I have created an application on OS X El Capitan which has a GtkTreeView.
It has the start-interactive-search key binding, which works (the search bar is shown and focused) but nothing can be typed in it. Oddly enough, input can be copied, pasted or deleted, but when manually typing from the keyboard, the input is not shown.
I have even modified the 'Ctrl+f' key binding to something else and it still does not work.
Just in case, the properties 'can-focus' and 'has-focus' are set to true.
Any ideas?
Thanks!
