1. win32lib question - David Cuny
David, sorry to ask a question that has been answered a number of times,
BUT.....
How can I get the mouse x,y of areas outside the client area? I tried doing
a captureMouse(MainWindow) but the system just hung with the wait cursor and
I had to ctrl-alt-delete out. I must be misusing the captureMouse. I put it
in a onMouse event=MOUSE_MOVE loop and then releaseMouse at end of the loop.
What I'm aiming for is to put little rectangles with text under the toolbar
that tells me what the glyph "stands for."
Thanks,
Judith

I'm in the middle of coding tooltips right now. I've got the structures
working, but they aren't responding. I'm not sure if I have to route events to
the tooltip structure, or what.
It's a lot of work to get some of these common controls working, and I'm really
not sure it's worth the effort - it may be easier to emulate the controls,
since I've already subclassed all the controls.
You shouldn't do a modal grab to get the mouse - this would cause too many
other side effects. The better way to emulate it would be to add some code in
the subclassed() loop, along with a timer. If the mouse has been sitting over a
control for a certain amount of time, pop up the tooltip. It is removed by the
mouse moving, a button being pressed, etc.
In any event, I hope to have tooltips for all controls working in a few days -
hopefully, without emulation.

Thanks David,
However, even with the captureMouse removed from the program the best I can
do is to trap y=34, which is the lowest value for y I can get and it is
right under the toolbar. If I place the mouse over the toolbar, onMouse
doesn't recognise it. Is that because the Toolbar sits over a portion of the
client area but is not accessable except to click? Anyway, I have it working
by drawing a little rectangle and depending upon the value of x, putting in
some text. As you would say, "not very elegant."
If you are addressing this I will just sit back and wait for it to be in
Win23lib.
As to my original question. IS there a way to get the mouse coordinates
outside of the client area?
thanks again,
Judith

Bother. But the controls *in* the toolbar should still respond to the mouse
event. That's the important part, since you want the tooltip to appear when
the mouse goes over the tool (button, combo, whatever), and not the toolbar
itself.

There are two ways I can think of doing it. The first is to convince Windows
to keep sending your program events, even when it's not in the client area.
Doing a modal grab works, but it has nasty side effects. The second is to
set up a timer in your window, and poll Windows to find out where the mouse
currently is. I suspect that approach is a resource hog.
But I'm not Windows guru. Any other suggestions?

This is the last beating I'm giving this old horse.
But the mouse doesn't recognise anything placed in the toolbar. Also in the
status bar.
Unless I have some subtle error.
I'm doing onMouse[Mainwin]= blahblah
and in that routine I have only if event=MOUSEMOVE. I trap x,y to new
variable names and force an onPaint.
the onPaint routine wPuts the x,y coordinates so I can see that only mouse
movements outside of the toolbar and status bar give me a value.
I was just curious about mouse outside of client area. I don't presently
have a need for it.

The toolbar is a window. I haven't tested this, but try doing an
onMouse[theToolbar] instead.

David: try onMouse[thetoolbar] instead
Tried it. No luck.
Anyway, I've taken up enough of your time.......
Thanks,
