Need image to update with JComboBox selection

Question

hello, i have code here that loads an image from a JFileChooser dialog when "Add Image" is clicked, the images name and path is stored in a JComboBox, and the image name is displayed. As more images are added to the JComboBox, I would like to be able to have the picture displayed in concurrence with whatever image is selected from the comboBox. For instance, if Jessica.jpg is selected in the JComboBox, i need Jessica.jpg to be loaded into imagePanel. Here is the code. The problem lies within the JComboBox's "itemStateChanged" I believe... This is what must be used (i think) to update the pictures in the imagePanel when the combobox is manipulated....

Answer 1

You don't really expect us to read through 300 lines of code do you?
If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
And don't forget to use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags so the code retains its original formatting.
In the meantime I suggest you read the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/combobox.html]How to Use Combo Boxes for a working example that does exactly what you want.
