Qt实现Elementui警告的样式

　　这个是elemnt-ui的原先样式
　　这个是qt实现的基本样式
　　核心代码如下：
　　头文件#ifndef DTPOPUPWINDOW_H #define DTPOPUPWINDOW_H  #include  #include   namespace Ui { class DTPopupWindow; }  enum E_POPUP_TYPE {     E_WARNING = 0, // 警告弹窗     E_ERROR,  // 错误     E_INFO,   // 消息     E_SUCCESS, // 成功 };  class DTPopupWindow : public QWidget {     Q_OBJECT  public:     explicit DTPopupWindow(QWidget *parent = nullptr);     ~DTPopupWindow();      /******设置弹窗类型**********/     void setPopupType(const E_POPUP_TYPE& popupType)     {         m_popupType = popupType;     }      void setPopupText(const QString&);      void popupShow();  private slots:     void slotTimer(); private:     Ui::DTPopupWindow *ui;     E_POPUP_TYPE m_popupType = E_POPUP_TYPE::E_INFO;     QTimer* m_timer ; };  #endif // DTPOPUPWINDOW_H
　　实现部分：cpp#include ＂dtpopupwindow.h＂ #include ＂ui_dtpopupwindow.h＂ #include  #include   #define SUCCESS_BACKGROUND_COLOR QString(＂240, 249, 235＂) #define WARNING_BACKGROUND_COLOR QString(＂253, 246, 236＂) #define INFO_BACKGROUND_COLOR QString(＂244, 244, 245＂) #define ERROR_BACKGROUND_COLOR QString(＂254, 240, 240＂)  #define SUCCESS_FONT_COLOR QString(＂103, 194, 58＂) #define WARNING_FONT_COLOR QString(＂230, 162, 60＂) #define INFO_FONT_COLOR QString(＂205, 173, 153＂) #define ERROR_FONT_COLOR QString(＂247, 108, 108＂)  DTPopupWindow::DTPopupWindow(QWidget *parent) :     QWidget(parent),     ui(new Ui::DTPopupWindow) {     setWindowFlags(Qt::WindowStaysOnTopHint); // 置顶     setWindowFlag(Qt::FramelessWindowHint);    // setAttribute(Qt::WA_StyledBackground, true);    // setStyleSheet(＂background-color: rgb(61, 60, 64); font: 12px; color: #EAEAEA;＂);     ui->setupUi(this);     m_timer = new QTimer(this); //    timer->setSingleShot(true);//仅触发一次     connect(m_timer, SIGNAL(timeout()), this, SLOT(slotTimer())); }  DTPopupWindow::~DTPopupWindow() {     delete ui; }  void DTPopupWindow::setPopupText(const QString & qsText) {     ui->lbl_tip->setText(qsText); }  void DTPopupWindow::slotTimer() {     m_timer->stop();     this->hide(); }  void DTPopupWindow::popupShow() {     QDesktopWidget *deskTop=QApplication::desktop();     auto  deskRect=deskTop->availableGeometry();     QPoint normalPoint;     normalPoint.setX(deskRect.width()/2 - this->width() /2);     normalPoint.setY(20);     this->setGeometry(normalPoint.x(),normalPoint.y(),this->width(),this->height());     QString base_color = (＂QWidget { background-color: rgb(%1); font: 14px; color: rgb(%2) }＂);     switch (m_popupType) {     case E_POPUP_TYPE::E_SUCCESS:     {         QString qsBB = base_color.arg(SUCCESS_BACKGROUND_COLOR).arg(SUCCESS_FONT_COLOR);         this->setStyleSheet(base_color.arg(SUCCESS_BACKGROUND_COLOR).arg(SUCCESS_FONT_COLOR));         break;     }     case E_POPUP_TYPE::E_WARNING:     {         this->setStyleSheet(base_color.arg(WARNING_BACKGROUND_COLOR).arg(WARNING_FONT_COLOR));         break;     }     case E_POPUP_TYPE::E_INFO:     {         this->setStyleSheet(base_color.arg(INFO_BACKGROUND_COLOR).arg(INFO_FONT_COLOR));         break;     }     case E_POPUP_TYPE::E_ERROR:     {         this->setStyleSheet(base_color.arg(ERROR_BACKGROUND_COLOR).arg(ERROR_FONT_COLOR));         break;     }     default:         break;     }     this->show();     m_timer->start(6000); // 持续6秒 }

　　使用方式：DTPopupWindow popWindow;    popWindow.setPopupType(popType);     popWindow.setPopupText(qsInfo);    popWindow.popupShow();
　　目前该方法已经支持了警告、成功、提示和失败四种样式
