Qt has never provided good support for the underlying system, such as serial port communication and global hotkeys that we often use. Since Qt may not be supported for some reason, we can only write code and call system-related APIs.
Note: This is Windows.These codes only support windows. At the same time, it also indicates that there must be other platforms to write.
To call the Windows API in Qt, you only need to add # include

Generally, a hook is used to obtain the system's buttons or mouse actions, and then perform custom actions before the system responds, or directly truncate the message, this is the principle of shielding system hotkeys. First, call the DLL file of the operating system and introduce the namespace using system. runtime. interopservices; call the dynamic link library of the operating system [dllimport ("user32.dll", charset = charset. auto, setlasterror

HWnd: The Window handle for receiving the WM_HOTKEY message generated by the hotkey. If this parameter is NULL, The WM_HOTKEY message passed to the calling thread must be processed in the message loop.
Id: The identifier that defines the hotkey. Other hotkeys in the call thr
I first came into contact with the C # language and then learned Win32 and MFC.
Some puzzling problems have been encountered during the learning process of transformation. For example, it takes a long time for system-level functions to be implemented in Win32 and MFC after being implemented in C. The following describes how to implement common functions in these three environments.
This article describes how to set system-level hotkeys:

A friend asked me how to press the F1 key to implement the paste (Ctrl + V) function a few days ago. Baidu sent a method to him, he can't understand it (he is a former codenon of Boss), so I made a Demo for his reference. Today is empty. I will sort out the Demo for your reference.

corresponding code in the WM_HOTKEY message response function to activate the background of the service program.
Registration of system hotkeys
According to the previous introduction, it is not difficult to write the code that adds the system hotkey response to the background service program. First, use the globalfindatom () function to check whether the global atom corresponding to the service program already exists in the global atomic table. If it
Add the control hotkeys we want to the controls in MFC, before you start, it must be clear that the hotkey is divided into local and global, where local functions are active when the current program has focus (activated), and global, whenever it is active, Test local to take precedence over global, that is, if the shortcut key of the active window overlaps with the shortcut key of the inactive window, the current activation window will first respond.

How to use:
Copy Code code as follows:
$.hotkeys.add (' Key Name ', function () {The purpose to be implemented});
The key name can be either a single key or a combination key, for example: Ctrl + C means to press CTRL and C. simultaneously.
To cancel an event for a key:
Copy Code code as follows:
$.hotkeys.remove (' key Name ');
