The problem with you code is that your radio buttons are defined as both class and local variables. Now from the command you you can test the applet just by using: YOu can add the following line of code to the top of your source file: Or I find it easer to test the applet without even creating an HTML file. How do you know you the ItemListener code isn't being invoked? Did you add a (.) statement to the listener code? Test your code first using the 'appletviewer'. Your question is about an ItemListener, so why did you post code related to a MouseListener and a MouseMotionListener? What does the custom painting code have to do with your problem? Sorry to anyone reading this but because it was homework I'm not 100% sure I can keep the code up, PM me if you need help understanding it! Below are examples of how I'm calling my radiobuttons, adding them to the shapes buttongroup, and adidng the buttons to the container c. This is for a homework problem and if I could use an actionperformed and actionlistener I would :(. I noticed that it requires two clicks to select a button, and hope that a problem lies within that. My combobox is also using the itemlistener interface and it works, but no matter what I've tried I can't get the buttons to send information/fire. So on the applet I can click on a button, but it won't fire. Currently everything works except for my JRadioButtons which doesn't call the itemStateChanged() when a button is selected. JRadioButton itemlistener not firing Hello my Japplet is using a JComboBox and 5 JRadioButtons to draw and paint on the applet. Use the ActionListener class and the buttons addActionListener() instead since you only need to know if the button was pressed or not. Window w = SwingUtilities.windowForComponent(Component c) The common use is to let buttons and menus share the same handler, but one Action can forward an event to another, as shown here for buttons and keystrokes. You might look at Action as a way to expose the desired functionality. In your nested classes and methods, in your case mouseClicked(). YourJFrame.getInstance().getPanels(10).sampleMethod() Take a look at Singleton examples on the web and you will be able to make a call like However this class has also its single static instance which can be referenced via getter method and used anywere in your code. In Singleton pattern, the constructor of the class that we apply the pattern is private, so you cannot make instances of it. Anyway, you can use Singleton design pattern in your application to get and use the same instance (in your case the same main instance) anywhere in your code. The main window class instance? It seems you have only one instance of your main window which may extend JFrame or JPanel or JDialog etc. So, how do I get the main window instance, so I could get that panel list, get the specific panel and run SampleMethod with this instance?ДЄs panels are added to some sort of list in the main window class As panels are added to some sort of list in the main window class instance, I just made it public, and want to access it in mouseClicked event of the button.

Swing - get main window class instance from button class I need to run a method (lets call it SampleMethod) in a panel class upon the click on specific button. Of course, this is all conjecture without seeing some actual code :) When the button inside the JFrame needs to notify the controller it should be able to call some getController() method. Then when you create an instance of the JFrame from the Controller you pass it a reference to itself using the 'this' keyword. I'm happy to post code if necessary, but it's more a problem of 'how do I do this?' than fixing something that is broken.Д®xtend the JFrame with your own JFrame, which has an overloaded constructor that takes an instance of the Controller. Basically, I want to add a button into the JFrame that will call a method in the controller class when clicked.

I'm kind of stumped as to how to accomplish this. Now, I want to add a button into the JFrame that signals the controller I want to 'move on' the simulation. When I run the project, the main makes a controller, which makes a JFrame. In the controller cass I have an object of the JFrame class. In the main class and method, I have an object of the Controller class. Long story short, (among others) I have a controller class and a JFrame class.

I'm pretty far into it, but I came across a problem I haven't had before. Firing a method in my Controller class from a button in my JFrame class So I'm doing a project for school where I'm supposed to simulate a supermarket.
