- 垂直布局：QVBoxLayout
先來一兩代碼：
QWidget *widget = new QWidget();
QVBoxLayout * vBoxLayout = new QVBoxLayout();
QLabel *label = new QLabel("hello");
QPushButton *pushButton = new QPushButton("hi");
vBoxLayout->addWidget(label);
vBoxLayout->addWidget(pushButton);
widget->setLayout(vBoxLayout);
widget->show();
效果：
QVBoxLayout
- 水平布局：QHBoxLayout
一樣：
QWidget *widget = new QWidget();
QHBoxLayout * hBoxLayout = new QHBoxLayout();
QLabel *label = new QLabel("hello");
QPushButton *pushButton = new QPushButton("hi");
hBoxLayout->addWidget(label);
hBoxLayout->addWidget(pushButton);
widget->setLayout(hBoxLayout);
widget->show();
QHBoxLayout
- QHBoxLayout嵌套QVBoxLayout
QWidget *widget = new QWidget();
QHBoxLayout * hBoxLayout = new QHBoxLayout();
QVBoxLayout * vBoxLayout = new QVBoxLayout();
QLabel *label_text = new QLabel("Chengdu 1 – 3 Day Weather Forecast Summary");
QLabel *label_picture = new QLabel();
label_picture->setPixmap(QPixmap(":/weather").scaled(32,32, Qt::KeepAspectRatioByExpanding));
QPushButton *pushButton = new QPushButton("more");
vBoxLayout->addWidget(label_text);
vBoxLayout->addWidget(pushButton);
hBoxLayout->addWidget(label_picture);
hBoxLayout->addLayout(vBoxLayout);
widget->setLayout(hBoxLayout);
widget->show();
QHBoxLayout嵌套QVBoxLayout
- 總結(jié)
1.向布局添加一個Widget:
void QBoxLayout::addWidget(QWidget *widget, int stretch = 0, Qt::Alignment alignment = Qt::Alignment())
2.向布局再添加一個布局
void QBoxLayout::addLayout(QLayout *layout, int stretch = 0)?
3.最后重归，使用它來確定Widget的布局
void QWidget::setLayout(QLayout *layout)
