qt自定义控件-多类别提示框

2023-10-30

一、前言

用惯了自带的messagebox，或者感觉效果不是很好看，或者有界面的特殊美观需求等等，那么就定制吧。

1.单选项提示框

2.双选项提示框

3.滚动选项提示框

4.密码提示框

5.多组合选项提示框1

6.多组合选项提示框2

7.多组合选项提示框3

二、环境

qt57

window10

三、正文

画布多少，直接说核心部分

1.单选项提示框

背景是哥图片，可以自定义为任何不规则图片，然后传输想要显示的文本通过槽函数发送信号，新建一个widget用于显示，打开之后再初始化中加入定时器自动关闭界面，避免长时间没操作。

messagebox1.h

protected:
    void paintEvent(QPaintEvent *paintevent);
private slots:
    void on_pushButton_clicked();
    void receivetext(QString res);
private:
    Ui::MessageBox1 *ui;
    QPixmap pic;

messagebox1.cpp

#include "messagebox1.h"
#include "ui_messagebox1.h"

MessageBox1::MessageBox1(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::MessageBox1)
{
    ui->setupUi(this);
    this->setWindowModality(Qt::ApplicationModal);//设置一直保持在顶端，不可切换其他界面，除非被新界面带此属性覆盖
    this->setWindowFlags(Qt::FramelessWindowHint);//设置窗体无边框
    this->setAttribute(Qt::WA_TranslucentBackground);//设置背景透明
    pic.load(tr(":/PIC/background/message1.png"));//设置背景
    //倒计时关闭界面
    for(int i=0;i<10;i++)
        QTimer::singleShot(i*1000,this,[=](){ui->pushButton->setText(QString("确认(%1)").arg(9-i));});
    QTimer::singleShot(10*1000,this,[=](){this->close();});
    ui->pushButton->setFocus();//设置聚焦，作用你懂的
}
MessageBox1::~MessageBox1()
{
    delete ui;
}
void MessageBox1::paintEvent(QPaintEvent *paintevent)
{
    paintevent->ignore();
    QPainter painter(this);
    painter.drawPixmap(0, 0, pic);//绘制图像
}
void MessageBox1::on_pushButton_clicked()
{
    this->close();
}
void MessageBox1::receivetext(QString res)
{
    ui->label->setText(res);
}

ui中加入button和label即可

主函数调用

    MessageBox1 * box = new MessageBox1();
    box->show();
    box->setAttribute(Qt::WA_DeleteOnClose);//若是关闭界面，则彻底释放资源
    connect(this,SIGNAL(sendtext(QString)),box,SLOT(receivetext(QString)));
    emit sendtext("提示!\r\n这是一个测试消息！");

2.双选项提示框

参考上面的，核心部分就是观测exec返回值0或1，代表是否点击确认，还是点击取消，还是强制或者自动关闭的提示框界面，默认确认为1，其余为0

在初始化里加入this->reject();//exec返回值为0

在确认按键点击之后加入this->accept();//exec返回值为1

主函数调用

    MessageBox2 * box = new MessageBox2();
    box->show();
    box->setAttribute(Qt::WA_DeleteOnClose);//若是关闭界面，则彻底释放资源
    connect(this,SIGNAL(sendtext(QString)),box,SLOT(receivetext(QString)));
    emit sendtext("提示!\r\n这是一个测试消息！");
    qDebug()<<box->exec();

这里的判断box->exec()返回值就和正常的messagebox使用判断一样了

3.滚动选项提示框

主要就是把第2个的label换成了一个自定义控件，自定义控件的功能是滚动选择，然后绑定一些槽配套使用再传递给主函数即可

messagebox3.h

#define MESSAGEBOX3_H

    QString choose;

#endif // MESSAGEBOX1_H

    painter.drawPixmap(0, 0, pic);//绘制图像
}
void MessageBox3::on_btn_sure_clicked()
{
    emit sendchoose(choose);
    this->close();
}
void MessageBox3::on_btn_false_clicked()
{ 
    this->close();
}
void MessageBox3::receivetext(QStringList res,int num)
{
    m_strlist=res;//m_strlist备用
    roll->setRange(res);
    choose=res.at(num);//设置当前值，避免直接不改变直接确认返回值无效
    roll->setCurrentStr(choose);
    //qDebug()<<res;
}

slidingselector自定义控件下载

ui中将label改为horizontalLayout即可

主函数调用

    MessageBox3 * box = new MessageBox3();
    box->show();
    box->setAttribute(Qt::WA_DeleteOnClose);//若是关闭界面，则彻底释放资源
    connect(this,SIGNAL(sendtext(QStringList,int)),box,SLOT(receivetext(QStringList,int)));
    QStringList list;
    list<<"str撒撒发生111"<<"str撒撒发生22"<<"str撒撒发生33"<<"str撒撒发生44"<<"str撒撒发生55"<<"str撒撒发生66";
    emit sendtext(list,2);
    connect(box,&MessageBox3::sendchoose,[=](QString res){
        qDebug()<<res;
    });

滚动自定义控件简介，可设置为横向或者竖着刷新模式，可设置为数字或者字符串刷新模式，数字模式传入范围值即可，字符串模式传入参数QSteingList即可，可以把目前列表中的值传入让其显示。所有部分颜色均可更改

4.密码提示框

入口函数：

        MessageBox4 * box = new MessageBox4();
        box->show();
        box->setAttribute(Qt::WA_DeleteOnClose);//若是关闭界面，则彻底释放资源
        connect(this,SIGNAL(sendtext(QString)),box,SLOT(receivetext(QString)));
        emit sendtext("sy1234");
        qDebug()<<box->exec();

核心代码

//振动效果
void MessageBox4::widgetShake(QWidget *pWidget, int nRange)
{
    int nX = pWidget->x();
    int nY = pWidget->y();
    QPropertyAnimation *pAnimation = new QPropertyAnimation(pWidget,"geometry");
    pAnimation->setEasingCurve(QEasingCurve::InOutSine);
    pAnimation->setDuration(300);
    pAnimation->setStartValue(QRect(QPoint(nX,nY),pWidget->size()));

    int nShakeCount = 20; //抖动次数
    double nStep = 1.0/nShakeCount;
    for(int i = 1; i < nShakeCount; i++){
        nRange = i&1 ? -nRange : nRange;
        pAnimation->setKeyValueAt(nStep*i,QRect(QPoint(nX + nRange,nY),pWidget->size()));
    }

    pAnimation->setEndValue(QRect(QPoint(nX,nY),pWidget->size()));
    pAnimation->start(QAbstractAnimation::DeleteWhenStopped);
}
//打开屏幕键盘
void MessageBox4::on_pushButton_keyboard_clicked()
{
    //The code from david!!!
    PVOID OldValue;
    BOOL bRet = Wow64DisableWow64FsRedirection (&OldValue);
    QString csProcess="C:\\Windows\\System32\\osk.exe";
    QString params="";
    ShellExecute(NULL, L"open", (LPCWSTR)csProcess.utf16(), (LPCWSTR)params.utf16(), NULL, SW_SHOWNORMAL);
    if ( bRet )
    {
        Wow64RevertWow64FsRedirection(OldValue);
    }
    ui->lineEdit->setFocus();
}
void MessageBox4::closeEvent(QCloseEvent *event)
{
    HWND appWnd;
    appWnd = ::FindWindow(L"OSKMainClass", NULL);
    if (appWnd){
       SendMessage(appWnd, WM_SYSCOMMAND, SC_CLOSE, 0);
       //qDebug() << "closeKeyboard succeed";
    }
    else{
       //qDebug() << "closeKeyboard failed";
     }
}

使用原理。传出进入密码，点击确定之后会判断面膜是否正确，若密码正确，则返回exec值为1，若不正确，会提示密码错误

5.多组合选项提示框1

入口函数：

        MessageBox5 * box = new MessageBox5();
        box->show();
        box->setAttribute(Qt::WA_DeleteOnClose);//若是关闭界面，则彻底释放资源
        connect(this,SIGNAL(sendtext(QStringList,QStringList)),box,SLOT(receivetext(QStringList,QStringList)));
        QStringList list1,list2;
        list1<<"str撒撒发生111"<<"str撒撒发生22"<<"str撒撒发生33"<<"str撒撒发生44"<<"str撒撒发生55"<<"str撒撒发生66";
        list2<<"aa"<<"bb";
        emit sendtext(list2,list1);
        connect(box,&MessageBox5::sendchoose,[=](QString res1,QString res2,QDate t1,QDate t2){
            qDebug()<<res1<<res2<<t1<<t2;

            ui->stackedWidget->setCurrentIndex(i);
            groupbtn[i]->setChecked(true);
        });

原理：就是采用多个滑动选择器组合，配合一些逻辑，时间的改变逻辑占用一些代码行，在年份和月份改变时，日期对应的上限要跟着改变

6.多组合选项提示框2

入口函数

        MessageBox6 * box = new MessageBox6();
        box->show();
        box->setAttribute(Qt::WA_DeleteOnClose);//若是关闭界面，则彻底释放资源
        connect(this,SIGNAL(sendtext(QStringList)),box,SLOT(receivetext(QStringList)));

            qDebug()<<res1<<res2<<res3<<res4;
        });

原理：就是普通的lineedot输入，传入参数中有当前多有的账号信息判断，进入后删除本身的信息，确定判断是否存在当前存在的账号信息，进行振动提示，输入内容为空也振动提示，注意函数判断空时用isempty，isnull是无效i的
