I'm trapped the "release key" event but for certain keys, treeview emits a beep (left or right arrow, del keys). How can I remove this "beep" ?
Ohai, Raum. I cannot reproduce the beep with the sample you provided. On some systems, the TreeView emits beeps, when it cannot do what the user commands it to, for example if you press [Arrow Up] and there is no row above the current row, so the move-one-row-higher action cannot be completed properly. I had this behaviour on my old Laptops in Gtk-Applications like Pidgin and others. I never really considered the beeping a problem, but it stopped when i reinstalled the OS at some point. So i think, that this is a configuration problem. Regards, Grindhold
