Dialog.addCollapseListener(CollapseHandler) should be called addCollapseHandler(CollapseHandler)

[mP1]

IM using a Dialog and i wanted to know when the user closed a dialog via ESC etc.

My code had a fragment similar to

Dialog.create()
  .addCollapseListener(this::onClose)

But my onClose was not being called.

Turns out there are two overloads:

• addCollapseListener(CollapseHandler)
• addCollapseListener(CollapseListener)

My bad luck was i thought the compiler was passing my method reference to Dialog.addCollapseListener(CollapseListener) , but i was actually registering a CollapseHandler to Dialog.addCollapseListener(CollapseHandler) and CollapseHandlers are not fired by Dialog.close/onClose.

The old interface have been deprecated and a new interface with more accurate naming is added, instead of expand/collapse now uses Open/Close.
