GTK 创建最简单的一个创建窗口的示例

程序代码：

#include <gtk/gtk.h>

//PROTOTYPES

void CloseRequest(GtkWidget *theWindow, gpointer data);

gint main(gint argc,gchar *argv[])

{

    GtkWidget *window;

    //get GTK+ to process the startup arguments

    gtk_init(&argc,&argv);

    //create the app’s main window

    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

    //connect a window’s signal to a signal function

    gtk_signal_connect(GTK_OBJECT(window),“destroy”,GTK_SIGNAL_FUNC(CloseRequest),NULL);

    gtk_widget_show(window);

    gtk_main();

    return 0;

}

//function to handle a close signal on the window

void CloseRequest(GtkWidget *theWindow,gpointer data)

{

    gtk_main_quit();

}

程序编译：

gcc –Wall –o test main.c `pkg-config gtk+-2.0 –libs –cflags`
