RE: Unable to catch Gdk::PixbufError

[J B C Engelen ewi utwente nl]

I have written a simple program to demonstrate the problem. It is given
below. The program must be run like: pixbuferror.exe test.jpg.
1. If test.jpg does not exist, I get this : "terminate called after
throwing an instance of 'Glib::FileError'"
2. If test.jpg does exit but is not a valid file : "terminate called
after throwing an instance of 'Glib::Error'"
3. If test.jpg is valid, the program shows "Succes!!!" indicating that
it at least did not crash. It does show some glibmm warnings but that is
because things are probably not initialised properly.

Since I really do not know how to initialise gdk and friends properly, I
have stopped trying and hope you can work with this little program. In
any case, the program does not catch exceptions which I find really
strange.

Thanks for all the help,
Johan

----------------------------
the program: pixbuferror.cpp
----------------------------

#include <glibmm/ustring.h>
#include <gdkmm/pixbuf.h>
#include <gtk/gtk.h>

int main(int argc, char **argv) {
    Glib::ustring fileName = argv[1];

    //Get some image info. Smart pointer does not need to be deleted
    Glib::RefPtr<Gdk::Pixbuf> img(NULL);
    try {
        img = Gdk::Pixbuf::create_from_file(fileName);
    }
    catch (const Glib::FileError & e)
    {
        g_message("caught Glib::FileError");
        return -1;
    }
    catch (const Gdk::PixbufError & e)
    {
        g_message("Gdk::PixbufError");
        return -1;
    }
    catch (...)
    {
        g_message("Caught ... ");
        return -1;
    }

    g_message("Succes!!!");

    return 0;
}
