GridView deselect (original) (raw)

Hi,

I’m using GtkGridView in a GTK4 app, what I’m trying to achieve is to deselected all selected items when clicking in a place where there’s no item.

Is there any way to achieve this?

Currently, what I can think of is calling Gtk.SelectionModel unselect_all on some signal, but I can’t find any signal matching my needs (ie. that fires when clicking outside any item).

In GTK3, Gtk.IconView had a method get_item_at_pos which could be used to determine if a click was outside an item, but this method doesn’t seem to be available in Gtk.GridView in GTK4. I’ve tried using a Gtk.GestureClick to capture click events and determine the click position, but I’m struggling to find a reliable way to check if the click is indeed outside any items.

Hi,

Yes, use a GestureClick, then call Gtk.Widget.pick to get the widget under the click coordinates. If it returns the gridview itself (or maybe NULL, I can’t remember), then you clicked in an empty area.

Works like a charm: it does return the Gtk.Gridview when clicking an empty area. Thanks a lot!
