Calculator - Bottom row buttons difficult to select in portrait mode

[Neil McPhail]

Calculator v 2.0.155 on krillin running RTM v 20

When in portrait mode, the bottom row of buttons (. 0 () =) are difficult to click as the "Favourite" drag bar becomes selected instead. I think there needs to be extra padding at the bottom to prevent this from happening.

What should happen: pressing '0', '.', '()' or '=' should register a button press.

What actually happens: The button is only recognised if the top few pixels of the buttons are pressed.

Solution:
DirectionalDragArea - new component which should be exposed with ticket:

This seems to be less of a problem in landscape mode on my device, but can still happen.

It's just as hard to select the bottom in landscape mode.

FWIW, there is a DirectionalDragArea in unity8 which is in the process to be transformed to an SDK component. That would pass clicks through and only intercept drags from the bottom. This is however still a bit down the road, so depending on how bad this bug is it could make sense to come up with a temporary workaround.

I'm not sure this bug should have had its description updated to mark a solution. The first comment on the DirectionalDragArea bug states that the browser app has already implemented a version of this component. The browser bottom-edge obscures the pixels on the same rows as the hint, in a similar way to the Calculator app. We probably need to see a working version of the component before marking this as a solution.

@njmcphail: You are right, the browser seems to be broken too in this regard, despite using the DirectionalDragArea. However, for a working implementation of the DirectionalDragArea, see unity. The DirectionalDragArea is used for the left and right edges.

For webbrowser-app, this is already being tracked by a separate bug report: bug #1474533.

[Michael Zanetti (mzanetti)]

Removing unity too as it is working fine there.

FWIW, the DDA will land in the SDK in OTA-9
