Forum: wxRuby layers

Is there a way to stack windows in Z dimension? I find that quite useful 
in
Android, and it would be useful here. I don't see it in the docs or the 
C++
book, so perhaps it's a wish list item.

For example, I have a gauge to display with a moving dial pointer. Due 
to
the fact that the pointer crosses several colors, simply "un-writing" 
the
pointer before moving it will not work, so I need to redraw the 
underlying
gauge which often hiccups even on my 4-core Ubuntu system.

If sizers could stack in Z, the top pane would be transparent except for 
the
dial pointer and it would be the only thing redrawn.

I haven't used them yet , but there are two methods that control the
z-hierarchy of a window.
Window#bring_to_front and Window#send_to_back.

I suspect that that refers to the window / frame relative to the window
manager hierarchy, the OS.  What I want to do is to stack panels  inside 
a
sizer such that they overlap. I haven't seen anything on that.

It seems that you're right.
Window#bring_to_front and Window#send_to_back correspond respectively
to wxWidgets Window#raise and Window#lower. The methods have been
renamed for consistency and to avoid name conflict with Kernel#raise.
And raise and lower work only for top level windows (see
http://trac.wxwidgets.org/ticket/4717).
According to the ticket, overlapping windows/controls are not advised.
Unfortunately the wxWidgets documentation has not been updated
accordingly 
(http://docs.wxwidgets.org/stable/wx_wxwindow.html#wxwindow).
Regarding wxRuby, I'll fix the documentation to clarify this point.

Cheers,

Yes, it does appear to be a design decision. Very useful 'would be 
nice',
though! :D

Thanks, Chauk-Mean.
