I'm closing all MMapMagnets (kind of property TopComponents), that should
only be visible when the MapTopComponents is with
final WindowManager windowManager = WindowManager.getDefault();
windowManager.getModes().stream().filter((mode) ->
!(mode.equals(windowManager.findMode(this)))).forEachOrdered((mode) -> {
TopComponent selectedTopComponent =
mode.getSelectedTopComponent();
for (TopComponent tc : mode.getTopComponents()) {
if (tc instanceof MTopComponent && tc.isOpened() &&
!windowManager.isTopComponentFloating(tc)) {
if (tc instanceof MMapMagnet) {
if (tc.equals(selectedTopComponent)) {
mActiveMapMagnets.add(tc);
}
tc.close();
mMapMagnets.add(tc);
}
}
}
});
In short, use the WindowManager and Modes.
And in context, no pun intended.
