I am using GtkPlug/GtkSocket on a large space system program. It turned
out to be incredibly useful to us. We have a docked window at the top
of the screen that displays a summary of system status. This docked
window has four GtkSockets that are plugged by four other applications.

BTW, if anyone has a better way of tracing memleaks in glib/gtk based apps,
without valgrind or using it in another way, steps are welcome!

I created a simple gtk app that uses all the widgets and
functions that we use across our many GUIs. I ran that app with purify, and
created a suppression file to suppress all of the reported errors from this
simple app. I use that same suppression file when running the production
GUIs, so
I'll never understand why Glade removed the code gen capability when it
went from Glade2 to Glade3. Most of the time, the XML UI definition is
best, but not in cases like yours.
If startup performance is vital, I recommend manually coding via the
widget API. However, a good portion of your

That is controlled by the window manager's theme, not GTK+. However, if
you want to do extra work, you can call
gtk_window_set_decorated(window,false) and design your own window
title/border.

Only if the member function is static. Calling a non-static member
function requires two addresses: the instance address and the function
address. Whether its public or private doesn't matter because access to
function pointers is not checked by compilers. I frequently do

I am populating a tabular GtkTreeView using a GtkListStore and a
GtkTreeModelSort for sorting. I use

gtk_tree_sortable_set_sort_func() to allow some of my columns to be
sorted using a custom sort function.
I noticed that while a column is being
When you want vertical or horizontal alignment, use GtkVBox or GtkHBox.
For both vertical and horizontal alignment, use GtkTable.
Also, you may find it useful to design GUIs with glade. Even if you
don't use it for XML or code gen, it will quickly point you in the right
direction for layout
gdk_gc_new(your_widget-window) will allocate a graphics context that
you can use to draw a rectangle. You should call gdk_gc_unref() when
you are done with it.
Alternatively, you could just create a GtkEventBox and use
gtk_widget_modify_bg().

Interesting. So g_idle_add can be safely called
from a different thread? Does it have to be a gthread,
or will a pthread work as well?
I have been using pthreads with g_idle_add for a few years. It seems to
work fine. Just make sure you call g_thread_init(NULL) before
gtk_main().
I've
You do not need to call gdk_thread_init()
if you are only invoking GDK/GTK+ functions by message passing via
g_idle_add() (that is, if you are not calling
gdk_threads_enter()/leave()).
That's interesting. g_idle_add() is thread safe without telling it to
use mutex locking? Based on the

I think your best bet is to isolate the problem down to a small amount
of stand-alone code. You will most likely discover the problem in the
process of isolation. If you don't, re-post the isolated code (the
smaller the better), and I'll take a look again.
