Image (C) Monica Kochofar monicakochofar@gmail.com 2012 A widget displaying an image Fran Dieguez frandieguez@gnome.org 2012-2013. Image

This GtkApplication displays an image file from the current directory.

If the image file isn't loaded successfully, the image will contain a "broken image" icon. The filename.png needs to be in the current directory for this code to work. Use your favorite picture!

#include <gtk/gtk.h>



static void
activate (GtkApplication *app,
          gpointer        user_data)
{
  GtkWidget *window;
  GtkWidget *image;

  /*Create a window with a title and a default size*/
  window = gtk_application_window_new (app);
  gtk_window_set_title (GTK_WINDOW (window), "Welcome to GNOME");
  gtk_window_set_default_size (GTK_WINDOW (window), 300, 300);

  image = gtk_image_new_from_file ("gnome-image.png");

  gtk_container_add (GTK_CONTAINER (window), GTK_WIDGET (image));

  gtk_widget_show_all (GTK_WIDGET (window));
}



int
main (int argc, char **argv)
{
  GtkApplication *app;
  int status;

  app = gtk_application_new ("org.gtk.example",G_APPLICATION_FLAGS_NONE);
  g_signal_connect (app, "activate", G_CALLBACK (activate), NULL);
  status = g_application_run (G_APPLICATION (app), argc, argv);
  g_object_unref (app);
  return status;
}
