Qt的布局

Qt的布局有四种：

1. 垂直布局：QVBoxLayout
2. 水平布局：QHBoxLayout
3. 网格布局：QGridLayout
4. 表单布局：QFormLayout

垂直布局

MainWindow::MainWindow(QWidget *parent)
    : QWidget(parent)
{
    QWidget *window = new QWidget(this);
    QPushButton *button1 = new QPushButton("One");
    QPushButton *button2 = new QPushButton("Two");
    QPushButton *button3 = new QPushButton("Three");
    QPushButton *button4 = new QPushButton("Four");
    QPushButton *button5 = new QPushButton("Five");

    QVBoxLayout *layout = new QVBoxLayout(window);
    layout->addWidget(button1);
    layout->addWidget(button2);
    layout->addWidget(button3);
    layout->addWidget(button4);
    layout->addWidget(button5);

    window->show();


}

    : QWidget(parent)
{
    QPushButton *button1 = new QPushButton("One");
    QPushButton *button2 = new QPushButton("Two");
    QPushButton *button3 = new QPushButton("Three");
    QPushButton *button4 = new QPushButton("Four");
    QPushButton *button5 = new QPushButton("Five");

    QVBoxLayout *layout = new QVBoxLayout(this);
    layout->addWidget(button1);
    layout->addWidget(button2);
    layout->addWidget(button3);
    layout->addWidget(button4);
    layout->addWidget(button5);

}

水平布局

QWidget *window = new QWidget(this);
    QPushButton *button1 = new QPushButton("One");
    QPushButton *button2 = new QPushButton("Two");
    QPushButton *button3 = new QPushButton("Three");
    QPushButton *button4 = new QPushButton("Four");
    QPushButton *button5 = new QPushButton("Five");

    QHBoxLayout *layout = new QHBoxLayout(window);
    layout->addWidget(button1);
    layout->addWidget(button2);
    layout->addWidget(button3);
    layout->addWidget(button4);
    layout->addWidget(button5);

    window->show();![请添加图片描述](https://img-blog.csdnimg.cn/bdcd846d326242d68875cd842f78bb84.png)

网格布局

 QWidget *window = new QWidget(this);
    QPushButton *button1 = new QPushButton("One");
    QPushButton *button2 = new QPushButton("Two");
    QPushButton *button3 = new QPushButton("Three");
    QPushButton *button4 = new QPushButton("Four");
    QPushButton *button5 = new QPushButton("Five");

    QGridLayout *layout = new QGridLayout(window);
    layout->addWidget(button1,0,0);
    layout->addWidget(button2,0,1);
    layout->addWidget(button3,1,0);
    layout->addWidget(button4,1,1);
    layout->addWidget(button5,2,0);

    window->show();

表单布局

    QFormLayout *formLayout = new QFormLayout;
    QLineEdit *nameLineEdit = new QLineEdit;
    QLineEdit *emailLineEdit = new QLineEdit;
    QSpinBox *ageSpinBox = new QSpinBox;
    formLayout->addRow(tr("&Name:"), nameLineEdit);
    formLayout->addRow(tr("&Email:"), emailLineEdit);
    formLayout->addRow(tr("&Age:"), ageSpinBox);
    setLayout(formLayout);
