Just FWIW, can we agree on one meaning of "transactional"?
For me, the fact that the model shouldn't have to know about the number of
views showing it has nothing to do with transactionality:

The mechanism i'd implement would be:

and add an interface to it for being a DND-proxy (that's easiest done

Fonts are now being handled by Pango and drawing can happen either directly
through Cairo:
http://library.gnome.org/devel/pango/1.20/pango-Cairo-Rendering.html
or the Style API (note to use the *_paint_* variants, e.g. gtk_paint_layout,
not _draw_layout):

I don't believe that using set_parent() will actually place the widget
inside the container; try gtk_container_add(GTK_CONTAINER(grid), widget);

You could try RefDbg: http://refdbg.sourceforge.net/
It's a debugger specifically written for the task of debugging GObject

What is probably better is to use gdk_flush() after the execution of
gtk_window_move() or _resize(), and after that make sure that you run the
main event loop with gtk_main_iteration(); you can use a GTimer to determine
the time elapsed. Obviously, and also since this involves the windowing
system

Yes an UTF-8 string a NULL-terminated ASCII-compatible string. For all
purposes except where you need to read it character-by-character (e.g.
Gtk+/Pango "reading" the string to display it), you can just treat it like a
normal ASCII string.

A function is just a piece of code, so if you call a function in T1 from T2,
you still call it in the context of T2; the only thing really helping here
is having a maincontext in T1 and T2, and using a g_idle_add() *on* the
maincontext of T1 (but the code that adds it can be called from T2) so the
I think he meant that in order to use the function with g_signal_connect(),
a C linkage is not needed (and i think this is actually right, too).

That does indeed mean it; it's what Emmanuele supposed and it turns out to

It's rather strange for a gtk+ app to do this, is there some kind of other
non-glib-based main loop running?

You could use expose regions and in case the lasso size changes, only redraw
the previous area covered by the lasso (i don't mean the full area btw but
simply the areas covered by the lasso lines, so maybe "lines" would be more
appropriate than "area").
For reference see:

Sounds really odd if it's a ComboBoxText. Could you make all of the
code available somewhere?

You can use gtk_label_set_markup() and set the internal Layout of the

Something like you take the coordinates at press, and on subsequent motion
events you take the coordinates again,
with the velocity depending on the position/distance from the original
coordinates. On "unpress" (release) you
stop the scroll.
No?

The symbols must be non-mangled (look up C++ symbol mangling on Google), or,
but this is really only theoretical, you would need to provide the already

The problem seems to be that you're using Cairo to render the text but use
Pango to calculate the text extents. This doesn't make a lot of sense to me.
Just use Pango for everything, or just use Cairo for everything (it has
functionality to determine extents of text layouts as well), that should f

You need to get the TreeSelection from the TreeView and connect to
that's "changed" signal, and make sure you connect_after.

No, sorry there's really no way to do this. The decoration is (as of yet;
there have been proposals in the past) not handled by Gtk+ but by the WM or
a decorator, and can thus only be enabled or disabled wholesale.
