QHBoxLayout *hbox1 = new QHBoxLayout();
//hbox1->addWidget....
QHBoxLayout *hbox2 = new QHBoxLayout();
//......
QHBoxLayout *hbox3= new QHBoxLayout();
//....
QVBoxLayout mainLayout = new QVBoxLayout();
mainLayout->addLayout(hbox1);
mainLayout->addLayout(hbox2);
mainLayout->addLayout(hbox3);
可是每次hbox3被hide()时, hbox1和hbox2就会向下移动.占用hbox3位置,
而当hbox3被show()时, hbox1和hbox2就会退出hbox3原来的位置...
我想当hbox3被hide()时, hbox1和hbox2所在位置不变..即不向下移动
.hbox3的位置只显示空白(即背景QWidget)
怎么现实???谢谢..........
