# Label

A simple label

#include <gtk/gtk.h>

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

/*Create a window with a title and a default size*/ window = gtk_application_window_new (app); gtk_window_set_application (GTK_WINDOW (window), GTK_APPLICATION (app)); gtk_window_set_title (GTK_WINDOW (window), "Welcome to GNOME"); gtk_window_set_default_size (GTK_WINDOW (window), 200,100);

/*Create a label and set its alignment. Setting the line wrap to TRUE makes the label break lines if the text exceeds the widget's size. When set to FALSE the text gets cut off by the edge of the widget*/ label = gtk_label_new ("Hello GNOME!"); gtk_label_set_justify (GTK_LABEL (label), GTK_JUSTIFY_CENTER); gtk_label_set_line_wrap (GTK_LABEL (label), TRUE);

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

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; }

In this sample we used the following:

GtkApplication
