qt中的TabWidget应用程序框架

#include <QMainWindow>

//-----------------------------------------------------------------------  1

//整体基于

class MainWindow : public QMainWindow

{

private slots:

void open();

void close();

void tabCloseRequested(int index); 

}

//-------------------------------------------------------------------------2

void MainWindow::tabCloseRequested(int index)

{

QString tabCaption = ui->tabWidget->tabText(index);

if(QMessageBox::question(this, tr("Message"), tr("是否要关闭窗口：") + tabCaption, QMessageBox::Yes | QMessageBox::No) == QMessageBox::Yes)

delete ui->tabWidget->widget(index);//关闭页签并释放掉对应的widget控件对象

}

//------------------------------------------------------------------------ 3

//构造函数中实现

delete ui->tab;  //删除tabWidget上默认带有的两个页签

delete ui->tab_2;

//新建第一个页面的部件

Dialog222 *label = new Dialog222();

QIcon icon1(":/image/m1.ico");

ui->tabWidget->addTab(label, icon1, "  解 压");

//点击页签上的叉号触发

connect(ui->tabWidget, SIGNAL(tabCloseRequested(int)), this, SLOT(tabCloseRequested(int)));

//----------------------------------------------------------------------  4

void MainWindow::open()

{

ui->tabWidget->removeTab(0);

Dialog222 *label = new Dialog222();

//向QTabWidget中添加第一个页面

QIcon icon1(":/image/m1.ico");

ui->tabWidget->addTab(label, icon1, "  解 压");

}
