I am trying to have a tooltip text on mouseover on Column Header or any type of text field in Jasper iReports.
I found a similar question which was not properly answered so i have to re-open it…
What i essentially need, is to show descriptive information of a column when user hovers his mouse pointer over the report in Jasper Server.
You can use hyperlinkTooltipExpression expression for textField element, for example.
You can find sample here.
In iReport you can call dialog for setting tooltip with help of context menu Hyperlink.
