Re: Gtk3 text view anchored in text view cannot get cursor inside (Ok in Gtk2)

[Giuseppe Penone via gtk-list]

Hi Eric,

thanks for looking at the problem, in fact it looks like stopping the event
to reach the below text view does the trick:

textViewNested.signal_button_press_event().connect([](GdkEventButton*
pEvent){ return true; });

Cheers,
Giuseppe.

 Hi Giuseppe,

It looks like you are going to need to set up a callback and grab the focus of 
that uncooperative nested textview. It should work with GTK3.

Re: Gtk3 text view anchored in text view cannot get cursor inside (Ok in Gtk2)

[Giuseppe Penone via gtk-list]

Hi Andres, in my application cherrytree I give the user the possibility to
have so called code boxes ( http://giuspen.com/cherrytreemanual/#_codebox )
so in between rich text you can have a syntax highlighted code box.
This is very appreciated from the end users and it's a pity that gtk3 does
not seem to support it while gtk2 did.
Regards,
Giuseppe.

The list is not really dead, but nobody is required to give you an answer:
this is not a paid support channel.

If you're not getting answers it may be the case that you're doing
something that nobody else is doing.

Ciao,
 Emmanuele.

I'm trying to understand what are you nesting two GtkTextView. What are
trying to get? I mean, GtkTextView is meant to show text from a buffer not
to contain another widget.

Is there no other desing that fit better with the porpuse of those widget
but still giving you something near to your original idea?

Please could somebody tell me where is the best place to report such

I also raised a bug on https://gitlab.gnome.org/GNOME/gtk/issues/1663 but
