QT5 QStackedWidget使用的问题

刹那X逍遥 2016-05-29 04:21:23

addWidget()与setCurrentIndex()配套使用，有顺序要求吗？
第一个addWidget引索为0？以后依次增加？
调用setCurrentIndex()就会切换到引索对应的页面？



#include "ManagerManage.h"

#include "ui_ManagerManage.h"



ManagerManage::ManagerManage(QWidget *parent) :

    QDialog(parent),

    ui(new Ui::ManagerManage)

{

    ui->setupUi(this);

    this->setWindowTitle("管理员界面");



    //连接退出系统按钮信号和槽

    connect(ui->ButtonExit, SIGNAL(clicked()), this, SLOT(ButtonExitSlot()));

    //连接返回按钮信号和槽

    connect(ui->ButtonReturn, SIGNAL(clicked()), this, SLOT(ButtonReturnSlot()));



    //创建管理学生窗口

    managerstudent = new ManagerStudent;

    ui->StackedManager->addWidget(managerstudent);

    connect(ui->ButtonStudent, SIGNAL(clicked()), this, SLOT(ButtonStudentSlot()));

    //创建管理教师窗口

    managerteacher = new ManagerTeacher;

    ui->StackedManager->addWidget(managerteacher);

    connect(ui->ButtonTeacher, SIGNAL(clicked()), this, SLOT(ButtonTeacherSlot()));

    //创建修改密码窗口

    managerchange = new ManagerChange;

    ui->StackedManager->addWidget(managerchange);

    connect(ui->ButtonChange, SIGNAL(clicked()), this, SLOT(ButtonChangeSlot()));

    connect(managerchange, SIGNAL(returnBlank()), this, SLOT(setbtnEnableSlot()));



    //实现个功能窗口与管理窗口信号槽连接，用于设置button的属性

    //connect(ManagerStudent, SIGNAL(EmitToManagerManage()), this, SLOT(setbtnEnableSlot()));

    //connect(ManagerTeacher, SIGNAL(EmitToManagerManage()), this, SLOT(setbtnEnableSlot()));

    //connect(managerchange, SIGNAL(EmitToManagerManage()), this, SLOT(setbtnEnableSlot()));

    connect(managerchange,SIGNAL(newPassword()),this,SLOT(on_returnButton_clicked()));



}

ManagerManage::~ManagerManage()

{

    delete ui;

}



void ManagerManage::ButtonExitSlot()

{

    if(QMessageBox::question(this,"提示","是否退出系统?",QMessageBox::Yes|QMessageBox::No)==QMessageBox::Yes)

    {

    this->close();

    delete this;

    }

}

void ManagerManage::ButtonReturnSlot()

{

    if(QMessageBox::question(this,"提示","是否退出登录?",QMessageBox::Yes|QMessageBox::No)==QMessageBox::Yes)

    {

    emit toLoginDialog();

    delete this;

    }

}



void ManagerManage::on_returnButton_clicked()

{

    emit toLoginDialog();

    delete this;

}

void ManagerManage::ButtonStudentSlot()

{

    this->setbtnfalse();

    managerstudent->show();

    ui->StackedManager->setCurrentIndex(0);

}

void ManagerManage::ButtonTeacherSlot()

{

    this->setbtnfalse();

    managerteacher->show();

    ui->StackedManager->setCurrentIndex(1);

}

void ManagerManage::ButtonChangeSlot()

{

    this->setbtnfalse();

    //this->hide();

    managerchange->show();

    ui->StackedManager->setCurrentIndex(2);

}

我点修改密码，结果弹出两个，怎么回事啊

你直接调用setCurrentIndex应该就可以了为，不需要再去操作页面本身的显示的

(⊙v⊙)嗯，我解决了。


void ManagerManage::ButtonStudentSlot()
{
    this->setbtnfalse();
    //managerstudent->show();
    ui->StackedManager->setCurrentIndex(2);
}
void ManagerManage::ButtonTeacherSlot()
{
    this->setbtnfalse();
    //managerteacher->show();
    ui->StackedManager->setCurrentIndex(3);
}
void ManagerManage::ButtonChangeSlot()
{
    this->setbtnfalse();
    //managerchange->show();
    ui->StackedManager->setCurrentIndex(4);
}

void ManagerManage::setBlank()
{
    ui->StackedManager->setCurrentIndex(1);
    this->setbtntrue();
}
