Vadim Zeitlin 7e8fb1e294 Use border style consistently in the widgets sample
Use GetAttrs().m_defaultFlags everywhere when creating the widgets, it
was done for some but not all of them before, without any apparent
reason.

This should make setting various border styles work (for the widgets
supporting them).
