Re: terminate called after throwing an instance of 'Glib::FileError'

[Phong Cao <phngcv gmail com>]

Thank you guys for the responses!

I am not sure why this happened but when I clicked on the executable file the program ran. However, when I started it using Terminal, the program got error again. Anyway I think I just started it directly then...

BTW, does anyone know how to create a Gtk::Button that contains Stock image. In other words, do you know how to create a GtkStockButton without label?

Hello,

You may play with these functions :
http://developer.gnome.org/glibmm/unstable/group__MiscUtils.html

You may see in argv[0] if the program was launched with a path
(./debug/foo), and then use build_path & others to construct your image
path name. Using find_program_in_path will help you if the user lauched
it from nowhere because it's in the path.
Using get_(system|user)_data_dirs may help if the program is installed.

And using Glib::File::query_exists() before calling create_from_file
will prevent throwing an exception (useful to search your file through
directories ;))

A linux-only application may read /proc/PID/exe, but it's not portable,
and you may use gtk for this ;)
