Windows SDK: What is an owned window?

[ovidiucucu]

Q: What is an owned window?

A: An owned window is a top-level window that has an owner.
It has the following properties:

• being a top-level window, it can be displayed anywhere in the screen;
• it stays always in the front of its owner window;
• it is hidded when its owner is hidden or minimized;
• it is destroyed when its owner is being destroyed;

Notes

• An owned window is created by passing the owner window handle as hWndParent parameter in CreateWindow(Ex) function call.
• WS_CHILD style must not be set, otherwise results a child and not an owned top-level window.

Example

// create an owned top-level window
HWND hWnd = CreateWindow(szWindowClass, szTitle, 
              WS_OVERLAPPED, // WS_CHILD style is not set
              CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, 
              hWndParent,    // handle to the OWNER window
              NULL, hInstance, NULL);
