Re: EventListener for sequence of events 17 Years Ago by taineechan Now that I have one eventlistener, how do I know which button is pressed? Is there something like an isClicked method? EventListener for sequence of events 17 Years Ago by taineechan Hi I'm coding a game of towers in java. I'm having trouble moving a stack from one button to another. I have eventlisteners for buttons A and B. If Button A is clicked and then button B is clicked, the value at button A must be added to the value at button B. <the values are text on the buttons> How can I achieve this? Re: EventListener for sequence of events 17 Years Ago by thekashyap Well you've gotta have some common place to store the values of these buttons.. So may be have a class (say my_container) to contain these values. Catch is both the button's handler classes must have access to same object of this my_container class. You can do this is with [URL="http://en.wikipedia.org/wiki/Singleton_pattern"]Singleton … Re: EventListener for sequence of events 17 Years Ago by masijade Well, if the instances of the Buttons themselves are known to the ActionListener (i.e. they are instance variables that the ActionListener has access to) you can simply use getText() to get the displayed value on the button.

If so you'll run into same problem. (both ActionListner objects have to know both Button objects). Instead on click of A, update the value in "common place" and on click of B pickup the value from "common place" and do the needful… Re: EventListener for sequence of events 17 Years Ago by taineechan I've put all my buttons into a 2D array and they use one listener. I'm gonna try the if statement and previous variable thing. I'll only try Singleton if that doesn't work coz I personally find design patterns a little scary. Thanks so much for the help:) Re: EventListener for sequence of events 17 Years Ago by thekashyap What's the type of listner you're using? (Class name) If you're using/registering a single listner object for both buttons' click event, you can do what masijade said.

If yes then you don't need any listeners to the radio buttons. Whenever a button is clicked, you can get the value of the radio selected and then with if statements select the set you want to … Re: EventListener on Choice Menu 14 Years Ago by bobinson Thanks a lot Javaddict,I do really appreciate your attempt to help.Here I'm including sections of my problem perhaps that would make things a a lot more clear My choice button were created thus [CODE=java] Choice travelChoice; travelChoice=new Choice(); travelChoice.addItem("A "); travelChoice.addItem("B "); travelChoice.addItem… Re: EventListener on Choice Menu 14 Years Ago by Ezzaral Just have an int[] array variable like "selectedFares[]" that points to the correct fare array.

Re: EventListener on Choice Menu 14 Years Ago by Ezzaral Let's say your fares were in an array [iCODE]fares[3][][/iCODE]. Then your option group index directly corresponds to a fare schedule[code]selectedFare = fares[optionIndex];[/code]No need for a switch. The rest of your code just references [iCODE]selectedFare[i][/iCODE].
