ToolTipManager (Java 2 Platform SE 5.0) (original) (raw)

javax.swing

Class ToolTipManager

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

All Implemented Interfaces:

MouseListener, MouseMotionListener, 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 visibile after initialDelay milliseconds. AfterdismissDelay 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.

lightWeightPopupEnabled

protected boolean lightWeightPopupEnabled

heavyWeightPopupEnabled

protected boolean heavyWeightPopupEnabled

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, theToolTipManager chooses to use a lightweightJPanel 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 waitinitialDelay 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 withinmilliseconds 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.

Returns:

reshown 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](../../java/awt/event/MouseAdapter.html#mouseEntered%28java.awt.event.MouseEvent%29) in class [MouseAdapter](../../java/awt/event/MouseAdapter.html "class in java.awt.event")

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:

Parameters:

event - the event in question

mousePressed

public void mousePressed(MouseEvent event)

Parameters:

event - the event in question

mouseDragged

public void mouseDragged(MouseEvent event)

Called when the mouse is pressed and dragged. Does nothing.

Specified by:

Parameters:

event - the event in question

mouseMoved

public void mouseMoved(MouseEvent event)

Called when the mouse is moved. Determines whether the tool tip should be displayed.
