JfileChooser

[Steve Howerton]

Hello . I have a desktop app the via Jlist I attempt to open files I placed in
the windows file system. I can manipulate the JFileChooser Dialog enough to
dispaly the files in the dir that I wish to open. However,when I click open nothing
happens. I am running my app using Netbeans and have yet to jar the app and run it
alone. I noticed that in another application that is running without neatbeans that when I use The JfileChooser it displays a Windows window (FileChooser) and the files
can be opened normally. My application in Neatbeans displays a JfileChooser that
does not look like the windows system FileChooser.

How can I open my files with this JfileChooser running in Netbeans?
When I select the .txt file to open it does not open it . it will show the JFileChooser again. see output : thanks
I need to open NotePad.txt files and .doc files with word!
thanks

What do you mean by "open" the file?

Do you want to display its contents in your Java app?

Do you want to open the file in the application that's bound to the file extension? E.g., if the user clicks a .doc file, open that in Word?

Something else?

If you read the docs for JFileChooser, I suspect you'll find that its job is only to present a graphical widget in which to select a file or directory, and then return to the caller which file or directory was selected. I doubt it says anything about "opening" the file.

At the time I wrote the question I did not see the difference. Thank you for pointing out what it is I actually need to do. I would love to be able to have the file selected in the JFileChooser. My DesktopApp button action Knows where the file is. Depending on the button it will know it should be looking for a the .txt or the .doc extention.

I would prefer to write the universal class not dependent on the event but to have java tell the operating system to open the file using a program dependent on the extention. Then I will be able to open *.txt with notpad and .doc with Word. at least. To open other extentions would be awesome though.

That's what the java.awt.Desktop class is for.

did not know that . way cool I am on it. Do you have some leads on some professionally written code examples?

I won't speak for everybody but in the day I would have been fired for sharing any proprietary code. I can't even see MY OWN code from that company any more.

Your best bet is always a good search engine to jump start it and then see where you run into problems.

It is because you are using the default Java's look and feel. Switch to system look and feel and the dialog will look like Windows dialog.

Have a look at the Desktop.open() method.
