Qt实现Element-ui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;

};

namespace Ui {
    class DTPopupWindow: public Ui_DTPopupWindow {};
} // namespace Ui

#endif // UI_DTPOPUPWINDOW_H

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
