| |
| Listens to the native virtual keyboard for hide/show events and provides |
| hints to the OS for showing/hiding. On WinRT, showInputPanel()/hideInputPanel() |
| have no effect because WinRT dictates that keyboard presence is user-driven: |
| (http://msdn.microsoft.com/en-us/library/windows/apps/hh465404.aspx) |
| Windows Phone, however, supports direct hiding/showing of the keyboard. |
