老规矩先上图
16进制转RGB RGB转16进制 屏幕颜色提取 功能概述颜色码转换和屏幕颜色提取 颜色码转换功能 输入支持输入RGB颜色代码或16进制颜色代码。输出转换为另一种格式的颜色代码。操作支持从RGB转换为16进制和反之转换。 屏幕颜色提取功能 操作捕获屏幕上鼠标位置的颜色信息。展示显示提取到的颜色包括16进制颜色代码和颜色预览。交互启动功能后可以在屏幕上移动鼠标以实时获取不同位置的颜色。终止点击特定键盘按键例如按下Tab键以停止捕获。
需求概述 颜色码转换功能 用户友好提供清晰的界面支持输入RGB或16进制颜色代码。格式转换允许用户在RGB和16进制颜色代码之间进行转换。展示结果将转换后的颜色代码显示给用户。 屏幕颜色提取功能 启动捕获点击按钮启动颜色捕获功能。显示颜色在界面上显示捕获到的颜色代码和颜色预览。实时更新随着鼠标移动实时显示不同位置的颜色。停止捕获通过特定操作例如按下Tab键停止捕获颜色。异常处理处理未找到屏幕或捕获颜色失败的情况。
这样的功能旨在提供一个便捷的界面允许用户在RGB和16进制颜色代码之间自由转换并且能够在屏幕上捕获颜色以获取准确的颜色信息。 核心代码实现

};核心代码讲解
让我们逐段解析 ColorConverter 类的代码。
class ColorConverter : public QWidget {
Q_OBJECT
public:explicit ColorConverter(QWidget *parent nullptr) : QWidget(parent) {// 在构造函数中初始化定时器colorTimer new QTimer(this);colorTimer-setInterval(100); // 设置定时器间隔为100毫秒connect(colorTimer, QTimer::timeout, this, ColorConverter::extractScreenColor);auto *layout new QVBoxLayout(this);// 创建颜色值转换部分的输入框和按钮colorInput new QLineEdit(this);layout-addWidget(colorInput);// ...略installEventFilter(this); // 安装事件过滤器以捕获鼠标事件}// ...略
};构造函数与定时器初始化构造函数中创建了一个 ColorConverter 对象并初始化了一个定时器 colorTimer。这个定时器用于每 100 毫秒触发一次屏幕颜色提取功能并与 extractScreenColor 函数连接。 界面布局初始化在构造函数中使用了垂直布局管理器 QVBoxLayout并添加了颜色输入框到布局中。 事件过滤器安装installEventFilter(this) 安装了一个事件过滤器来监视该对象所接收到的事件。在这个场景中它用于捕获鼠标事件以停止颜色提取。
转换函数
void convertToHexColor() {// 获取输入框中的颜色值转换为16进制// ...
}void convertToRgbColor() {// 获取输入框中的颜色值转换为RGB格式// ...
}QLineEdit 和 QTextEdit分别用于输入和显示颜色值convertToHexColor 和 convertToRgbColor 函数用于颜色转换。
屏幕颜色提取器
void startColorCapture() {// 开始捕获颜色的槽函数// ...
}void extractScreenColor() {// 提取屏幕颜色的槽函数// ...
}void stopColorCapture() {// 停止颜色捕获的槽函数// ...
}QPushButton 和 QLabelextractColorButton 用于启动颜色捕获screenColorOutput 和 screenColorBlock 用于显示屏幕颜色信息。
事件过滤器
bool eventFilter(QObject *watched, QEvent *event) override {// 事件过滤器捕获键盘事件以终止颜色捕获// ...
}QObject 和 QEventeventFilter 捕获键盘事件当用户按下 Tab 键松开时终止颜色捕获。
总结
主要利用了 Qt 中的 QWidget、QObject、QTimer、QLineEdit、QPushButton、QTextEdit、QLabel 等部件以及事件过滤器功能来实现颜色转换和屏幕颜色提取的功能。按钮的点击触发不同的槽函数展示了转换后的颜色信息或从屏幕获取的颜色信息。同时通过事件过滤器监听键盘事件以实现终止屏幕颜色提取的功能。 讲解完毕下面是完整代码复制到本地跑一跑吧~
