How to Implement a Drag and Drop Control in Win32

LoveC 61

In Win32, I want to achieve the same effect as those controls in Visual Studio software. For example, some controls can be separated from the main window and turned into a window, which will be absorbed when the control is moved into the window with the mouse. Can a friend tell me what to do...Thanks,Very much!!!!!!!Everyone!!!!

Whether you want to create DockablePane in win32？Do you mind using MFC？ If you prefer to use MFC，you could try to use CDockablePane Class. The CDockablePane class can be used to create docks. Other controls can be integrated into the derived classes of CDockablePane.

As far as I'm concerned, there is nothing directly available API in Win32 to implement this, it is usually made up of framework wrappers (such as MFC... ) implementation.

If you want to try to achieve this effect without MFC. I suggest you could try to use UI Automation to implement control patterns.

I suggest you could follow the following Docs:
Implementing UI Automation Control Patterns
Dock Control Pattern
Drag Control Pattern
DropTarget Control Pattern
