【Qt】修改用戶資料

這是一個簡單的修改用戶資料的例子，在這個例子裏可以看到如何實現一個相對較爲複雜的窗口布局，如何使用分割窗口，如何使用堆棧窗口等，效果圖如下：

代碼的實現有點多，但是我已經盡力備註，方便大家的理解，建議看着效果圖和註釋一起理解這些佈局，要堅持看下去，希望能對你有所幫助，具體代碼如下：

//main.cpp

<span style="font-family:Microsoft YaHei;font-size:18px;">#include "content.h"
#include <QApplication>
#include <QTextCodec>
#include <QSplitter>
#include <QListWidget>


int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QFont font("AR PL KaitiM GB",12);//設置字體
    a.setFont(font);

    QSplitter *splitterMain =new QSplitter(Qt::Horizontal,0);//水平分割窗口，作爲主佈局
    splitterMain->setOpaqueResize(true);//可調整大小

    QListWidget *list=new QListWidget(splitterMain);//在新建的主窗口的左側插入一個QlistWidget作爲條目選擇框

    list->insertItem(0,QObject::tr("基本信息"));
    list->insertItem(1,QObject::tr("聯繫方式"));
    list->insertItem(1,QObject::tr("詳細資料"));

    Content *content=new Content(splitterMain);//在水平分割窗的右側窗口中插入content類對象

    QObject::connect(list,SIGNAL(currentRowChanged(int)),content->stack,SLOT(setCurrentIndex(int)));//連接列表框中的currentRowChanged()信號與堆棧窗的setCurrentIndex()槽函數

    splitterMain->setWindowTitle(QObject::tr("修改用戶資料"));//主佈局的標題
    splitterMain->setMinimumSize(splitterMain->minimumSize());//設置主佈局框即水平分割窗的最小尺寸
    splitterMain->setMaximumSize(splitterMain->maximumSize());//設置主佈局框的最大尺寸
    splitterMain->show();

    //Content w;
    //w.show();

    return a.exec();
}
</span>

    baseInfo =new BaseInfo;//在堆棧窗口中插入“基本信息”，"聯繫方式“，”詳細資料“
    contact =new Contact();
    detail =new Detail();
    stack->addWidget(baseInfo);//往stack裏添加控件
    stack->addWidget(contact);
    stack->addWidget(detail);
    AmendBtn =new QPushButton(tr("修改"));
    CloseBtn =new QPushButton(tr("關閉"));
    QHBoxLayout *BtnLayout =new QHBoxLayout;//水平佈局
    BtnLayout->addStretch(1);//增加伸縮量，按比例分配空間
    BtnLayout->addWidget(AmendBtn);
    BtnLayout->addWidget(CloseBtn);//這段代碼用於創建兩個按鈕，並且利用QHBoxLayout對其進行佈局

    QVBoxLayout *RightLayout =new QVBoxLayout(this);//對整體進行佈局
    RightLayout->setMargin(10);//設置邊緣，佈局與四周的距離
    RightLayout->setSpacing(6);//設置間隔，佈局與下邊框的距離
