I've gotten some excellent follow-on requests, and I've explored several of them. While I may never have the time to implement them all - and some wander FAR from the original goals - some just fit. One of those ideas was for timed dialogs.
Enter the timed dialog. Drawing inspiration from the aforementioned mail notifications and a sample game by colleague Angela Caicedo, I expanded upon Angela's game-switching example to create a (hopefully pleasing) dialog fade in/out effect. Using the number of seconds specified by the developer (you!) via the method setDisplayTime(int displayTime), MonologFX apportions a reasonable percentage of that time to fade in, display, and fade out operations...making user input entirely optional.
It's much easier to demo than it is to explain, so I created a quick video of a normal dialog, then a timed one, in action. Click here to watch it on YouTube.
So for the foreseeable future, timed dialogs are really focused upon and should be confined to use as informational dialogs. If you need the application user to make a conscious choice prior to proceeding, keep that dialog prominently displayed until you get a response!
I've already pushed the code to my Github repository for MonologFX and the JFXtras-Labs 2.2 and JFXtras-Labs 8.0 repos. And if you just want to download a .jar file and kick the tires, I've put a copy in the MonologFX repo's dist folder. Just download the .zip file, unzip it, and run java -jar MonologFX.jar for a quick demo.
I also made a few architectural changes to MonologFX this weekend during our first-ever "Thanks For Sharing Informal, International HackFest", and more will be integrated over time. Please stay tuned for more information. :-)
