C++ - How to hide other application's window

I am trying to create a software(Qt/C++). In which I need a functionality that hiding other application windows based on their window titles. Hiding means invisible not minimize. Can any body say how to achieve this?. I am currently working on Windows platf开发者_运维技巧orm.

Note: If you provide a solution via Qt, it will give more comfort. Because it provides the platform independency.

For Windows, if you have an HWND to another application's window, you can call the ShowWindow function, like this:

ShowWindow(hWnd, SW_HIDE);

You can get an HWND to another application's window using the FindWindow API function.

Interacting with other applications like this is necessarily platform-specific. There is no generic way to do this using Qt, because Qt is a framework for your application, not anybody else's.

Here you can find a tutorial on how to make a window transparent on windows.

As mentionied before, you must find the window's handle by it's title using the API.
