Problems Panning/Clicking with GtkIconView

Hi everyone,

I am having a hell of a time trying to get an GtkIconView working correctly
with the pannable area widget. Using hildon.GtkIconView I am able to pan by
using the scrollwheel on my mouse, but if i click anywhere to start panning,
it immediately activates whatever was clicked on. gtk.IconView does pretty
much exactly the same thing. Removing the connect function obviously allows
you to pan freely.

Code is as follows (I've left in various settings etc for completeness'
sake):
------------
pan_area = hildon.PannableArea()
model = gtk.ListStore(str, gtk.gdk.Pixbuf)

for item in xmlf:
thumbnail_data = gtk.gdk.pixbuf_new_from_file(
cache_path_thumbs + item["filename"])
model.append([str(item['name']), thumbnail_data])

grid = hildon.GtkIconView(gtk.HILDON_UI_MODE_NORMAL, model)
grid.set_selection_mode(gtk.SELECTION_SINGLE)
grid.set_pixbuf_column(1)
grid.set_columns(4)
grid.set_item_width(190)
grid.set_spacing(thumbnail_spacing)
grid.connect('selection-changed', self.thumbnailSelect, model, window)
pan_area.add_with_viewport(grid)
------------

Points of note: I'm using the Vmware SDK. I know that has a few bugs so
maybe this is one of them. As mentioned, the scrollwheel does pan the area,
so pannable area is working as intended.

Does anyone have any ideas? this is a pretty critical issue and I don't know
of anyone else who's managed to get this working.

What am I doing wrong?

Thanks!

Hi Jonathan,

which VMWare image and SDK are you using? This was an issue in the Beta
SDK and with the Final SDK it should work.

Cheers Daniel

Re: Problems Panning/Clicking with GtkIconView [In reply to]

Hi Daniel,

I'm using the PreFinal from http://maemovmware.garage.maemo.org/ -
Does that sound like it would be the cause of my problems?

Cheers
Jon

The PreFinal vmware image contains the Final Maemo SDK. So I guess the
answer is no. Just a guess though...

I've tested on a N900 ande it's exactly the same behavior.

Does anybody know how this could be achieved?

Thanks

Re: Problems Panning/Clicking with GtkIconView [In reply to]

The solution to this, thanks to zaheerm on talk.maemo.org -
http://talk.maemo.org/showthread.php?t=34369:

----
1st change your event connection to be "item-activated" not "selection-changed"
2nd no need to set the selection mode
3rd don't add the grid with add_with_viewport, instead use add
----

Cheers!
Jon
