C ++ - Qt - Visual Studio 2010 - 应用程序与gui和控制台 [英] C++ - Qt - Visual Studio 2010 - application with both gui and console

问题描述

如果没有为程序提供参数，它将作为GUI应用程序启动，如果给定args，则通过命令行运行。我能够得到visual studio来显示和打印到控制台与属性>链接器>子系统（控制台/ SUBSYSTEM：CONSOLE），但这使得控制台总是显示，当应用程序启动时，我如何选择性地显示控制台，以便当应用程序运行与GUI它不会出现。我已经浏览了网站，但我所找到的是如何设置它只是一个Windows应用程序，我需要它作为

If no arguments are given to the program it launches as a GUI application, if it is given args it is run through the command line. I was able to get visual studio to display and print to the console with Properties>Linker>SubSystem (Console/SUBSYSTEM:CONSOLE), but this makes it so that the console always displays when the application is launched, how can I selectively display the console so that when the app is run with the GUI it does not appear. I have looked through the site, but all I have found is how to set it to only be a windows application, and I need it to function as both

。

推荐答案

这个作品我想：

#include <QtGui/QApplication>
#include <QtGui/QMainWindow>


int
main(int n_app_args, char **app_arg)
{
    QCoreApplication * application = 0;

    if ( n_app_args == 1 )
    {
        application = new QCoreApplication(n_app_args, app_arg);
    }
    else
    {
        application = new QApplication(n_app_args, app_arg);
        QMainWindow * mainWindow = new QMainWindow();
        mainWindow->show();
    }


    return application->exec();
}

使用参数调用它，你会得到一个（空）窗口。调用它没有参数，没有窗口。

Call it with an argument and you get a little (empty) window. Call it with no argument and no window.
