dwindows: android/dw.cpp comparison

comparison android/dw.cpp @ 2510:f54051c3f2a5

Android: Implement MLE functions. Fix issues with checkboxes and sliders. Started enabling all notebook tabs in the test program... but a number of controls still missing, so functionality is still spotty at this point.
