代码如下（示例）：

cpp 复制代码

#include "parametersetting.h"
#include "ui_parametersetting.h"

ParameterSetting::ParameterSetting(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::ParameterSetting)
{
    ui->setupUi(this);

    //QObject::connect(ui->pushButtonSetting, SIGNAL(clicked()), this, SLOT(on_settingConfirm_clicked()));
    QObject::connect(ui->pushButtonSetting, SIGNAL(clicked()), this, SLOT(settingConfirm_clicked()));


    QObject::connect(ui->pushButton, SIGNAL(clicked()), this, SLOT(subwin1Click()));
    QObject::connect(ui->pushButton_2, SIGNAL(clicked()), this, SLOT(subwin2Click()));
    QObject::connect(ui->pushButton_3, SIGNAL(clicked()), this, SLOT(subwin3Click()));
    QObject::connect(ui->pushButton_4, SIGNAL(clicked()), this, SLOT(subwin4Click()));
    QObject::connect(ui->pushButton_5, SIGNAL(clicked()), this, SLOT(subwin5Click()));
    QObject::connect(ui->pushButton_7, SIGNAL(clicked()), this, SLOT(subwin6Click()));
    QObject::connect(ui->pushButton_8, SIGNAL(clicked()), this, SLOT(subwin7Click()));
    QObject::connect(ui->pushButton_9, SIGNAL(clicked()), this, SLOT(subwin8Click()));
    QObject::connect(ui->pushButton_6, SIGNAL(clicked()), this, SLOT(subwin9Click()));
    QObject::connect(ui->pushButton_10, SIGNAL(clicked()), this, SLOT(subwin10Click()));
    QObject::connect(ui->pushButton_12, SIGNAL(clicked()), this, SLOT(subwin11Click()));
    QObject::connect(ui->pushButton_11, SIGNAL(clicked()), this, SLOT(subwin12Click()));
