这段代码是基于 Qt 框架开发的一个对话框界面,下面是每行代码的详细注释:
```cpp
verticalLayout->addWidget(groupBox_2);
```
创建一个 QVBoxLayout 布局,并将 groupBox_2 加入该布局中。
```cpp
groupBox = new QGroupBox(QWDialog);
groupBox->setObjectName(QString::fromUtf8("groupBox"));
```
创建一个名为 groupBox 的 QGroupBox,并将其加入对话框界面。
```cpp
horizontalLayout_3 = new QHBoxLayout(groupBox);
```
创建一个 QHBoxLayout 布局,并将其加入到 groupBox 中。
```cpp
horizontalLayout_3->setSpacing(6);
horizontalLayout_3->setContentsMargins(11, 11, 11, 11);
horizontalLayout_3->setObjectName(QString::fromUtf8("horizontalLayout_3"));
```
设置该 QHBoxLayout 布局的间距为 6,边距为 11,11,11,11,并设置其对象名为 "horizontalLayout_3"。
```cpp
rBtnBlack = new QRadioButton(groupBox);
rBtnBlack->setObjectName(QString::fromUtf8("rBtnBlack"));
rBtnBlack->setChecked(true);
horizontalLayout_3->addWidget(rBtnBlack);
```
创建一个 QRadioButton 控件,并将其加入到 QHBoxLayout 布局中,并将其对象名设置为 "rBtnBlack",并设置其为默认选中。
```cpp
rBtnRed = new QRadioButton(groupBox);
rBtnRed->setObjectName(QString::fromUtf8("rBtnRed"));
horizontalLayout_3->addWidget(rBtnRed);
```
创建一个 QRadioButton 控件,并将其加入到 QHBoxLayout 布局中,并将其对象名设置为 "rBtnRed"。
```cpp
rBtnBlue = new QRadioButton(groupBox);
rBtnBlue->setObjectName(QString::fromUtf8("rBtnBlue"));
horizontalLayout_3->addWidget(rBtnBlue);
```
创建一个 QRadioButton 控件,并将其加入到 QHBoxLayout 布局中,并将其对象名设置为 "rBtnBlue"。
```cpp
verticalLayout->addWidget(groupBox);
```
将 groupBox 加入到 QVBoxLayout 布局中。
```cpp
txtEdit = new QPlainTextEdit(QWDialog);
txtEdit->setObjectName(QString::fromUtf8("txtEdit"));
QFont font1;
font1.setPointSize(20);
txtEdit->setFont(font1);
verticalLayout->addWidget(txtEdit);
```
创建一个 QPlainTextEdit 控件,并将其加入到 QVBoxLayout 布局中,并将其对象名设置为 "txtEdit",并设置其字体大小为 20。
```cpp
verticalSpacer = new QSpacerItem(20, 40, QSizePolicy::Minimum, QSizePolicy::Expanding);
verticalLayout->addItem(verticalSpacer);
```
创建一个垂直方向上的空白控件,并将其加入到 QVBoxLayout 布局中。
```cpp
horizontalLayout = new QHBoxLayout();
horizontalLayout->setSpacing(6);
horizontalLayout->setObjectName(QString::fromUtf8("horizontalLayout"));
```
创建一个 QHBoxLayout 布局,并将其对象名设置为 "horizontalLayout"。
```cpp
horizontalSpacer_2 = new QSpacerItem(40, 20, QSizePolicy::Expanding, QSizePolicy::Minimum);
horizontalLayout->addItem(horizontalSpacer_2);
```
创建一个水平方向上的空白控件,并将其加入到 QHBoxLayout 布局中。
```cpp
btnOK = new QPushButton(QWDialog);
btnOK->setObjectName(QString::fromUtf8("btnOK"));
horizontalLayout->addWidget(btnOK);
```
创建一个 QPushButton 控件,并将其加入到 QHBoxLayout 布局中,并将其对象名设置为 "btnOK"。
```cpp
btnCancel = new QPushButton(QWDialog);
btnCancel->setObjectName(QString::fromUtf8("btnCancel"));
horizontalLayout->addWidget(btnCancel);
```
创建一个 QPushButton 控件,并将其加入到 QHBoxLayout 布局中,并将其对象名设置为 "btnCancel"。
```cpp
horizontalSpacer = new QSpacerItem(40, 20, QSizePolicy::Expanding, QSizePolicy::Minimum);
horizontalLayout->addItem(horizontalSpacer);
```
创建一个水平方向上的空白控件,并将其加入到 QHBoxLayout 布局中。
```cpp
btnClose = new QPushButton(QWDialog);
btnClose->setObjectName(QString::fromUtf8("btnClose"));
horizontalLayout->addWidget(btnClose);
```
创建一个 QPushButton 控件,并将其加入到 QHBoxLayout 布局中,并将其对象名设置为 "btnClose"。
```cpp
verticalLayout->addLayout(horizontalLayout);
```
将 QHBoxLayout 布局加入到 QVBoxLayout 布局中。
```cpp
retranslateUi(QWDialog);
```
重新翻译对话框界面。
```cpp
QObject::connect(btnOK, SIGNAL(clicked()), QWDialog, SLOT(accept()));
QObject::connect(btnCancel, SIGNAL(clicked()), QWDialog, SLOT(reject()));
QObject::connect(btnClose, SIGNAL(clicked()), QWDialog, SLOT(close()));
QMetaObject::connectSlotsByName(QWDialog);
```
分别将 btnOK、btnCancel、btnClose 按钮的 clicked 信号连接到 QWDialog 的 accept、reject、close 槽函数,并通过 QMetaObject::connectSlotsByName() 函数连接界面中的所有对象的信号与槽。
