Hi,
i recall having struggled with a file chooser some years ago,
but after some iterations got something that worked for me
for simple file operations. It was however impossible at that
time to tell the file chooser to open a file OR a dir so i ended
reinventing the wheel and wrote my own file
Hi all,
I have done some further experimentation with regard to my GtkFileChooser
problem and discovered that the piece of my code that seems to be
triggering this problem is the call to gtk_file_chooser_set_current_name()
-- if I remove that then I do not get the error described in my last

I am having a problem with GtkFileChooser when the chooser action is set to
GTK_FILE_CHOOSER_ACTION_CREATE_FOLDER, i.e., I want to allow the user to

that use of GTK_FILE_CHOOSER_ACTION_CREATE_FOLDER:

Thanks for all the further explication, Chris!
The problem is that the main loop would enter a busy loop. Well, maybe
a 'busy-ish' loop. If you call up g_idle_add() with a repeating
callback (one which returns TRUE) which does nothing except examine a
non-blocking select(), you will end up w
Hi Roger,

Hi all,
I need to monitor a Unix file descriptor for input within my gtk3 program.
I believe that I need to somehow be using g_source_add_unix_fd() and
friends but am finding the documentation confusing. Are there any simple
examples which show how to do this anywhere? (I looked but could not
Thanks much for the suggestions and code pointer, Eric!
I get the drift that GSubProcess is a more recent package layered over
g_spawn. It consequently seems to have more features but less 3rd-party
documentation outside the reference manual.

Hi Emmanuele,
On closer reading there are some details of GSubProcess implementation and
usage that are unclear to me. I have not been able to find anything
resembling a tutorial anywhere, if you are aware of anything useful other
