# 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; }

Neste exemplo empregaremos o seguinte:

GtkApplication

GtkWindow

GtkImage
