blocks|key|1010720|text|该功能并未内置到Qt应用程序(或任何窗口或其他框架AFAIK)中，但如果您同时创建了这两个程序，则可以在自己的程序中构建它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1010721|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

That functionality is not built-in to Qt applications (or any window other fraemwork AFAIK), but you can build it in yourself if you are creating both programs.

blocks|key|830203|text|开始这样做的最好方法是使用QSharedMemory在两个进程中访问相同的内存，然后您所描述的应该是完全可能的。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|830204|entityMap|0|LINK|mutability|MUTABLE|url|http://doc.trolltech.com/4.5/qsharedmemory.html^0|D|D|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

The best way to start doing this would using <a href="http://doc.trolltech.com/4.5/qsharedmemory.html" rel="nofollow noreferrer">QSharedMemory</a> to access the same memory in both processes and then what you describe should be perfectly possible.

blocks|key|830244|text|如果您可以使其他应用程序成为由主应用程序加载的dll/共享库。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|830245|然后只需在dll中创建一个绘制菜单或绘制框架的方法。主应用程序检查dll是否存在并加载它，然后它可以检查gui方法是否存在-这是实现gui插件的常用方法。|830246|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

If you can make the other app a dll/shared library that is loaded by the main app. 
Then simply have a method draw menu or draw frame in the dll. The main app checks if the dll is present and loads it, it can then check if the gui method exists - this is the common way to implement gui plugins.

blocks|key|3146437|text|最简单的方法是从主程序(绘制程序)公开一组函数，并从“客户端”加载它们，然后在需要时简单地调用它们。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3146438|另一种需要更多工作的方法是使用某种类型的进程间通信(例如共享内存、套接字、d-bus等)。对于实现，您可以使用Qt提供的那些或boost)：|offset|length|3146439|使用套接字的一个简化示例是让主程序监听套接字，等待命令，并为每个命令调用正确的函数。而另一程序在接收到来自提示符的命令时与其通信。|3146440|entityMap|0|LINK|mutability|MUTABLE|url|http://www.boost.org/doc/libs/1_39_0/doc/html/interprocess.html^0|0|1R|5|0|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@$D|R|E|S|1|T]]|A|$]]|$1|F|3|G|5|6|7|U|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|O]]]]

The easiest way would be to expose a set of functions from the main program (the one that draws) and load them from the "client" and simply call them when you need to.

Another approach that requires more work would be to use some sort of inter-process communication (such as shared memory, sockets, d-bus etc. for implementations you can either use the ones that Qt offers or <a href="http://www.boost.org/doc/libs/1_39_0/doc/html/interprocess.html" rel="nofollow noreferrer">boost</a>): 

A simplified example using sockets would be to have the main program listen on a socket waiting for commands and invoking the right function for each command. While the other program communicating with it upon receiving commands from the prompt.

blocks|key|3146480|text|如前所述，这是可能的。如果您需要特定于域的脚本语言，我建议您使用QtScript+module。它基于ECMAScript+262，允许访问信号、插槽和其他内容。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|3146481|尽管您可以使用IPC或TCP来控制应用程序，但Qxt提供的QxtRPCPeer可用于在通过QIODevice连接的应用程序之间连接信号和插槽。|style|CODE|3146482|entityMap|0|LINK|mutability|MUTABLE|url|http://doc.qtsoftware.com/4.5/qtscript.html|1|http://doc.libqxt.org/0.5.0/classQxtRPCPeer.html^0|W|F|0|0|T|A|T|A|1|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@$A|S|B|T|1|U]]|C|$]]|$1|D|3|E|5|6|7|V|8|@$A|W|B|X|F|G]]|9|@$A|Y|B|Z|1|10]]|C|$]]|$1|H|3|-4|5|6|7|11|8|@]|9|@]|C|$]]]|I|$J|$5|K|L|M|C|$N|O]]|P|$5|K|L|M|C|$N|Q]]]]

As already stated, it is possible. If you need a domain specific scripting language, I'd recommend using the <a href="http://doc.qtsoftware.com/4.5/qtscript.html" rel="nofollow noreferrer">QtScript module</a>. It's based on ECMAScript 262 and allows access to signals, slots, and other things.

Although you could use IPC or TCP for controlling the application, Qxt provides <a href="http://doc.libqxt.org/0.5.0/classQxtRPCPeer.html" rel="nofollow noreferrer"><code>QxtRPCPeer</code></a> that can be used to connect signals and slots between applications connected via a QIODevice, such as a TCP or local connection.

Is there any way to open a Qt process and then programatically add widgets? For example, start a process that opens a frame and then, with another call from, say, another program (that is mine; actually another scripting language), add a button to that frame?

So, in another program, I say "open frame" at the prompt and the frame opens. And then I say "add button" and the frame just opened is populated with a button.

有没有办法打开Qt进程，然后以编程方式添加小部件？例如，启动一个打开框架的进程，然后从另一个程序(这是我的程序；实际上是另一种脚本语言)调用另一个程序，向该框架添加一个按钮？因此，在另一个程序中，我在提示符处输入"open frame“，然后框架就会打开。然后我说“添加按钮”，刚打开的框架中就有一个按钮。更新为地址注释...
