Hi,
I'm writing a small application, which should display a window with an
image in it, with out window borders (similar to splash window).
I'm trying to add image to the window using add () function
here pix is const Glib::RefPtr<Gdk::Pixbuf>&
=============
Gtk::Image *image = new Gtk::Image (pix) ;
add (*image) ;
image->show() ;
=============
This works fine. But the memory allocated to image is lost. I've to
retrieve it.
So i've done like this
=============
Gtk::Image image (pix) ;
add (image) ;
image.show() ;
=============
But when i do this, the image is not visible. (Reason could be , after
the function, image will be out of scope and will be destroyed, as its
not a pointer
The same thing happens, if i use auto_ptr also
=============
std::auto_ptr<Gtk::Image> image (new Gtk::Image (pix))
add (*image) ;
image->show() ;
=============
what am i doing wrong. Its very much possible, that i'm doing a very
silly mistake, or i must have not understood the basics of c/c++ well.
If i use pointer, how to free the memory allocated to it.
Thx,
Surya

Hey Surya,
If you write your initial code this way:
Gtk::Image *image =
manage(new Gtk::Image (pix));
add (*image) ;
image->show() ;
Then the memory allocation for your image will be handled by the
container into which you insert it and you won't have to worry about
deleting the storage.
