The way to use Action Listeners is the same for any class. Re: Listeners 19 Years Ago by Phaelax I think you need to look at the Observer class. I'm not entirely sure how to use it, but it sounds like thats what you need. Re: Listeners 19 Years Ago by paradox814 why don't you make a method which assigns true instead of just declaring loggedIn = true; in other words [code]loggedIn = setTrue(); public boolean setTrue() { //do some stuff when the variable is set true here! return true; }[/code] Re: Listeners 19 Years Ago by server_crash I don't think you would have to use loops to continously check to see if it's true. I think you could just use some simple if statements or something simple to check if it's true. Paradox has a neat solution to it..Have a method that makes it true, and also can perform any other task you want if the boolean is true. If it were me, I would go … Re: Listeners 19 Years Ago by Black Knight i already have the set and get methods, the problem is the true bool is an attrib of the gui and you cant return values from a gui. so an if statement wouldnt work either, i need the main thread to watch the awt thread for the bool change and then shut down that gui and start another one. I think Phaelax was hitting nearer the mark with the … Re: Listeners 19 Years Ago by paradox814 ahhh... it's a gui component, well then just implement the appropiate listener. You should have said this from the beggining it's kind of hard to guess what you are doing. What component are you using? I will show you how to implement the appropiate listener if you do not know how to. Re: Listeners 19 Years Ago by jwenting Your component can fire for example a PropertyChangedEvent and your other class register itself with the component as a PropertyChangeListener (or whatever it's called). Needs a bit of code, but I'm sure most decent books and the Java tutorial have ample examples. Re: Listeners 19 Years Ago by Black Knight well in i want the main thread to basically wath the gui it creates and as soon as the bool in the gui flips to true i want it to dispose of the log in window and open the main app window, i have tried to implement propertychangelisteners and changelisteners etc... to no avail, i did have it creating the main window through the login listener but … Re: Listeners 19 Years Ago by Black Knight I think i will look further into propertychangeevents fireEvent() and custom Listeners 14 Years Ago by peter_budo … void removeCountListener(CountListener c){ if(listeners.contains(c)){ listeners.remove(listeners.indexOf(c)); } } public …catch(Exception e){ } } } } } public CountTest(){ listeners = new ArrayList(); } public void count(int i){ fireEvent… Re: fireEvent() and custom Listeners 14 Years Ago by JamesCherrill … the standard pattern: [CODE]ArrayList<CountListener> listeners = new ... ... void fireCountEvent(int count) { for (CountListener … . countEvent(count); } } ... void fireMultiplyEvent(int mult) { for (CountListener cl : listeners) { cl . multiplyEvent(mult); } } public void count(int count) { ... fireCountEvent(… Re: fireEvent() and custom Listeners 14 Years Ago by JamesCherrill …'s a danger of a problem if the list of Listeners is updated while the fireEvent code is looping through it…]ArrayList<CountListener> safeCopy = new ArrayList<CountListener>(listeners); for (CountListener cl : safeCopy ) { cl . countEvent(count); }[/CODE… Re: fireEvent() and custom Listeners 14 Years Ago by kvprajapati …ArrayList<CountListener> safeCopy = new ArrayList<CountListener>(listeners); for(CountListener c:safeCopy) { if(c!=null) c.countEvent(…ArrayList<CountListener> safeCopy = new ArrayList<CountListener>(listeners); for(CountListener c:safeCopy) { if(c!=null) c.countEvent(… Re: fireEvent() and custom Listeners 14 Years Ago by JamesCherrill I like the solution with a custom event class to carry the info to the listeners. Very nice. Particularly good if there is any chance that there will be more functionality added later, because you can add more event sub-types without changing the formal definition of the listener interface and thus invalidating existing code. Re: Linking JButtons to key events through Key Listeners. 16 Years Ago by Ezzaral You don't show how you are attaching the listeners, but yes, it's a focus issue. The easiest thing …for you to do is define the actions for those listeners as small inner classes that extend [URL="http://java…"]AbstractAction[/URL].
