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();
