With the PopupMenu creating its own window the focus would return to the
ComboBox after activating a menu item. Prior to this commit however the
focus was seemingly lost after menu item activation. With this change
the focus returns to the ComboBox in both cases.

Prior to this fix gradually changing the Component scale would lead to
the jittery movement of drawn bitmaps, as their position would be
snapped to an arbitrary integral representation.
The issue became manifest in c51b331318.
In our implementation the toggle action takes precedence over the press
action, making the latter unreachable when the Item is in a checkable
state. Calling isTicked (true) turns the Item into a checkable object.
The onToggle implementation however didn't interact with the isTicked
state, and it didn't fire the press action either. This made the item
non-interactable with screen readers once it got into a ticked state.
This bug could be observed in the DemoRunner:
- Enable "button" navigation mode (as opposed to "gesture" mode) on the
Android device.
- Remove the line enabling kiosk mode, build and install the DemoRunner.
- Run the app and navigate to the Settings pane. Open a menu, or the
bluetooth MIDI dialog window, then close the popup window.
- Rotate the device.
Previously, the steps above could result in the system painting its own
backgrounds behind the system bars. With this patch in place, we reset
the requested system UI colours and transparency, which seems to
maintain the desired appearance.
A recent change made disabled components traversable by default when
using a screen reader. This change makes TalkBack report such components
as disabled.
With this change disabled components become discoverable by screen
readers, similarly to how OS native user interface components behave by
default.
The KeyboardFocusTraverser will still skip disabled components so this
does not affect keyboard navigation without screen readers.
handlePositionChanged() is called when the window changes z-order, which
may cause a new mouse event to be synthesised if the mouse is over the
window after the z-order is updated. In this situation, we may not have
received a mouse up/down/move event to update the current modifier
flags, so we need to update them ourselves.
This addresses an issue where OpenGL-backed image content could get lost
when putting and Android app into an inactive state. This happens
because the GL context gets destroyed, freeing all associated resources.
The workaround introduced here will listen for OpenGL state-change
events, and attempt to save and restore framebuffer content into main
memory, so that the content can be restored once the app is reactivated.
This reimplements similar functionality to that removed in
d39789b021.
Unlike the previous implementation, this version will still wait for the
mouse to move over the menu before the countdown timer is allowed to
start. This should avoid the situation where menu items are accidentally
triggered on mouse-up, after a menu opens under the pointer in response
to a mouse-down.
ComponentPeer::setAppStyle() will now update the status and navigation
bar foreground colours, with some caveats:
- Status and nav bar backgrounds are now always completely transparent.
- The navigation bar foreground colour can only be changed on Android
API 26 or higher.
- For platforms using gesture controls instead of button controls, the
system automatically determines the colour of the gesture bar. On
those systems, setAppStyle() will only affect the status bar colour.
