楼上的兄弟 这样做我试了虽然是扁平的风格，但是点击按钮后还是会显示出它的边框啊
我现在考虑用label做 但是焦点没有映射在label里 而在label外的窗体 有高手能帮忙给看看吗

你可以自己写一个类，继承QLabel类，然后在这个类里重写mousePressEvent(QMouseEvent * e)这个函数，下面是我的程序里重写mousePressEvent(QMouseEvent * e)的一段，在单击label时弹出一个对话框。
void PixLabel::mousePressEvent(QMouseEvent * e){
QDialog *dlg = new QDialog( this, "dlg", true );
dlg->show();
QLabel::mousePressEvent(e);
}
