Suppressed: Returns the component the tooltip applies to. The returned value may be null.

Returns:
the component that the tooltip describes
See Also:
JComponent.createToolTip()

alwaysOnTop

boolean alwaysOnTop()
Always returns true since tooltips, by definition, should always be on top of all other windows.

Overrides:
alwaysOnTop in class JComponent
Returns:
always returns false

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException
See readObject and writeObject in JComponent for more information about serialization in Swing.

Parameters:
s - the ObjectOutputStream in which to write
IOException

paramString

protected String paramString()

Overrides:
paramString in class JComponent
Returns:
a string representation of this JToolTip

getAccessibleContext

public AccessibleContext getAccessibleContext()
Suppressed: Gets the AccessibleContext associated with this JToolTip. For tool tips, the AccessibleContext takes the form of an AccessibleJToolTip. A new AccessibleJToolTip instance is created if necessary.

Specified by:
getAccessibleContext in interface Accessible
Overrides:
getAccessibleContext in class JComponent
Returns:
an AccessibleJToolTip that serves as the AccessibleContext of this JToolTip
