Catch the onCancelled event, and treat as "close" button tap. Also
disable cancel via taps outside the alert, which I think is less
confusing than leaving the unplayable game up without the alert or
closing it without explanation.
BoardDelegate can have a one-to-one relationship to this thing, and
occasional leakage was preventing opening a new alert, so some fix was
needed. This one's simple.
Because I'm doing a singleton thing, if I miss the alert going away I
won't up another up. This tries to always catch dismissal. Might still
be screwed if it's not actually put up for some reason. Needs testing.
Try using both secure and insecure sockets. The latter appears to cause
fewer problems on OS/device combos with crappy BT. It's only possible if
I know the addr of the device I want to, so hack around that being
secret by passing it on request.
If inviting known players to a more-than-two-player game, can select all
at once. Required using checkboxes instead of radiobuttons for the case
where nMissing > 1.
Create new class that owns the alert. Let it decide whether to post,
remove, etc. Seems to work, but I've removed some of the "reinvite"
options I'm not sure were helpful anyway. To be considered...
When thumbnail was required but couldn't be produced list item showed up
tiny as height followed thumbnail's. Instead, when there's no thumbnail
behave as if it's disabled, a layout that looks ok.
There are ways I can't record a close, e.g. user swiping app to kill
it. To avoid that leading to a corrupt-game warning, or to failure to
open in background, drop the count to 0 rather then merely decrementing
it when it closes correctly. Assumption is that if it closes ok once
it's ok.
Invitations over MQTT were handled by different code that always opened
the new game on top of any other open one. Use instead existing code
that puts up a notification instead where appropriate.
