[java-gnome-hackers] Problem with TextIter / Generator

[Stefan P. <st...@pr...>]

Hi all!

First of all: Andrew "tricked" me into having a closer look at the
sources and do needed coverage of GTK methods myself, so I just found
myself digging through the sources. I hope I can help you add some
coverage in the future.

I started working on coverage for TextBuffer/TreeView and friends and
nearly immediately stumbled into my first problem, for which I request
your advice.

I want to write a method
  TextIter TextBuffer.getStartIter()

Having a look at GtkTextBuffer I found
  static final void getStartIter(TextBuffer self, TextIter iter) {
    ..
    gtk_text_buffer_get_start_iter(pointerOf(self), pointerOf(iter));
    ..
  }

So, I need an instance of a TextIter to call that method - but where do
I get that from? Normally I would expect a native method like 
  gtk_text_iter_new
but it seems that it does not exist.

The GTK API docs claim that "... GtkTextIter is a struct designed to be
allocated on the stack; ...", so normally I would call it like
  GtkTextIter start_iter;
  GtkTextBuffer foo = ...;
  gtk_text_buffer_get_start_iter (&foo, &start_iter);

This is basically what is in GtkTextBuffer.c 
Java_org_gnome_gtk_GtkTextBuffer_gtk_1text_1buffer_1get_1start_1iter
except that that method requires a pointer to a GtkTextIter, although it 
should be the method to create one.

Manually patching GtkTextBuffer.c is out of the question, since it is 
generated, so now I am stuck.

Can anyone shed some light on this. Did I miss something? Any idea how to 
solve this?
