GTK编程

HelloGtk.c代码：

#include<gtk/gtk.h> void hello(GtkWidget *widget,gpointer data) { g_print("Hello Ubuntu!/n"); } gint delete_event(GtkWidget *widget,GdkEvent *event,gpointer data) { g_print ("delete event occurred/n"); return(TRUE); } void destroy(GtkWidget *widget,gpointer data) { gtk_main_quit(); } int main( int argc, char *argv[] ) { GtkWidget *window; GtkWidget *button; gtk_init (&argc, &argv); window=gtk_window_new (GTK_WINDOW_TOPLEVEL); gtk_signal_connect (GTK_OBJECT(window),"delete_event",GTK_SIGNAL_FUNC(delete_event),NULL); gtk_signal_connect (GTK_OBJECT (window), "destroy",GTK_SIGNAL_FUNC (destroy), NULL); gtk_container_set_border_width (GTK_CONTAINER (window), 10); button = gtk_button_new_with_label ("Hello Ubuntu!"); gtk_signal_connect (GTK_OBJECT (button), "clicked",GTK_SIGNAL_FUNC (hello), NULL); gtk_signal_connect_object (GTK_OBJECT (button), "clicked", GTK_SIGNAL_FUNC (gtk_widget_destroy), GTK_OBJECT (window)); gtk_container_add (GTK_CONTAINER (window), button); gtk_widget_show (button); gtk_widget_show (window); /*显示一个窗口*/ gtk_main(); /*进入主循环*/ return(0); }

编译链接：

gcc HelloGtk.c -o HelloGtk 'pkg-config --cflags --libs gtk+-2.0`

其中 pkg-config是一个命令，'pkg-config --cflags --libs gtk+-2.0`表示把gtk+-2.0这个包的所有相关的编译路径和库路径都列出来。

运行：

./HelloGtk
