How to react on events fired by a JFileChooser?
843804Mar 29 2005 — edited Mar 31 2005Hello again.
I hava a FileChooser in my application to load an XML-file and then show its contents in a tab of a JTabbedPane.
When the user chooses a file and then clicks on the open-button of the dialog, I want to check if the file exists. In case of a non-existing file I want to show a modal MessageDialog with a corresponding message. During this time the file dialog must not close and stay open until the user cancels the operation or chooses an existing file.
What do I have to do to achieve this? I think I have to add an actionlistener and override the actionPerformed-method of the open-button. But how? Can you perhaps give me a little code example?
