launcher editor not working for me with 11.10

[Hunter VanHorn]

When pressing the add quicklist group button, the dialog comes up, but when the OK button is clicked, the new entry is not shown on the table, and logging out and back in does not show the new entry. The edit launcher button doesn't do anything at all.

Same problem with 11.10

Didn't realize how useless my report was until Anders posted his console output. Fixing that now, with comments on what buttons I was pressing when.

It looks like we are having a python version problem.
I will try to fix this soon.

Same problem here. Did a whole bunch of debugging this morning.

Apparently, gtk hates your signals because they're not specific enough. I changed the __gsignals__ dict in widgets/launcherview.py's LauncherView to this:

@@@
    __gsignals__ = {
                    "selection-changed" : (gobject.SIGNAL_RUN_LAST,
                                           gobject.TYPE_NONE,
                                           (gtk.ListStore,
                                            gtk.TreeIter,
                                            gobject.TYPE_OBJECT),),
@@@

That got things working a little better, but another error occured where the object emitted from the "selection-changed" signal is None. This problem stems from the "add_row" function in LauncherView where "new_iter = self.listmodel.append(row_data)" ever successfully executes because of a problem similar to the one above: the type of DesktopParser is wrong (not inherited from a GObject).

So, I created a very simple wrapper in core/desktop.py:
@@@
class DesktopParserWrapper(gobject.GObject):
    def __init__(self, parser):
        self._parser = parser
        gobject.GObject.__init__(self)
@@@

Problem almost solved. The only thing left is to change the LauncherView's listmodel to
@@@
        self.listmodel = gtk.ListStore(Pixbuf,
                              gobject.TYPE_STRING,
                              gobject.TYPE_OBJECT,
                              gobject.TYPE_STRING,
                              gobject.TYPE_STRING
                              )
@@@

and to change every call to "add_row" to use a DesktopParserWrapper instead of a DesktopParser. This last change is why I'm not just submitting a patch. There's simply too many of these and I don't know how the entirety of the program will react when I change them all.

In general, I have no idea why all of this change is required. Did GTK get a whole bunch more specific recently? gtk.ListStore seems to act... however it wants. I would guess that a gobject.TYPE_PYOBJECT would be fine for passing a DesktopParser, but, apparently it's not.

Some or all of this work may be unnecessary. This is just the result of my endless struggle with unity's launcher.

I am trying to add a script to the launcher under 11.10 and also running into errors. Steps to reproduce:

get unity-launcher-editor
cd ~/unity-launcher-editor
./ule
Click the "document plus" icon in the upper left.
click "Custom" tab
enter launcher name, command, comment, choose icon
click add.

nothing happens in the launcher, and I get a a couple of errors on the command line. See below:
