Qt之QGridLayout布局简单应用

实现A、B、C布局；

结构如图：

关键代码如下：

 MainWindow::MainWindow(QWidget *parent) :

     QWidget(parent)

 {

         this->setGeometry(QRect(0,0,1000,800));

         QGridLayout *gridLayout = new QGridLayout;

         QWidget *widget1 = new QWidget();

         QPushButton *A = new QPushButton("A",widget1);

         A->setGeometry(QRect(100,100,100,60));

         QWidget *widget2 = new QWidget();

         QPushButton *B = new QPushButton("B",widget2);

         B->setGeometry(QRect(100,100,100,60));

         QWidget *widget3 = new QWidget();

         QPushButton *C = new QPushButton("C",widget3);

         C->setGeometry(QRect(0,10,100,30));

         widget1->setMaximumWidth(300);

         widget1->setMinimumWidth(300);

         widget3->setMaximumHeight(40);

         widget3->setMaximumHeight(40);

         gridLayout->setMargin(0);

         int vW = width()/300;

         int vh = height()/60;

         qDebug() << vW << vh;

         gridLayout->addWidget(widget1, 0,0,5,1);

         gridLayout->addWidget(widget2, 0,1,5-1,5-1);

         gridLayout->addWidget(widget3, 5-1,1,1,5-1);

         gridLayout->setSpacing(1);

         QStringList qss;

         qss.append("QWidget{border:1px solid #000000;background:#DC2520}");

         this->setStyleSheet(qss.join(""));

         setLayout(gridLayout);

 }
