javax.swing.ToolTipManager
Manages all the ToolTips in the system.
ToolTipManager contains numerous properties for configuring how long it
will take for the tooltips to become visible, and how long till they
hide. Consider a component that has a different tooltip based on where
the mouse is, such as JTree. When the mouse moves into the JTree and
over a region that has a valid tooltip, the tooltip will become
visibile after initialDelay milliseconds. After
dismissDelay milliseconds the tooltip will be hidden. If
the mouse is over a region that has a valid tooltip, and the tooltip
is currently visible, when the mouse moves to a region that doesn't have
a valid tooltip the tooltip will be hidden. If the mouse then moves back
into a region that has a valid tooltip within reshowDelay
milliseconds, the tooltip will immediately be shown, otherwise the
tooltip will be shown again after initialDelay milliseconds.

public void setLightWeightPopupEnabled(boolean aFlag)
JToolTip, the
ToolTipManager chooses to use a lightweight
JPanel if it fits. This method allows you to
disable this feature. You have to do disable it if your
application mixes light weight and heavy weights components.

initialDelay milliseconds before a tooltip will be
shown. That is, if the tooltip is hidden, and the user moves into
a region of the same Component that has a valid tooltip within
milliseconds milliseconds the tooltip will immediately
be shown. Otherwise, if the user moves into a region with a valid
tooltip after milliseconds milliseconds, the user
will have to wait an additional initialDelay
milliseconds before the tooltip is shown again.

ToolTipManager objectpublic void registerComponent(JComponent component)
This will register key bindings to show and hide the tooltip text
only if component has focus bindings. This is done
so that components that are not normally focus traversable, such
as JLabel, are not made focus traversable as a result
of invoking this method.
