1. [Win] ...two rules.
The current definition for WS_OVERLAPPEDWINDOW in win32lib is wrong, and
should actually just be:
or_all({ WS_CAPTION,
WS_SYSMENU,
WS_THICKFRAME,
WS_MINIMIZEBOX,
WS_MAXIMIZEBOX})
So why does it work now....
... simply because it now includes WS_BORDER *and* WS_DLGFRAME,
which... or_all()'s to #C00000, which is,
you guessed it,
actually equivalent to WS_CAPTION.
Here's why it's wrong. ( my *emphasis* )
<from win32.hlp>
WS_DLGFRAME Creates a window with a double border, a style typically used
with dialog boxes. A window with this style *cannot* have a title bar.
WS_SYSMENU Creates a window that has a window-menu in its title bar. The
WS_CAPTION style *must* also be specified.
Which leads to a question someone might be able to answer.
The above style is #CF0000 in any case.
So why does:
printf(1,"style %x\n",
{ w32Func(xGetWindowLong,{getHandle(myMain),GWL_STYLE})})
.. always seem to return #4CF0000 ?
Is WS_CLIPSIBLINGS ( I guess ) always a parent window default ?

Hi Wolf,
> The current definition for WS_OVERLAPPEDWINDOW in win32lib is wrong,
It has the same value as the Microsoft definition in Winuser.h
> Here's why it's wrong. ( my *emphasis* )
This does not mean it is "wrong", just a poor choice of coding style. As
WS_BORDER describes a specific look for window frames and WS_DLGFRAME
describes a different window frame look, one would normally assume that
these two styles are mutually exclusive. However, Microsoft has decided to
"reuse" these values by saying that if you *do* have both then it means
something else entirely different - namely that you want a title bar!
> Is WS_CLIPSIBLINGS ( I guess ) always a parent window default ?
Again, Microsoft in its wisdom has decided that if we create a window that
has child windows, that WS_CLIPSIBLINGS should be used. So therefore if we
don't specify it, Windows will add it in for us. I suspect that if we
actually don't want this style flag, we must explicitly remove the style
after the window has been created.
