How can I immediately activate or deactivate tooltips for all TreeView

You can enable/disable all tooltips using the "gtk-enable-tooltips"
GtkSettings property.


I guess this works on all applications of the Gnome/GTK desktop?
Maybe not what the user wants...

But if you want to enable/disable them just for some specific of widgets
you have to handle it yourself.  The easiest method is probably making
the widgets query your enable/disable setting in their "query-tooltip"
signal handlers â and then return TRUE or FALSE from the handlers.

Thanks, this sounds good. I was not aware that this "query-tooltip"
handler is involved at all when I only use a simple
gtk_tree_view_set_tooltip_column()
(http://developer.gnome.org/gtk3/stable/GtkTreeView.html#gtk-tree-view-set-tooltip-column)

I will test it.

Best reagards,
