Qt控制台和带窗口的区别

#include <QtCore/QCoreApplication>

int main(int argc, char *argv[])

{

    QCoreApplication a(argc, argv);

    return a.exec();

}

.pro文件如下

#-------------------------------------------------
 
#

#
 
#-------------------------------------------------
  
QT       += core
 
QT       -= gui
 
TARGET = test1
CONFIG   += console
CONFIG   -= app_bundle
TEMPLATE = app
SOURCES += main.cpp

如果要想变成带窗口的程序需要做如下改变
QCoreApplication a(argc, argv);
变成
QApplication a(argc, argv);

QCoreApplication 
是控制台的Application
QApplication 
  
是带窗口的Application




最后变化如下

#include <QtGui/QApplication>
 
#include <QtCore>
 
#include <QWebView>
 
#include <QWebFrame>
 
#include <QThread>
 
#include <QUrl>
  
int main(int argc, char *argv[])
 
{
 
    QApplication a(argc, argv);
 
    QTextStream out(stdout);
 
    out << "start";
   
    QWebView * pWebView = new QWebView();
  
    pWebView->load(QUrl("http://bj.58.com"));
 
    pWebView->show();
     
    out<<pWebView->page()->mainFrame()->toHtml();
  
    //SleeperThread::sleep(-1);
   
    printf("aaa");
 
    return a.exec();
 
}
