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

[Kjell Ahlstedt <kjell ahlstedt bredband net>]

Hello Phong Cao,

1. I compiled and run your program. It started without an error.
2. I renamed the file now-playing.png so the program would not find it.
Then I got the same abrupt termination as you got.
3. I restored the file name, and started the program from another
directory. Then it also terminated with Glib::FileError. This is
probably what happened to you.

Gdk::Pixbuf::create_from_file("now-playing.png") searches for the file
in the current directory, which is the directory from where the program
was started. That's not necessarily the directory where the program's
executable file is stored.

You need to call a function that tells you where your executable is
stored (search path, not just filename). Unfortunately I don't know
which function is appropriate. Perhaps someone else knows?
