1、堆栈窗体的使用

stack.h

#ifndef STACK_H
#define STACK_H
#include
class StackDlg:public QDialog
{
    Q_OBJECT
public:
    StackDlg(QWidget *parent=0,Qt::WindowFlags f1=0);
    QLabel *label1;
    QLabel *label2;
    QLabel *label3;
    QListWidget *list;
    QStackedWidget *stack;
};
#endif

 

stack.cpp

#include "stack.h"
StackDlg::StackDlg(QWidget *parent,Qt::WindowFlags f1)
    :QDialog(parent,f1)
{
    setWindowTitle(tr("stack widigets"));
    list=new QListWidget(this);
    list->insertItem(0,tr("Window1"));
    list->insertItem(1,tr("Window2"));
    list->insertItem(2,tr("Window3"));

    label1=new QLabel(tr("This is Window1!"));
    label2=new QLabel(tr("This is Window2!"));
    label3=new QLabel(tr("This is Window3!"));

    stack=new QStackedWidget(this);
    stack->addWidget(label1);
    stack->addWidget(label2);
    stack->addWidget(label3);

    QHBoxLayout *mainLayout=new QHBoxLayout(this);
    mainLayout->setMargin(4);
    mainLayout->setSpacing(4);
    mainLayout->addWidget(list);
    mainLayout->addWidget(stack,0,Qt::AlignHCenter);
    mainLayout->setStretchFactor(list,1);
    mainLayout->setStretchFactor(stack,3);

    connect(list,SIGNAL(currentRowChanged(int)),stack,SLOT(setCurrentIndex(int)));

}

main.cpp

#include
#include
int main(int argc,char *argv[])
{
    //QFont font("ZYSong18030",8);
   // QApplication::setFont(font);

    QApplication a(argc,argv);
    QTranslator translator(0);
    translator.load("stack_zh",".");
    a.installTranslator(&translator);

    StackDlg stack;
    stack.show();
    return a.exec();
}
