/**
A box with a small arrow that can be used as a temporary pop-up window to show
extra controls when a button or other component is clicked.
Using one of these is similar to having a popup menu attached to a button or
other component - but it looks fancier, and has an arrow that can indicate the
object that it applies to.
The class works best when shown modally, but obviously running modal loops is
evil and must never be done, so the launchAsynchronously method is provided as
a handy way of launching an instance of a CallOutBox and automatically managing
its lifetime, e.g.
@code
void mouseUp (const MouseEvent&)
{
auto content = std::make_unique<FoobarContentComp>();
content->setSize (300, 300);
auto& myBox = CallOutBox::launchAsynchronously (std::move (content),
getScreenBounds(),
nullptr);
}
@endcode
The call-out will resize and position itself when the content changes size.
