There is no cross-platform way to do this in C++

Now that we have that out of the way, Felice Pollano's answer provides the Windows API so you can manipulate the clipboard in Windows.

Apple provides an example application named ClipboardViewer and an entire reference to the NSPasteBoard and the functionality it provides.

As for Linux, it depends on what windowing manager you are running.

Answer 2

You can use ClipboardXX.

Just download ClipboardXX.hpp from github and copy it to your project path. Then you can do something like:

#include "../ClipboardXX.hpp"
#include <string>

int main(){
    CClipboardXX clipboard;

    // copy
    clipboard‌ << "text you wanna copy";

    // paste
    std::string paste_text;
    clipboard >> paste_text;
}

This is cross platform too.

Answer 3

There is a cross platform way to do this in C++, provided you are willing to use the Qt Library.

Answer 4

In windows look at the following API:

• OpenClipBoard
• EmptyClipboard
• SetClipboardData
• CloseClipboard
• GetClipboardData

An extensive discussion can be found here. Obviously this topic is strongly operating system related. And if you are using some framework (ie MFC/ATL) you generally find some helper infrastructure. This reply refer to the lowest API level in WIndows. If you are planning to use MFC have a look here, if you prefer ATL look here.

Answer 5

If you are looking for a simle way to do this : simulate the keyboard combination ctrl + v and you are done with it. On all platforms.
