1.1从Hello Qt开始
差不多所有的程序教材都从Hello 开始,下面就是这个程序的qt版本。
1 #include <QApplication>
2 #include <QLabel>
3 int main(int argc, char *argv[])
4 {
5 QApplication app(argc, argv);
6 QLabel *label = new QLabel("Hello Qt!");
7 label->show();
8 return app.exec();
9 }

从智能天线的工作原理出发说明使用智能天线时很难实现小区的分扇区应用、多频点天线公
用,因此可以证明智能天线还不是一项可供商用的实用技术 考虑相邻小区/扇区时隙的不对称分
配所产生的相邻小区/扇区收发干扰时,可以证明上、下行时隙实质上是不能按需分配的。3 G使
用的频段是2 GHz,具有传播衰落大、穿透能力差、不易做大范围覆盖。TD2SCDMA标准很难提供3
G标准所规定的在车载、步行、静止环境下分别达到144 kbit/ s、384 kbit/ s和2 048 kbit/ s的无线接
入速率要求。-It is p resented in the paper that it is difficult to realize the sectored cell and the same antenna for
multip le frequency channels by analyzing the theory of the smart antenna. Therefore it can be p roved that the smart
antenna technology is not a commercial technology at p resent. Asymmetry slot distribution between inter2cells/ sec2
torswould bring the transmission and receiving interference between the inter2cells/ sectors, so it can’t be put into
p ractical app lication. The technological defects of the TD2SCDMA standard are analyzed in the paper from many as2
pects, such as the characteristics of 2 GHz frequency band,MS’s transmission power, a cell capacity on up link /
downlink and so on. TD2SCDMA system is difficult to support different radio access data rates, such as vehicular
environment: 144 kbit/ s, pedestrian environment: 384 kbit/ s, indoor office environment: 2. 048 Mbit/ s, which
are required by 3G standards

一般我们使用的框架是VC提供的Wizard生成的MFC App Wizard(exe)框架,无论是多文档还是单文档,都存在指针获取和操作 问题。
下面这节内容主要是一般的框架,然后再讲多线程中的指针使用。使用到的类需要包含响应的头文件。 首先一般获得本类(视,文档,对话框都支持)实例指针 this,用this的目的,主要可以通过类中的函数向其他类或者函数中发指针,以便于在非本类中操作和使用本类中的功能。 这其中的关键在于理解 m_pMainWnd, AfxGetApp(),AfxGetMainWnd() 的意义!
-General framework we are using the MFC App Wizard (exe) provides the framework Wizard VC generated, whether it is a single document or multiple documents, there are pointers to access and operational problems. The following section is primarily aimed at the general frame, and then repeat that multiple threads using a pointer. Use the class needs to contain the response headers. First, get this general class (depending on the document, dialog support) instance pointer this, with this purpose, the main pointer can be made through the class of functions to other classes or functions in order to operate in this class and use non this class features. Which is the key to understanding m_pMainWnd, AfxGetApp (), AfxGetMainWnd () meaning!
