gtk:icon-view-tooltip-column (object)

object -- a gtk:icon-view widget
column -- an integer that is a valid column number

The accessor for the tooltip-column slot of the gtk:icon-view class gets or sets the column in the model containing the tooltip texts for the items.

If you only plan to have simple (text-only) tooltips on full items, you can use this function to have the gtk:icon-view widget handle these automatically for you. The column argument should be set to the column in the icon view's model containing the tooltip texts, or -1 to disable this feature.

When enabled, the has-tooltip property will be set to true and the icon view will connect a "query-tooltip" signal handler. Note that the signal handler sets the text with the gtk:tooltip-set-markup function, so &, <, and so on, have to be escaped in the text. The gtk:icon-view implementation is deprecated since 4.10. Use the gtk:grid-view implementation instead.
