This file details the results (message traces) the GUI behaviour
tester app gave under real Windows for various events. It was useful for some of my debugging at least, perhaps it could be of some use to other Wine GUI debuggers as well.

My tests show that Windows window management events behave like described
|
||||
in this file, at least under Win98.
|
||||
The (16/32) or (16) or (32) at the end shows whether the sequence has been
|
||||
confirmed for win16, win32, or both.
|
||||
|
||||
Window Edge Styles (Win95/98 look):
|
||||
WS_EX_DLGMODALFRAME: double border, WS_CAPTION allowed
|
||||
WS_DLGFRAME: double border, WS_CAPTION not allowed (but possibly shown anyway)
|
||||
WS_THICKFRAME: thick border
|
||||
WS_BORDER (default for top-level windows): single black border
|
||||
none (default for child windows): no border
|
||||
|
||||
CreateWindow (for overlapped window, not initially visible) (16/32)
