The following styles can be specified wherever a window style is required.
After the control has been created, these styles cannot be modified, except
as noted.
Constants

parent window. This style is used when creating the parent window.
WS_CLIPSIBLINGS
Clips child windows relative to each other; that is, when a particular child
window receives a WM_PAINT message, the WS_CLIPSIBLINGS style clips all other
overlapping child windows out of the region of the child window to be

possible, when drawing within the client area of a child window, to draw
within the client area of a neighboring child window.
