SUJET: ScrolledWindow and copy_to_image(...)
DATE: Wed, 22 Nov 2006 17:21:40 +0100
Hello,
I'm currently developing an application that is nearly a viewer.
I've done a main class deriving from Gtk::Window that is my application.
Inside of it I add toolbar, menubar and a Gtk::ScrolledWindow.
In the scrolledWindow, I've add a Gtk::Layout deriving class.
An any time, I would like to save all the layout in a file.
For this, I've done this :
void on_export()
{
guint width, height;
Glib::RefPtr<Gdk::Window> gwin = get_window();
get_size( width, height );
Glib::RefPtr<Gdk::Image> img = Gdk::Image::create( Gdk::IMAGE_NORMAL,
Gdk::Visual::get_system(),
width,
height );
img = gwin->get_image(0,0, width, height );
std::cout << "here" << std::endl;
Glib::RefPtr<Gdk::Pixbuf> mbuff = Gdk::Pixbuf::create( img,
Gdk::rgb_get_colormap(),
0, 0,
0, 0,
width,
height );
mbuff->save("toto.png", "png");
}
But it doesn't do what I want,as it exports only the visible area of my
Layout.
Does someone can help me in doing the exportation of all the layout ?
Thanks,
