No button tooltips in JUCE Widgets Demo

General JUCE discussion

Thanks. But what I’m saying is that the code for the Widgets demo, i.e. the buttons page, shows tooltips in the code.

            auto db = addToList (new DrawableButton ("Button 4", DrawableButton::ImageOnButtonBackground));
            db->setImages (&normal, &over, &down);
            db->setClickingTogglesState (true);
            db->setColour (DrawableButton::backgroundColourId,   Colours::white);
            db->setColour (DrawableButton::backgroundOnColourId, Colours::yellow);
            db->setBounds (400, 150, 50, 50);
            db->setTooltip ("This is a DrawableButton on a standard button background");
            db->onClick = popupMessageCallback;

But hovering the mouse over any of these buttons never shows a tooltip. The code implies the existence of tooltips, but I don’t see them. I’m looking for an example of how to implement.
