Pretty much.

I sort of started that way, putting the desired control and the
StaticText on a Panel, but then I had to figure out haw to get the event
binding right (not too hard), then I realized that I needed to get the
attribute resolution right, etc, etc. -- it started getting ugly.

I re-thought, and i realized that I don't really need them to behave
like a single widget in all ways -- only as far as layout is concerned.
So I made a factory function that creates a Sizer from an already
created control and the label text. It puts them in a BoxSizer, and
returns that. You can then drop that into another sizer like a single
object.

I've enclosed the code -- there's not much to it. It works for my needs
at the moment, but I think it might be worth making more robust and
complete in the future. I now it has greatly simplified my sizer layout
that I had for a bunch of wx.Choices in a FlexGridSizer.

The main issue I had was that I needed a different amount of space
between the label and the widget as I needed between the different
widgets. to accomplish this, I needed to put in columns that were just
spacers, it got ugly.

I've enclosed a png of what I have now. the issue here is that the
labels are sized independently, so they don't line up, but that works
for me here. I can't think of a way to fix that right now

I think so too, but I wasn't struggling with the sizer layout -- I was
struggling with the fact that I had a label and a widget that belonged
together, but putting them in a sizer didn't respect that. If I wanted
to switch around the layout (which I did), I needed to remember to move
the label, the widget, and the spacers.

That's close to what I had in mind, but I realized I'd be happier of I =

could make a generic one, rather than one for each type of widget I =

might need.

Let me know what you all think.
