Hi Tom and Lei,

Please start to review this CL. Thanks!

File xfa/src/fwl/src/lightwidget/checkbox.cpp (left):

https://codereview.chromium.org/1507683010/diff/1/xfa/src/fwl/src/lightwidget...
xfa/src/fwl/src/lightwidget/checkbox.cpp:20: prop.m_pOwner =
m_pProperties->m_pOwner->GetWidget();
These two assignments were in the helper function. Over there, m_pProperties was
tested. I am sorry for that my comment misled you.

LGTM.  I think this was originally right, but I botched it.  Thanks.
