ToolTipManager (Java Platform SE 8 )

java.lang.Object
- java.awt.event.MouseAdapter
- - javax.swing.ToolTipManager

All Implemented Interfaces:

MouseListener, MouseMotionListener, MouseWheelListener, EventListener
```
public class ToolTipManager
extends MouseAdapter
implements MouseMotionListener
```
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 visible 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.

- Method Detail
  - setEnabled
```
public void setEnabled(boolean flag)
```
    Enables or disables the tooltip.
    
    Parameters:
    
    flag - true to enable the tip, false otherwise
  - isEnabled
```
public boolean isEnabled()
```
    Returns true if this object is enabled.
    
    Returns:
    
    true if this object is enabled, false otherwise
  - setLightWeightPopupEnabled
```
public void setLightWeightPopupEnabled(boolean aFlag)
```
    When displaying the 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.
    
    Parameters:
    
    aFlag - true if a lightweight panel is desired, false otherwise
  - isLightWeightPopupEnabled
```
public boolean isLightWeightPopupEnabled()
```
    Returns true if lightweight (all-Java) Tooltips are in use, or false if heavyweight (native peer) Tooltips are being used.
    
    Returns:
    
    true if lightweight ToolTips are in use
  - setInitialDelay
```
public void setInitialDelay(int milliseconds)
```
    Specifies the initial delay value.
    
    Parameters:
    
    milliseconds - the number of milliseconds to delay (after the cursor has paused) before displaying the tooltip
    
    See Also:
    
    getInitialDelay()
  - getInitialDelay
```
public int getInitialDelay()
```
    Returns the initial delay value.
    
    Returns:
    
    an integer representing the initial delay value, in milliseconds
    
    See Also:
    
    setInitialDelay(int)
  - setDismissDelay
```
public void setDismissDelay(int milliseconds)
```
    Specifies the dismissal delay value.
    
    Parameters:
    
    milliseconds - the number of milliseconds to delay before taking away the tooltip
    
    See Also:
    
    getDismissDelay()
  - getDismissDelay
```
public int getDismissDelay()
```
    Returns the dismissal delay value.
    
    Returns:
    
    an integer representing the dismissal delay value, in milliseconds
    
    See Also:
    
    setDismissDelay(int)
  - setReshowDelay
```
public void setReshowDelay(int milliseconds)
```
    Used to specify the amount of time before the user has to wait 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.
    
    Parameters:
    
    milliseconds - time in milliseconds
    
    See Also:
    
    getReshowDelay()
  - getReshowDelay
```
public int getReshowDelay()
```
    Returns the reshow delay property.

    See Also:
    
    setReshowDelay(int)
  - sharedInstance
```
public static ToolTipManager sharedInstance()
```
    Returns a shared ToolTipManager instance.
    
    Returns:
    
    a shared ToolTipManager object
  - registerComponent
```
public void registerComponent(JComponent component)
```
    Registers a component for tooltip management.
    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.
    
    Parameters:
    
    component - a JComponent object to add
    
    See Also:
    
    Component.isFocusTraversable()
  - unregisterComponent
```
public void unregisterComponent(JComponent component)
```
    Removes a component from tooltip control.
    
    Parameters:
    
    component - a JComponent object to remove
  - mouseEntered
```
public void mouseEntered(MouseEvent event)
```
    Called when the mouse enters the region of a component. This determines whether the tool tip should be shown.
    
    Specified by:
    
    mouseEntered in interface MouseListener
    
    Overrides:
    
    mouseEntered in class MouseAdapter
    
    Parameters:
    
    event - the event in question
  - mouseExited
```
public void mouseExited(MouseEvent event)
```
    Called when the mouse exits the region of a component. Any tool tip showing should be hidden.
    
    Specified by:
    
    mouseExited in interface MouseListener
    
    Overrides:
    
    mouseExited in class MouseAdapter
