用这个没有用，为什么还是图1的效果啊？

Question

void network::InitConBox(){QGridLayout *layout = new QGridLayout();layout->setColumnMinimumWidth(0,71);layout->setColumnMinimumWidth(1, 111);layout->setColumnMinimumWidth(2, 75);layout->setColumnMinimumWidth(3, 90);layout->setColumnMinimumWidth(4, 141);layout->setColumnMinimumWidth(5, 115);//控件按两行七列排列layout->addWidget(ui.label1, 0, 0,Qt::AlignRight);layout->addWidget(ui.label2, 1, 0,Qt::AlignRight);layout->addWidget(ui.label3, 0, 3,Qt::AlignRight);layout->addWidget(ui.label4, 1, 3,Qt::AlignRight);layout->addWidget(ui.tx_IpAddr,0, 1);layout->addWidget(ui.Bn_Connect,0, 2);layout-> addWidget(ui.lbstatus,1,1, 1,2);layout->addWidget(ui.comSel,0, 4,Qt::AlignLeft);layout->addWidget(ui.edit_mac,1,4);layout->addWidget(ui.bn_Closeconnect,0,5,Qt::AlignLeft); //IP地址设置按钮layout->addWidget(ui.Bn_GetMac,1,5,Qt::AlignLeft); //GET MAC按钮layout->addWidget(ui.BnLearnStaatu,0,6,2,1,Qt::AlignVCenter); //开启学习按钮layout->setRowStretch(0, 10);layout->setRowStretch(1, 10);layout->setColumnStretch(0,0);layout->setColumnStretch(1, 5);layout->setColumnStretch(2,2);layout->setColumnStretch(3, 0);layout->setColumnStretch(4, 5);layout->setColumnStretch(5,2);layout->setColumnStretch(6,2);layout->setSpacing (10);ui.groupBox1->setLayout(layout);}开启学习按钮我想占两行要怎么实现啊？（效果如图）layout->addWidget(ui.BnLearnStaatu,0,6,2,1,Qt::AlignVCenter);这样显示还是占一行，请高手帮帮忙啊！layout->addWidget(ui.BnLearnStaatu,0,6,2,1,Qt::AlignVCenter);

Answer 1

void QGridLayout::addLayout ( QLayout * layout, int row, int column, int rowSpan, int columnSpan, Qt::Alignment alignment = 0 )
addWidget这个函数有四个int型的参数，row是所在行，column是所在列，rowSpan是行跨度，你想跨两行这个地方设置2，columnSpan这个是列跨度。

Answer 2

用这个函数添加控件
void QGridLayout::addWidget ( QWidget * widget, int fromRow, int fromColumn, int rowSpan, int columnSpan, Qt::Alignment alignment = 0 )
This is an overloaded function.
This version adds the given widget to the cell grid, spanning multiple rows/columns. The cell will start at fromRow, fromColumn spanning rowSpan rows and columnSpan columns. The widget will have the given alignment.
If rowSpan and/or columnSpan is -1, then the widget will extend to the bottom and/or right edge, respectively.
