# Qt 5.15 界面开发核心知识
|
||||
|
||||
## QSS样式表精通
|
||||
|
||||
### 基础语法结构
|
||||
```css
|
||||
/* 选择器语法 */
|
||||
QWidget { background-color: #f0f0f0; }
|
||||
QPushButton#myButton { color: blue; }
|
||||
QLabel[class="title"] { font-size: 18px; }
|
||||
|
||||
/* 伪状态选择器 */
|
||||
QPushButton:hover { background-color: #e0e0e0; }
|
||||
QPushButton:pressed { background-color: #d0d0d0; }
|
||||
QPushButton:disabled { color: gray; }
|
||||
```
|
||||
|
||||
### 现代化按钮样式
|
||||
```css
|
||||
QPushButton {
|
||||
background-color: #4CAF50;
|
||||
border: none;
|
||||
color: white;
|
||||
padding: 8px 16px;
|
||||
border-radius: 4px;
|
||||
font-size: 14px;
|
||||
font-weight: bold;
|
||||
}
|
||||
|
||||
QPushButton:hover {
|
||||
background-color: #45a049;
|
||||
}
|
||||
|
||||
QPushButton:pressed {
|
||||
background-color: #3d8b40;
|
||||
}
|
||||
```
|
||||
|
||||
### 输入框美化
|
||||
```css
|
||||
QLineEdit {
|
||||
border: 2px solid #ddd;
|
||||
border-radius: 6px;
|
||||
padding: 8px;
|
||||
font-size: 14px;
|
||||
background-color: white;
|
||||
}
|
||||
|
||||
QLineEdit:focus {
|
||||
border-color: #4CAF50;
|
||||
outline: none;
|
||||
}
|
||||
```
|
||||
|
||||
## 布局管理器精通
|
||||
|
||||
### QVBoxLayout 垂直布局
|
||||
```cpp
|
||||
QVBoxLayout *layout = new QVBoxLayout;
|
||||
layout->addWidget(titleLabel);
|
||||
layout->addSpacing(10); // 添加间距
|
||||
layout->addWidget(contentWidget);
|
||||
layout->addStretch(); // 添加弹性空间
|
||||
layout->setContentsMargins(20, 20, 20, 20); // 设置边距
|
||||
```
|
||||
|
||||
### QGridLayout 网格布局
|
||||
```cpp
|
||||
QGridLayout *gridLayout = new QGridLayout;
|
||||
gridLayout->addWidget(label1, 0, 0);
|
||||
gridLayout->addWidget(lineEdit1, 0, 1);
|
||||
gridLayout->addWidget(label2, 1, 0);
|
||||
gridLayout->addWidget(lineEdit2, 1, 1);
|
||||
gridLayout->setColumnStretch(1, 1); // 第二列可拉伸
|
||||
```
|
||||
|
||||
### QHBoxLayout 水平布局
|
||||
```cpp
|
||||
QHBoxLayout *buttonLayout = new QHBoxLayout;
|
||||
buttonLayout->addStretch();
|
||||
buttonLayout->addWidget(okButton);
|
||||
buttonLayout->addWidget(cancelButton);
|
||||
```
|
||||
|
||||
## 控件美化技巧
|
||||
|
||||
### QTableWidget 表格美化
|
||||
```css
|
||||
QTableWidget {
|
||||
gridline-color: #e0e0e0;
|
||||
background-color: white;
|
||||
alternate-background-color: #f9f9f9;
|
||||
}
|
||||
|
||||
QTableWidget::item {
|
||||
padding: 8px;
|
||||
border: none;
|
||||
}
|
||||
|
||||
QTableWidget::item:selected {
|
||||
background-color: #4CAF50;
|
||||
color: white;
|
||||
}
|
||||
|
||||
QHeaderView::section {
|
||||
background-color: #f5f5f5;
|
||||
padding: 8px;
|
||||
border: 1px solid #ddd;
|
||||
font-weight: bold;
|
||||
}
|
||||
```
|
||||
|
||||
### QComboBox 下拉框美化
|
||||
```css
|
||||
QComboBox {
|
||||
border: 2px solid #ddd;
|
||||
border-radius: 6px;
|
||||
padding: 6px;
|
||||
min-width: 120px;
|
||||
}
|
||||
|
||||
QComboBox::drop-down {
|
||||
border: none;
|
||||
width: 20px;
|
||||
}
|
||||
|
||||
QComboBox::down-arrow {
|
||||
image: url(:/icons/down-arrow.png);
|
||||
width: 12px;
|
||||
height: 12px;
|
||||
}
|
||||
```
|
||||
|
||||
## 自定义控件开发
|
||||
|
||||
### 自定义按钮类
|
||||
```cpp
|
||||
class CustomButton : public QPushButton {
|
||||
Q_OBJECT
|
||||
public:
|
||||
CustomButton(const QString &text, QWidget *parent = nullptr);
|
||||
|
||||
protected:
|
||||
void paintEvent(QPaintEvent *event) override;
|
||||
void enterEvent(QEvent *event) override;
|
||||
void leaveEvent(QEvent *event) override;
|
||||
|
||||
private:
|
||||
bool m_hovered;
|
||||
QPropertyAnimation *m_animation;
|
||||
};
|
||||
```
|
||||
|
||||
### 渐变背景实现
|
||||
```cpp
|
||||
void CustomWidget::paintEvent(QPaintEvent *event) {
|
||||
QPainter painter(this);
|
||||
painter.setRenderHint(QPainter::Antialiasing);
|
||||
|
||||
QLinearGradient gradient(0, 0, 0, height());
|
||||
gradient.setColorAt(0, QColor(240, 240, 240));
|
||||
gradient.setColorAt(1, QColor(220, 220, 220));
|
||||
|
||||
painter.fillRect(rect(), gradient);
|
||||
}
|
||||
```
|
||||
|
||||
## 信号槽机制优化
|
||||
|
||||
### Lambda表达式连接
|
||||
```cpp
|
||||
connect(button, &QPushButton::clicked, [this]() {
|
||||
// 处理点击事件
|
||||
updateUI();
|
||||
});
|
||||
```
|
||||
|
||||
### 自定义信号定义
|
||||
```cpp
|
||||
class CustomWidget : public QWidget {
|
||||
Q_OBJECT
|
||||
signals:
|
||||
void dataChanged(const QString &data);
|
||||
void statusUpdated(int status);
|
||||
|
||||
public slots:
|
||||
void onDataReceived(const QByteArray &data);
|
||||
void onStatusChanged(bool connected);
|
||||
};
|
||||
```
|
||||
|
||||
## 性能优化技巧
|
||||
|
||||
### 减少重绘次数
|
||||
```cpp
|
||||
// 批量更新时禁用重绘
|
||||
widget->setUpdatesEnabled(false);
|
||||
// 执行多个更新操作
|
||||
widget->setUpdatesEnabled(true);
|
||||
widget->update(); // 手动触发重绘
|
||||
```
|
||||
|
||||
### 使用样式表缓存
|
||||
```cpp
|
||||
// 在类初始化时设置样式表，避免重复设置
|
||||
static const QString buttonStyle =
|
||||
"QPushButton { background-color: #4CAF50; }";
|
||||
button->setStyleSheet(buttonStyle);
|
||||
```
|
||||
|
||||
## 响应式设计
|
||||
|
||||
### 自适应布局
|
||||
```cpp
|
||||
void MainWindow::resizeEvent(QResizeEvent *event) {
|
||||
QMainWindow::resizeEvent(event);
|
||||
|
||||
// 根据窗口大小调整布局
|
||||
if (width() < 800) {
|
||||
// 小屏幕布局
|
||||
switchToCompactLayout();
|
||||
} else {
|
||||
// 大屏幕布局
|
||||
switchToNormalLayout();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### DPI适配
|
||||
```cpp
|
||||
// 获取系统DPI缩放比例
|
||||
qreal dpiScale = qApp->devicePixelRatio();
|
||||
int scaledSize = static_cast<int>(16 * dpiScale);
|
||||
font.setPixelSize(scaledSize);
|
||||
```
|
||||
|
||||
## 国际化支持
|
||||
|
||||
### 文本国际化
|
||||
```cpp
|
||||
// 在代码中使用tr()函数
|
||||
button->setText(tr("确定"));
|
||||
label->setText(tr("用户名："));
|
||||
|
||||
// 在.pro文件中添加
|
||||
TRANSLATIONS += app_zh_CN.ts app_en_US.ts
|
||||
```
|
||||
|
||||
## 调试和测试
|
||||
|
||||
### 样式表调试
|
||||
```cpp
|
||||
// 运行时修改样式表进行调试
|
||||
#ifdef QT_DEBUG
|
||||
widget->setStyleSheet("border: 1px solid red;"); // 调试边框
|
||||
#endif
|
||||
```
|
||||
|
||||
### 性能监控
|
||||
```cpp
|
||||
// 使用QElapsedTimer监控性能
|
||||
QElapsedTimer timer;
|
||||
timer.start();
|
||||
// 执行耗时操作
|
||||
qDebug() << "操作耗时：" << timer.elapsed() << "ms";
|
||||
```
