Why is always one textview item selected in HILDON_UI_MODE_EDIT?

Hi,

i have a simple treeview inside a pannable area. What i want to achieve is basically simple:
I want the user to be able to select one item and that item should stay selected until
the user selects a different item. Initially nothing should be selected.

Exactly this is the standard behaviour in gtk. In hildon, however i need to enable edit
mode to make something stay selected after the user clicked on it. There's a problem
with this: Initially the first item is automatically selected by some magic in this mode.
I even immediately get a "changed" event from the selection once the widget is being
created.

How do i prevent this? Even explicitely unselecting everything using
gtk_tree_selection_unselect_all() doesn't help. The first item stays selected. This is
bad since i was something to happen once the user selects an item. The user might
thus not be aware that he also needs to click onto the already selected first item if
he wants that first item to act.

Anybody else facing this problem? How can i deselect everything in a treeview in
state HILDON_UI_MODE_EDIT?

Regards,
Till

I was having the same problem with a GtkIconView and resorted to calling
gtk_icon_view_unselect_all after showing the widget. I still get the
selected events, though.

Doesn't that work? That's what GTK_SELECTION_BROWSE is for.

See hildon-touch-selector-normal-mode-example.c

It's GTK_SELECTION_SINGLE what i want. But single behaves like
browse on Maemo5 in a pannable area.

That example is not using edit mode but normal mode. Normal mode
doesn't work for me as it immediately de-select everything you select.

Hi,

that's pretty exact also my solution. In the first change event i receive
i just deselect everything and don't fo any further processing.
