Hi,
could anyone please say if this should be considered a bug -- if so,
I'd file an issue at bugzilla:
* use win32 (not yet tested on linux)
* create toplevel window
* gtk_window_set_deletable(window,FALSE) [this is the critical part]
* place a FileChooserWidget into window
* show window
*
what does temporarily mean here:
gdk_threads_set_lock_functions: [...] When GTK+ unlocks the GTK+ lock
when entering a recursive main loop, the application must temporarily
release its lock as well.
What ever that means...

Imagine a simple window with 1 box and 2 buttons in it. If you press
the first button, the second is destroyed, and a newly created button
packed into the box. This *works* on linux and win32 (gtk+-2.10.13).
Now, let button 1 start a thread which does

Yes, the reason why idle functions work in any case is most probably
because they are running in the same thread as where gtk was

gtk_scrolled_window_set_shadow_type() works correctly, however,
probably not in the way the user expects: The function sets the shadow
type of the (outer) window, and leaves the (inner) shadow type of the
viewport as is.
So, if not created manually, the user never gets the viewport in her

Hi,
when glib spawns processes it starts a helper process first which
itself then starts the wanted process.
I've studied the gspawn(-win32).c and the win32 helper code, too,
however, I simply don't understand the need of the helper process. :-/
If made some tests with the Windows' _spawn*()

Hi,
here some remarks about the documentation of some g_slist* functions:

It is not explicitly said if the data which the element points to is

understand that, however, indirectly only.
