No, the docs are correct, I forgot about using actions in toolbars. :P

Native Windows menus don't support tooltips, Qt menus don't use tooltips, Gtk+ menus don't use tooltips. I thought it's standard menu behavior, isn't it?

Toolbars can be shown in "icons only" mode and in that case tooltips are the only way of showing the button's brief description. What's the purpose of tooltips in menus? Brief description is the item's label itself, detailed description can be displayed in status bar (http://qt.nokia.com/doc/4.6/qaction.html#statusTip-prop).
