I have a GtkSourceView widget with some text, it works fine.
I'd like to change the contents of the associated text buffer when the user resizes the view widget; I am having trouble doing this reliably. What is the preferred method?
The SourceView widgets are inside a GtkPaned, that can be resized either by the user moving the splitter, or when the container window changes size.
Connect to the source view's size-allocate signal (with g_signal_connect_after()) and change the contents of the buffer at that point.
