4.在main.cpp中修改**，改為如下**
#include
int main(int argc, char *argv)
5.按照 構建->qmake->run的順序進行執行，需要注意:執行的版本是release版本還是debug版本。
執行結果如下
6.對**的解釋如下
其中 (1)
qlabel *label = new qlabel("hello, world!");
label->show();
將應用程式的控制權移交給qt。這時，程式的事件迴圈就開始了，也就是說，這時可以響應你發出的各種事件了
7.qt支援html解析
講main.cpp的**改為如下形式
#include
int main(int argc, char *argv)
執行結果如下
8.在main.cpp中
main 函式不能缺少的兩行**是
#include
int main(int argc, char *argv)
