GTK+简介

GTK 最初为GIMP（一个图像处理软件，类似Photoshop）的工具包
后来GTK重写为面向对象的GTK+

GTK+ 并非是用C++写的，而是用C语言，所谓的面向对象是用C语言模拟的。强大

GTK+ 2.0 新特性：
使用Pango（a theme engine）增强了文本渲染
improved accessibility using the Accessibility Toolkit, transition to Unicode using UTF-8 strings, and a more flexible API.

GTK+ 2.8, GTK+ 2 depends on the Cairo graphics library for rendering vector graphics.

GTK+ 3.0
included revised input device handling, support for themes written with CSS-like syntax, and the ability to receive information about other opened GTK+ applications.

版本的新特性参考 wiki GTK+

编译

GTK+ 3.0的编译选项，用法见下文：
pkg-config --cflags gtk+-3.0
pkg-config --libs gtk+-3.0
https://developer.gnome.org/gtk3/stable/gtk-getting-started.html

fedora Linux中安装gtk+/gnome开发包：
dnf install gnome-devel
dnf install gtk3-devel
dnf install gtk2-devel
dnf install gtk+-devel
dnf install gcc
dnf install gcc-c++

#include <gtk/gtk.h>
void CloseRequest(GtkWidget* theWindow, gpointer data);

gint main(gint argc, gchar* argv[])
{
   
   
  GtkWidget* window;
  
  gtk_init(&argc, &argv);
  window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
  gtk_signal_connect(GTK_OBJECT(window), "destroy",
      GTK_SIGNAL_FUNC(CloseRequest), NULL);

  gtk_widget_show(window);
  gtk_main
