Getting a filename from the WidgetSelected method [message #1829546]

I created a handler class for my eclipse plugin. Currently, I have a window pop that pops up which contains a button. That button, when clicked, opens a file dialog. I want to be able to in the main class of the handler, assign the fileName received in the WidgetSelected method to a String variable. I want to be able to display the fileName received in the window as a textbox. Is there a way to do this without making the fileName a global variable?

If you're just trying to make the value visible outside of the scope of your anonymous SelectionListener, there are multiple ways to do it. The simplest, and you'll see this done in a lot of Eclipse code, is to create a final array with a length of 1 and have your listener store the value inside the array.
