GObject, Glib, GDK, GTK+...
原本只是打算学习怎么使用GTK+进行图形界面的开发，不过在看了tigersoldier写的控件之后，对GTK+的内部机制产生了强烈的好奇心，于是下载了源码来看。
结果，越看越迷糊，涉及到的内容好多:
GObject:
“GObject provides the object system used for Pango and GTK+.”
Glib:
"GLib provides the core application building blocks for libraries and applications written in C. It provides the core object system used in GNOME, the main loop implementation, and a large set of utility functions for strings and common data structures."
GDK:
"An intermediate layer which isolates GTK+ from the details of the windowing system."
GTK+
"GTK+ is the primary library used to construct user interfaces in GNOME applications. It provides user interface controls and signal callbacks to control user interfaces."
目标是彻底理解下面这段最简单的GTK+代码的工作原理及实现:
#include<gtk/gtk.h>
static gint delete_event(GtkWidget *widget, GdkEvent *event, gpointer data)
{
gtk_main_quit();
}
int main(int argc, char *argv[])
{
GtkWidget *window;
gtk_init(&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
g_signal_connect(G_OBJECT(window), "delete_event", G_CALLBACK(delete_event), NULL);
gtk_widget_show(window);
gtk_main();
return 0;
}
static gint delete_event(GtkWidget *widget, GdkEvent *event, gpointer data)
{
gtk_main_quit();
}
int main(int argc, char *argv[])
{
GtkWidget *window;
gtk_init(&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
g_signal_connect(G_OBJECT(window), "delete_event", G_CALLBACK(delete_event), NULL);
gtk_widget_show(window);
gtk_main();
return 0;
}
加油，加油...
