Tooltip for search dialog elements.

I would like to add tooltips for the buttons and checkboxes in the search dialog. If the text of the buttons and checkboxes doesn’t fit the dialog, I use ellipses, and I need a tooltip to show when I hover over the buttons or the checkboxes. Is there a way to implement this?

The only way to adjust the way the search panel is rendered is to override it completely via the createPanel option.
