Getting quite close. Buttons (menu items), checkboxes, radio buttons, and
button groups are all working with proper event handling (FYI, event
handling requires jQuery >1.7, which JSmol appears to be using, but just a
heads up for those who might wish to "downgrade" jQuery for some reason.
Hope this is OK).
Figuring out when exactly to bind handlers to click and change events was a
little tricky, but I think I've got it down. It happens in the
PopupMenu.addItem and SubMenu.addItem functions, after the HTML of the item
has been added to the page's DOM. I think this is a little different from
the way addItemListener and addActionListener work in Java...but the same
effect is achieved.
Some questions that remain:
- What's an ImageIcon? Could I get an example in the current context menu
for Jmol (Java)? Same question for AbstractButton and JComponent. If my
poor memory of Java serves me right, JComponent is a very "low-level" class
in Swing. Once those three are implemented, all the objects you listed will
have JS equivalents, Bob.
- Still not seeing how to wire my setup to the
org.awtjs2d.Platform.getMenuPopup function. I dig into Platform.js and all
I see is a line of code that sets the function to null...*Nevermind, I have
an old version of JSmol on my server :-D* Still don't really see how to
actually call that function and use what it returns, though. Can't find it
in the Jmol object or in the applet's instance object.
Cheers, Mike
