TreeView.setTooltipColumn

void setTooltipColumn(int column)

If you only plan to have simple (text-only) tooltips on full rows, you can use this function to have [gtk.tree_view.TreeView] handle these automatically for you. column should be set to the column in tree_view’s model containing the tooltip texts, or -1 to disable this feature.

When enabled, GtkWidget:has-tooltip will be set to true and tree_view will connect a GtkWidget::query-tooltip signal handler.

Note that the signal handler sets the text with [gtk.tooltip.Tooltip.setMarkup], so &, <, etc have to be escaped in the text.

Parameters

column an integer, which is a valid column number for tree_view’s model

Deprecated

Use [gtk.list_view.ListView] or [gtk.column_view.ColumnView] instead
