Unable to reference String variable within mouseAdapter class
Hi
I am writing a java bean for use with an Oracle form. The bean colours a text item on the screen on mouse rollover. I would to suppress the colour change based on the value of a property set in the form. To implement this I have included a check on String in the mouseEntered method.
I would like the default behaviour to be rollover enabled. However if I don't set the property from the Oracle form my String value is set to "false"
When the property is set from the Oracle form the setProperty method is invoked
How can I set the default value?
