我是C ++和Qt 5.2.1的新手。我实际上正在学习如何使用Qt。为了尽可能简单,我正在使用Qt Creator 3.0.1。
我已经在项目的main.cpp文件中编写了这小段代码:
#include <QApplication>
#include <QPushButton>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QPushButton bouton("Hello !");
bouton.show();
return app.exec();
}

和.pro文件(默认情况下):
SOURCES += \
main.cpp

我试图使其运行,然后出现问题“ QApplication:没有这样的文件或目录”。
然后,我在.pro文件(完整文件)中添加了“ QT + =小部件”:
SOURCES += \
main.cpp
QT += widgets

现在我得到:
Starting <path to .exe>...
The program has unexpectedly finished.
<path to .exe> crashed

请告诉我如何使它工作。感谢您的阅读和帮助。
