call last): File "/home/gonzalo/sugar-jhbuild/install/bin/sugar-activity", line 147, in <module> main() File "/home/gonzalo/sugar-jhbuild/install/bin/sugar-activity", line 142, in main instance = create_activity_instance(activity_constructor, activity_handle) File "/home/gonzalo/sugar-jhbuild/install/bin/sugar-activity", line 35, in create_activity_instance activity = constructor(handle) File "/home/gonzalo/Activities/Read.activity/readactivity.py", line 335, in __init__ self._show_journal_object_picker() File "/home/gonzalo/Activities/Read.activity/readactivity.py", line 569, in _show_journal_object_picker result = chooser.run() File "/home/gonzalo/sugar-jhbuild/install/lib/python2.7/site-packages/sugar3/graphics/objectchooser.py", line 86, in run self._chooser_id = journal.ChooseObject(self._parent_xid, what_filter) File "/usr/lib/python2.7/site-packages/dbus/proxies.py", line 68, in __call__ return self._proxy_method(*args, **keywords) File "/usr/lib/python2.7/site-packages/dbus/proxies.py", line 140, in __call__ **keywords) File "/usr/lib/python2.7/site-packages/dbus/connection.py", line 620, in call_blocking message.append(signature=signature, *args) TypeError: an integer is required The code in Read is: chooser = ObjectChooser(_('Choose document'), self, Gtk.DialogFlags.MODAL | Gtk.DialogFlags.DESTROY_WITH_PARENT, what_filter=mime.GENERIC_TYPE_TEXT) try: result = chooser.run() and apparently the problem is with the parameter "parent". I can put: chooser = ObjectChooser(_('Choose document'), None, Gtk.DialogFlags.MODAL | Gtk.DialogFlags.DESTROY_WITH_PARENT, what_filter=mime.GENERIC_TYPE_TEXT) and the activity will start, but with gtk2 sugar-toolkit we had a problem when the activities do not set the parent, and the dialog was over any activity, if the user change the activity. In the code of ObjectChooser in the gtk3 branch of sugar toolkit there is the following code: if parent is None: parent_xid = 0 elif hasattr(parent, 'window') and hasattr(parent.window, 'xid'): parent_xid = parent.window.xid else: parent_xid = parent but the activity do not have a window and if I replace with get_window, I couldn't find xdi. Any idea about what to do with this issue?
