11.QT窗口布局切割

 int main(int argc, char *argv[])
 {
     QApplication a(argc, argv);
     //MainWindow w;
     //w.show();
     //左右分割
 7     QSplitter *spmain = new QSplitter(Qt::Horizontal,0);
 8     QTextEdit *textleft = new QTextEdit("left",spmain);
 9     textleft->setAlignment(Qt::AlignCenter);
10
11     //设置位置,spmain的左边
12     QSplitter *spright = new QSplitter(Qt::Vertical,spmain);
13     QTextEdit *textup = new QTextEdit("right up",spright);
14     textup->setAlignment(Qt::AlignCenter);
15
16     QTextEdit *textdown = new QTextEdit("right down",spright);
17     textleft->setAlignment(Qt::AlignCenter);

     spmain->show();
     return a.exec();
 }
