Blinking cursor assertion when hiding widget

[Arjan Molenaar <arjan noterik nl>]

Hi,

I have some trouble with the blinking cursor feature. It aborts my app
if the text view doesn't have focus and I hide the text widget.

I use GtkTextView to edit text in DiaCanvas (just add it to the canvas
view (which is a GnomeCanvas / GtkLayout). The text view should hide
when it no longer has the focus. This, quite often causes in this
message:

Gtk-ERROR **: file gtktextview.c: line 4427 (blink_cb): assertion
failed: (GTK_WIDGET_HAS_FOCUS (text_view))

... followed by a core dump.

The question is: What is the best way to hide the text view when/after
it has lost it focus. I tried a idle callback, which works but is IMHO
not a very elegant solution. Doing a text_view.hide() or .destroy() in
the focus_out callback causes the app to dump core...

Any suggestions?

Thanks in advance,
