HildonPannableArea + Eventbox(button-press-event) = click not pan

I have a grid of thumbnail images in a hildonpannablearea. In order to make the images clickable, I've put them in eventBox()es.

However, it turns out - at least in the SDK - this disables the panning functionality of the pannablearea, because as soon as you click to pan, it activates the event.

If you're confused as to what I mean, think of the image gallery in the n900 promo material.

So. Is this a bug or am I doing something horribly wrong?

Anyone know of a workaround? I need to make these images clickable...

Thanks everyone!

A quick suggestion: GtkIconView + HildonPannableArea (I don't know if it will work though).

GTK IconView works!

Here's the basic concept incase anyone searches for it:

Code:

model = gtk.ListStore(str, gtk.gdk.Pixbuf) # str is going to be our id field

model.append([item['id'], pixbuf_data]) # add to list..

gallery = gtk.IconView(model) # make it into an icon view

gallery.connect('selection-changed', self.selectThumb, model) # add signal thingy



def selectThumb(self, icon_view, model=None): 

selected = icon_view.get_selected_items()

i = selected[0][0]

self.awesomeFunction(model[i][0]) # passes id to our function (opens new window)

Actually, I was wrong about this. It doesn't work. Although it now allows you to pan, it still activated whatever was clicked when panning was initiated when you let go.

I don't know if this helps, the api for HildonPannableArea describes a property velocity-fast-factor as
Minimum velocity that is considered 'fast': children widgets won't receive button presses. Expressed as a fraction of the maximum velocity.

You could use GtkButtons with images inside a HildonPannableArea. That's probably not the style you're looking for, but it would get you started.

Also try asking this question on the developer mailing list. Some of the Hildon developers are there and usually provide good advice on problems like that.

Finally taken this to the maemo-developers list. Hopefully somebody there will have the answer. If so I'll post it.
