Popup JInternalFrame not doing what it's supposed to when minimzed.
There are a ton of parts to this as different parts of the class cause different things to happen. I'm in the process of trying to create a way to reuse code. I was trying to get a tab to go to a popup internal frame when I clicked on a popup menu, which I'm also having some issues with, and it comes out like it's supposed to, but when I minimize it, my InternalFrameListener on the minimizing part isn't doing what it's supposed to. It isn't adding it back.
I had hoped to add it back where it was taken from (i.e. the spot) but it kept writing over other tabs and so I moved it (for now until I can find a method to add it with the stuff I want a special index but only insertTab() seems to work, and I can't get that to do what I wanted it to, and it now stops trying to add the JLabel for the addTab button and throwing a ClassCastException, it still won't add it back. It just minimizes the popup internal frame. (Ideally, I'd like it to keep the tab but just set another tab (or index -1 if necessary) to be selected. (Kinda like how JGrasp does its tabs.)
No, I cannot break this into a few lines. I could spend hours and hours working to whittle it down but there are many parts to this. And NO, I WON'T make it into a few lines stupid SSCCE. I tend to hate those but anyway, I can show the areas that are likely to affect it. Another reason I want to post all of it is that if I mistakenly remove something valid, somebody will whine "It won't compile." and I've had a lot of pain with that too and getting help in the past. A SSCCE won't really work in this case as there could be lots of areas that mess it up. I had an issue earlier that was glitching in an area I didn't even think would be affected by my code.

Also, this is another issue, how to stop the popupMenu from "sticking" the first time it comes up. (Also how to make sure it doesn't come up if you click the "+" button. I also would like it not to even show the background component if the "+" button is selected with the left click.)
tabPane.setComponentPopupMenu(tabPopupMenu);
Was I supposed to make it the component popup menu or was that a bad move and the reason it's sometimes sticking and not going away when released.
There's tons of areas.
