Nit: Consider adding children in response to this object itself being added to a
view hierarchy; this is the typical pattern in views and it avoids the need to
allocate anything if for some reason you're constructed but never put in a
hierarchy.

[yefimt, 2012/07/18 23:18:13]

Done.

[Peter Kasting, 2012/07/18 01:37:25]

If you're trying to manage the |button_| lifetime yourself, omit this line and
instead use set_parent_owned(true) when you add the button as a child.  This is
not only clearer about ownership, it prevents problems if for some reason
someone else removes the button as your child.

[yefimt, 2012/07/18 23:18:13]

Apparently it is owned by parent by default.

[Peter Kasting, 2012/07/19 04:27:31]

I'm sorry, I misspoke: set_parent_owned(false).  The difference between the two
is rather critical :)

[Peter Kasting, 2012/07/19 04:42:35]

Ah, as Thiago points out, the name of this has apparently changed -- it's now a
zero-arg "set_owned_by_client()" call.

Is explicitly giving the scale as 100 correct?
