Clicking on the arrow when the menu is already open should close it.
it seems vstejskal already fixed this
Yes, sorry, I didn't know about this issue. I also changed the way how the arrow
is added to the button's icon, the motivation was to make the default
implementation for greying out icons in disabled buttons work. This default
implementation applies GrayFilter on Image, hence it only works for ImageIcons.
Regarding ImageIcon, I filed issue #104530.
The same for DropDownToggleButton.
Checking in DropDownToggleButton.java;
