get_invisible_char

Retrieves the character displayed when visibility is set to false.

Note that GTK does not compute this value unless it needs it, so the value returned by this function is not very useful unless it has been explicitly set with [method@Gtk.Text.set_invisible_char].

Parameters:

this	a `GtkText`

Returns:

the current invisible char, or 0, if text does not show invisible text at all.
