Advanced Java: Swing (GUI) Programming Part 5 -- Event Handling
Descripcion del Video
Complete course: /java-swing-compl... A tutorial on how to implement custom events and how to deal with events generally in Java Swing applications. This tutorial shows you how to wire up your Swing app, so that the different parts of the application can communicate with each other using events routed through a central controller object, helping to prevent your app becoming a rat's nest.

Hi how would you go about using a button to open up a new jpanel and disposing of the old one with the set up you have here. Ie first diplay has a button that goes? to second display and first display is disposed of. Do you cover this in you paid swing tutorials also can you down load them. To reduce data cost if watchin same vid over and over.
I cover various options along these lines in? the full course. Yes, you can download the course if you subscribe too. Best way is to use a CardLayout to switch views. You could alternatively just create a new window and set the old one to invisible, but best practice is to stick with one window and just change the view in it.
Im not the best programmer in the world, as i know basic c++, C.net, most web application programming, but i just don't understand what your doing essentially with creating your own object listener. Assume, i'm using notepad (cause i am). This is my interpretation after reading your code.. Your Calling the action that occurred inside the details panel so? your class can interpret the input into the textfield on the east? If that's correct-
Hi Richard, I'm not sure if that's a good description of it or not. The stuff I go through here is known as the "observer pattern" --- it you look at my channel, you can find three videos on it that break it down a lot more than this video. This video also goes over some unnecessary detail really -- it was my first stab at explaining this. The thing is that if you call one components's methods from another, those two components are permanently? intertwined, and not very reusable.
I didnt get why you? cast in the if statement ?
getListenerList() just returns objects of type "Object". But these objects are really various kinds of listeners, depending on what you added to the list. So you have to cast to the correct type so that you can call specific methods of the particular type of listener. Mind you, I keep meaning? to remake this video ... it would be simpler not to use this listener list thing at all but just to use a reference to the listener.
I just want to say? thank you so much for this. It really helped me out of the rough patch I've been on. One can only go so far with a trial and error method. xD
In this app that would be fine, but as your program grows in complexity, it tends to become unmaintainable. So the idea is to? try to route all events through a central place. Having said that, this video tries to fit in much too much to 15 mins and the solution I present is overkill in the context ... I intend to remake it very soon, giving a variety of solution.
Perfect Swing Series exactly what I've been looking for. Clear and precise this? series will help me alot. Thx's
Okay, well i did what i said and it works and makes more sense to me to do. Is my way considered bad practice? Does calling a function back like that slow down? processing time? I believe my way keeps things a bit neater and file size down a little. is this fine?
Couldn't you create a separate function containing the function call of the event listener inside the details panel class and call details panel? an object in the MainFrame and call its function? I will subscribe, but can you explain absolutely everything without bouncing between class tabs? Great video's.
