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

object -- a gtk-icon-view widget
column -- an integer, which is a valid column number for icon-view's model

Accessor of the tooltip-column slot of the gtk-icon-view class.

The slot access function gtk-icon-view-tooltip-column returns the column of the icon view's model which is being used for displaying tooltips on the icon view's rows. The slot access function (setf gtk-icon-view-tooltip-column) sets the column.

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 argument column 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 function gtk-tooltip-set-markup, so &, <, etc have to be escaped in the text.
