Deconstraining Cursor While Moving Window

Hello,

When you move a child window (if you have it set up so that part of the child window pretends its the caption area), the cursor is confined to the parent window's client area. I imagine this due to either calling ClipCursor at the start of movement or SetCursorPos in a conditional manner every time the window is moved.

Is there a way that I can free the cursor from those bounds?

So you want a child window to be able to be moved outside the parent?

Well, no. The thing is I'm trying to get a dockable window system going. I want the child window to be stuck to the parent unless the cursor (left button down) moves a sufficient distance away, then the window will be promoted to a top-level window.

The cursor currently can't leave the parent while it is moving the child.

EDIT: Ah, think I figured it out:-

Code:

---

// In dockable window's standard WindowProc uMsg switch
case WM_ENTERSIZEMOVE:
{
    ClipCursor(NULL);
    break;
}
