[simonmorris, 2012/10/11 21:27:35]

Done.

nit: Add and explanation what this class is for.

[simonmorris, 2012/10/11 21:27:35]

Done.

nit: scoped_refptr?

[simonmorris, 2012/10/11 21:27:35]

I don't think a scoped_refptr adds anything here. The context getter has to
outlive this object, and it does so.

[alexeypa (please no reviews), 2012/10/12 17:09:35]

scoped_refptr provides a strong guarantee.

[simonmorris, 2012/10/15 16:51:41]

Done.

nit: sort the variables alphabetically. Add comments explaining what they are
for.

[simonmorris, 2012/10/11 21:27:35]

I don't think there's any general rule that variables should be sorted
alphabetically. These are sorted by role, and by visual order within the dialog
box, in the case of members that reflect widgets.

I've added a comment.
