This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
Hi all, Would you please tell me how to let a JFileChooser only accept one file type for example "*.jar"(I know FileFilter). In fact, I don't want that user can select "all files" in JFileChooser, but I don't know how to disable the JCombobox. Thanks ahead!
