1. SS_NOTIFY and mouse clicks
This is a multi-part message in MIME format.

I am using static controls with the SS_NOTIFY style to draw myself some fancy
special controls.
It works fine but I get a w2HClick handler call for both the "click" and
"unclick" events, and I can't find any way to differentiate one from the other. I
am using a simple toggle which is not far off what I want but it is pretty easy
to fool it.
Can anyone tell me either how to respond only to "click" events or to tell if
the mouse button is down or up? I have looked in the Win32Lib docs but can't find
either ....

What's an "unclick" event? A click event is a combination of Mousedown
followed by MouseUp, within the double-click period, and within a few
pixels of each other.
By "click" are you meaning the MouseDown event and "unclick" the mouse UP
event? If so, set you hander for w32HMouse events and watch for Down/Up
events for the left and/or right button.

Why does it have to be within the double-click period? If I press down
the mouse button, I wait a second, and release the button without moving
the mouse, shouldn't that count as a click?
Certain people have heavy fingers, and when they press down a mouse button,
it's physically tough to lift their heavy finger to release the button.
I think it is important to make your applications accessible, also for
people with heavy fingers.

Maybe. On things like buttons and menus, things that have a specific
Microsoft generated click event, the time delay is not significant. But on
things like bitmaps, windows, labels etc... it might be.
To me the 'concept' of a click is a short-sharp action (relatively speaking)
which is different from a mouse up/down event. THat's why I choose to
implement it this way.

Such people already tend to have set their double-click period to a
reasonable length for themselves.
However, I can easily set up Win32lib so that the coder has a choice over
this aspect of a click event. It'll be in the next version for you.

'coder' ?
Ok, this'll be great for us folks who fall asleep at the mouse,
... or still use a 386SX16 at 8 mhz.
Seriously though, a more useful win32lib function might be one that prints
out cheques to the user as recipient, with ...you know, ...Derek Parnell's
signature !
Please!

Well, I don't need the feature, so you don't have to do it for me.
The reason I'm asking, is because I'm working on Win4Eu, and I've just
implemented the Click-event myself. I've looked at your implementation
in Win32Lib, and I've looked at Microsoft's implementation for the
.NET framework (which is a lot more complicated).
Their implementation doesn't even check the mouse movement. They just
check if the mouse cursor is still on the control. So if you press the
mouse button on a control, you move the cursor around (over other controls),
you move the cursor back over the original control and release the button,
a click-event is generated.
My current implementation is a bit of both worlds: it does check if the
mouse has moved a lot, but it doesn't check the time between pressing
and releasing the button.
