37 |
* <p>
|

38 |
* ToolTipManager contains numerous properties for configuring how long it
|
|
39 |
* will take for the tooltips to become visible, and how long till they
|
|
40 |
* hide. Consider a component that has a different tooltip based on where
|
|
41 |
* the mouse is, such as JTree. When the mouse moves into the JTree and
|
|
42 |
* over a region that has a valid tooltip, the tooltip will become
|
|
43 |
* visibile after <code>initialDelay</code> milliseconds. After
|
|
44 |
* <code>dismissDelay</code> milliseconds the tooltip will be hidden. If
|
|
45 |
* the mouse is over a region that has a valid tooltip, and the tooltip
|
|
46 |
* is currently visible, when the mouse moves to a region that doesn't have
|
|
47 |
* a valid tooltip the tooltip will be hidden. If the mouse then moves back
|
|
48 |
* into a region that has a valid tooltip within <code>reshowDelay</code>
|
|
49 |
* milliseconds, the tooltip will immediately be shown, otherwise the
|
|
50 |
* tooltip will be shown again after <code>initialDelay</code> milliseconds.
