[英]How to integrate Qt into an existing C++ project
I am in the process of teaching myself C++. 我正在自学C ++。 I have completed many tutorials, which have all been console projects and I've been using Visual Studio Community 2019 for those.
我已经完成了许多教程,这些教程都是控制台项目,并且我一直在使用Visual Studio Community 2019。 Now I started to work on a project for a colleague that should parse his inbox for specific mails and summarize their contents.
现在,我开始为一个同事开展一个项目,该项目应该解析其收件箱中的特定邮件并总结其内容。
The underlying code for the parsing is already working, now I want to create a simple UI to show the data and most people seem to suggest Qt for that job. 解析的基础代码已经在工作,现在我想创建一个简单的UI来显示数据,大多数人似乎都建议Qt来完成这项工作。 So I also did some tutorials about Qt, which all feature the Qt Creator.
因此,我也做了一些有关Qt的教程,这些教程都具有Qt Creator的功能。
Now I don't mind the Qt creator, I just would like to continue my project on Visual Studio since I'm already quite familiar with it. 现在我不在乎Qt的创建者,我只是想在Visual Studio上继续我的项目,因为我已经很熟悉它了。 I have added the Qt VS Tools to my Visual Studio and I have done the steps described in this thread: add Qt to existing Visual Studio c++ project But now I'm at a complete loss as to how I need to continue and I can't seem to find anything on how to proceed.
我已经将Qt VS工具添加到我的Visual Studio中,并且已经完成了该线程中描述的步骤: 将Qt添加到现有的Visual Studio c ++项目中,但是现在我完全迷失了继续操作的方式,我可以似乎找不到任何进行方法的信息。
Is it possible to convert my project to a Qt application at all or do I have to start from scratch? 是否可以将我的项目完全转换为Qt应用程序,还是必须从头开始? How do I show Qt-generated windows without using the Qt creator?
如何在不使用Qt创建器的情况下显示Qt生成的窗口? I think I need to use the QMake tool to do some of that, but I can't even figure out how I would do that...
我想我需要使用QMake工具来执行其中的一些操作,但是我什至无法弄清楚该怎么做...
Can anyone give me a detailed guide on how I should proceed or link me to one? 谁能给我一份详细的指南,说明如何进行或将我链接到其中?
You need to do the following: 您需要执行以下操作:
#include <QWidget>
and for a button, you would do #include <QPushButton>
. #include <QWidget>
,对于按钮,您将包含#include <QPushButton>
。 You will always need to have do #include <QApplication>
Here is a full list of possible things you can use. #include <QApplication>
这是您可以使用的所有可能事物的完整列表 。 Notice that Qt is much more than just a gui library. QApplication app(argc, argv);
QApplication app(argc, argv);
auto myWindow=new QWidget() ; auto myButton = new QPushButton(myWindow) ;
auto myWindow=new QWidget() ; auto myButton = new QPushButton(myWindow) ;
auto myWindow=new QWidget() ; auto myButton = new QPushButton(myWindow) ;
myWindow->show();
myWindow->show();
return app.exec();
return app.exec();
Like comments say, there are a gazillion ways to get up and running with Qt. 就像评论说的那样,有大量的方法来启动和运行Qt。 Any editor/IDE and any build system will probably get you there, however, I recommend you use QtCreator.
任何编辑器/ IDE和任何构建系统都可能会带您到那里,但是,我建议您使用QtCreator。 Why?
为什么? Because importing existing C++ code into QtCreator project will be simpler than setting up Qt inside existing VS project.
因为将现有C ++代码导入QtCreator项目将比在现有VS项目中设置Qt更为简单。 QtCreator is dead simple plug and play when it comes to Qt stuff, much more so than VS is.
当涉及到Qt时,QtCreator简直就是简单的即插即用,远比VS更是如此。
For one QtCreator comes with a bunch of example project out of the box that you can just click on and press "play" and it will build and run them without any set up. 对于一个QtCreator,它提供了许多示例项目,您可以单击并按“播放”,然后无需任何设置即可构建和运行它们。 Adapting from this is way easier than trying to manually set up a bunch of stuff in VS.
与尝试在VS中手动设置一堆东西相比,适应这一点要容易得多。
Examples in QtCreator: https://youtu.be/R6zWLfHIYJw?t=40 QtCreator中的示例: https ://youtu.be/R6zWLfHIYJw ? t =40
Full example just showing a single button: 完整的示例仅显示一个按钮:
#include <QApplication>
#include <QPushButton>
int main(int argc, char **argv)
{
QApplication app (argc, argv);
QPushButton button ("Hello world !");
button.show();
return app.exec();
}
