Mac OS X Java Swing Buttons are Disabled for no aparent reason

Question

I wrote an application in Java and when it runs on one customer's computer running OS X The Save and Export buttons are disabled. (Everything else works in the application.)

Both of these buttons open up a standard save file dialog.

Any ideas?

Answer 1

The fact that these buttons open a file dialog probably has nothing to do with it being disabled. Buttons can end up being disabled for a number of reasons,

• its setEnabled can be called with false,
• when using an action, its setEnabled can be called with false, and
• when using an action, it can have a property "enabled" that potentially disables it; see Action for more information, there's a list of properties there.

Could you post how you 'implemented the JButtons'?

Answer 2

A stab in the dark, but most macs are still running Java 1.5; check if your current code misbehaves with Java 1.5 on your end. Maybe that's where you problem lies.

Answer 3

This was caused by misinformation recieved from the customer.

Turns out the customer was trying to save to a location where files can't be saved on his/her hard drive.
