如何在菜单栏上创建关闭按钮？

Question

在下图中，红色矩形是菜单栏。我想创建绿色矩形所在的关闭按钮，但我不知道该怎么做。有什么建议？我想让UI看起来像Adobe Photoshop CS6？

Answer 1

QMenuBar小部件有一个方法＆＃34; setCornerWidget＆＃34;，你可以这样做：

    // Hiden Window Title
    setWindowFlags(Qt::FramelessWindowHint);

    // Set widget on the top left corner
    QPushButton* menuTopRightButton = new QPushButton("TL", m_menubar);
    m_menubar->setCornerWidget(menuTopRightButton, Qt::TopLeftCorner);

    // Set widget on the top right corner
    QPushButton* menuTopLeftButton = new QPushButton("TR", m_menubar);
    m_menubar->setCornerWidget(menuTopRightButton, Qt::TopRightCorner);

Answer 2

#closeButton {
position: absolute;
height:20px;
width:100px;
background:red;
float:right;
position:absolute;
right:0px;
top:0px;
}
