QT对话框去掉帮助和关闭按钮

转载自 http://blog.csdn.net/liqunzheng/article/details/7409657

建了一个对话框，我不想把边框去掉，只想去掉关闭按钮，
setWindowFlags(windowFlags()&~Qt::WindowCloseButtonHint&~Qt::WindowContextHelpButtonHint);
结果那个问号的按钮去掉了，但是关闭按钮还在，求助啊

setWindowFlags(Qt::WindowTitleHint | Qt::CustomizeWindowHint | Qt::WindowMinimizeButtonHint | Qt::WindowMaximizeButtonHint);
这样就行了，哈哈！
 

setWindowFlags(Qt::CustomizeWindowHint | Qt::WindowMinimizeButtonHint | Qt::WindowMaximizeButtonHint);
还是简单点好！
