GObject 参考手册:教程:如何创建和使用信号

Simple use of signals

The most basic use of signals is to implement simple event notification: for example, if we have a MamanFile object, and if this object has a write method, we might wish to be notified whenever someone uses this method. The code below shows how the user can connect a callback to the write signal. Full code for this simple example is located in sample/signal/maman-file.{h|c} and in sample/signal/test.c

GObject 参考手册:教程:如何定义和实现接口

How to define interfaces

The bulk of interface definition has already been shown in the section called “Non-instantiable classed types: interfaces” but I feel it is needed to show exactly how to create an interface. The sample source code associated to this section can be found in the documentation’s source tarball, in the sample/interface/maman-ibaz.{h|c} file.

GObject 参考手册:教程:如何定义和实现在一个新 GObject

Clearly, this is one of the most common questions people ask: they just want to crank code and implement a subclass of a GObject. Sometimes because they want to create their own class hierarchy, sometimes because they want to subclass one of GTK+’s widget. This chapter will focus on the implementation of a subtype of GObject. The sample source code associated with this section can be found in the documentation’s source tarball, in the sample/gobject directory:

GObject 参考手册:概念:GObject 消息系统:信号

GObject’s signals have nothing to do with standard UNIX signals: they connect arbitrary application-specific events with any number of listeners. For example, in GTK+, every user event (keystroke or mouse move) is received from the X server and generates a GTK+ event under the form of a signal emission on a given object instance.

GObject 参考手册:概念:GObject 消息系统

Closures are central to the concept of asynchronous signal delivery which is widely used throughout GTK+ and GNOME applications. A closure is an abstraction, a generic representation of a callback. It is a small structure which contains three objects:
