QT程序在Windows下的开发主要基于Qt库，这是一个跨平台的应用程序开发框架，广泛应用于桌面、移动设备和嵌入式系统。在本例中，我们关注的是Qt 4.5.0版本，这是一个较早但仍然具有重要历史价值的版本。 Qt 4.5.0在2009年发布，它引入了许多新特性和改进，包括QML（Qt Meta Language）的初步支持，这是用于创建富用户界面的声明性语言，以及对QtWebKit的增强，允许在Qt应用程序中嵌入Web内容。此外，4.5版本还加强了Qt网络模块，提高了性能，并提供了更好的多线程支持。在Windows平台上开发Qt程序，开发者通常需要安装Qt SDK，它包含Qt库、开发工具（如Qt Creator IDE）、文档和示例代码。对于Qt 4.5.0，开发者可能需要下载并安装相应版本的SDK，然后使用IDE来编写、构建和调试代码。描述中提到的"一个简单的应用窗口程序"，在Qt中通常会使用`QWidget`类作为基础，创建一个基本的窗口。`QMainWindow`则是一个更复杂的窗口类，它提供了菜单栏、工具栏和其他窗口部件的支持。菜单可以通过`QMenuBar`和`QMenu`创建，而工具栏则由`QToolBar`类实现。这些元素都是Qt的图形用户界面（GUI）组件，可以方便地进行拖放设计或通过代码动态创建。在实际编程中，开发者会使用C++语言，结合Qt的API来实现功能。例如，创建一个菜单项，可以这样写： ```cpp QAction *action = new QAction("Exit", this); connect(action, SIGNAL(triggered()), qApp, SLOT(quit())); QMenu *menu = menuBar()->addMenu("File"); menu->addAction(action); ``` 这段代码首先创建了一个动作（Action），当触发这个动作时，会调用应用程序的退出函数。然后，我们在菜单栏中添加了一个名为“File”的菜单，并将这个动作添加到该菜单中。至于"工具栏"，同样可以通过添加动作并将其添加到工具栏上来实现： ```cpp QToolBar *toolbar = addToolBar("Tools"); toolbar->addAction(action); ``` 这里的`addToolBar`函数创建了一个新的工具栏，并使用`addAction`将之前创建的退出动作添加到工具栏上。文件名列表中提到的"application"可能是项目中的主应用程序文件，通常以`.pro`扩展名，这是一个项目配置文件，包含了编译和链接设置，以及项目依赖的Qt模块。开发者可以使用`qmake`工具根据`.pro`文件生成Makefile，然后使用编译器（如Visual Studio的编译器）来构建和运行程序。总结起来，使用Qt 4.5.0在Windows下开发应用程序涉及安装Qt SDK，利用Qt Creator或类似IDE进行GUI设计，使用C++和Qt API编写代码，以及通过`.pro`文件管理项目。此过程涉及到的知识点包括Qt库的结构、窗口部件的创建和交互、事件处理、信号与槽机制以及项目构建流程。尽管现在Qt已经更新到了更高级的版本，但对于学习Qt的基础知识，理解4.5.0版本的机制仍然是有价值的。
