HI, All
One my B4J app uses key listener as many times shown on the forum.
But now i have copy-pasted the code to another app - and it does not work fully - no event.
The same code as usual:
Tried and r.AddEventFilter with correct event sub name updating - also no help.
Libs JavaObject and Reflection are included OK, no any errors.
App uses also MenuBar and EventFilter for mouse events (later in the class), but if to remove them for test - no help anyway.
But no "_Event" triggered.
What trick may be forgotten from 1st app where works OK ?
