qt控件被遮住的问题

[jokers1990]

我在QDialog上定义了两个控件，一个QPushButton，一个QLabel，用setGeometry给它们设置好位置，然后我定义一个槽与QPushButton对象的click()信号连接，按一下QPushButton，将高度放大，然后发现它会被下面的QLabel遮住，除非将new QLabel 放在new QPushButton之前，请问下怎么解决这个问题啊？？？

class CMyDialog : public QDialog
{
    Q_OBJECT
public:
    CMyDialog(QWidget *parent);
private slots:
    void ResizeFun();
private:
    QPushButton *btn;
    QLabel *lab;
}

CMyDialog:CMyDialog(QWidget *parent)
    :QDialog(parent)
{
    btn = new QPushButton(this);
    lab = new QLabel(this);
    btn->setGeometry(0, 0, 100, 50);
    lab->setGeometry(0, 70, 100, 50);
    connect(btn, SIGNAL(clicked()), this, SLOT(ResizeFun()));
}

void CMyDialog::ResizeFun()
{
    btn->resize(btn->geometry().width(), btn->geometry(),height()*2);
}

打开QWidget的手册，看 stackUnder() , raise() ,lower()

[l4kangaxx]

Raises this widget to the top of the parent widget's stack. After this call the widget will be visually in front of any overlapping sibling widgets. Note: When using activateWindow(), you can call this function to ensure that the window is stacked on top. See also lower() and stackUnder(). 想显示谁就调用谁的raise
