What functionality in iReport allows for tool tip text?
I have a field name description that contains very large text. Instead of displaying large text I want to show two or three lines and rest of text as a tool tip. How is this possible?
回答1:
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.
