{do } versus plain code expression - RobertShiplett - 05-31-2012
Today I was working inside a PlainDocument and added a second loop to pass through some data.
Between the two loops, I decided to place a blank row of empty strings.
So I dropped in some code to do just that between two {for } iterator expressions.
Boom! Busted applet. Could not add my Visual to a PlainDocument which already held an object.
Hmmm ....
And there it was: adding a row-prototype to that table was returning a value !
Answer: wrap that expression in a {do } expression.
Bong ! Working applet.
You can see the result at http://www.aule-browser.com/kanji/poets/basho-ka-ume.html
and there a few rows down is that blank row ...
And, yes, this is a PlainDocument ... the links at the bottom of the page are in the HTML wrapper ... for now.
