Showing Multiple Lines in a Tool Tip
A tool tip can show simple HTML tags when surrounded by the tags
<HTML> and </HTML>. This example shows how to create
multiple lines by using the <BR> tag. See the
javax.swing.text.html.HTML class documentation for a list of
supported tags.
// Show two lines in the tool tip
component.setToolTipText("<html>"+"This is a"+"<br>"+"tool tip"+"</html>");
// By default, the lines are left justified. Center the lines.
component.setToolTipText("<html><center>"+"This is a"+"<br>"+"tool tip"+"</center></html>");
// Italicize the second line
component.setToolTipText("<html>"+"This is a"+"<br><i>"+"tool tip"+"</i></html>");
