OpenJDK 27 · java.awt.event.MouseEvent · APIdia, the JavaDoc alternative

An event which indicates that a mouse action occurred in a component. A mouse action is considered to occur in a particular component if and only if the mouse cursor is over the unobscured part of the component's bounds when the action happens. For lightweight components, such as Swing's components, mouse events are only dispatched to the component if the mouse event type has been enabled on the component. A mouse event type is enabled by adding the appropriate mouse-based EventListener to the component (MouseListener or MouseMotionListener), or by invoking Component#enableEvents(long) with the appropriate mask parameter (AWTEvent.MOUSE_EVENT_MASK or AWTEvent.MOUSE_MOTION_EVENT_MASK). If the mouse event type has not been enabled on the component, the corresponding mouse events are dispatched to the first ancestor that has enabled the mouse event type.

For example, if a MouseListener has been added to a component, or enableEvents(AWTEvent.MOUSE_EVENT_MASK) has been invoked, then all the events defined by MouseListener are dispatched to the component. On the other hand, if a MouseMotionListener has not been added and enableEvents has not been invoked with AWTEvent.MOUSE_MOTION_EVENT_MASK, then mouse motion events are not dispatched to the component. Instead the mouse motion events are dispatched to the first ancestors that has enabled mouse motion events.

This low-level event is generated by a component object for:

Mouse Events
- a mouse button is pressed
- a mouse button is released
- a mouse button is clicked (pressed and released)
- the mouse cursor enters the unobscured part of component's geometry
- the mouse cursor exits the unobscured part of component's geometry
Mouse Motion Events
- the mouse is moved
- the mouse is dragged

A MouseEvent object is passed to every MouseListener or MouseAdapter object which is registered to receive the "interesting" mouse events using the component's addMouseListener method. (MouseAdapter objects implement the MouseListener interface.) Each such listener object gets a MouseEvent containing the mouse event.

A MouseEvent object is also passed to every MouseMotionListener or MouseMotionAdapter object which is registered to receive mouse motion events using the component's addMouseMotionListener method. (MouseMotionAdapter objects implement the MouseMotionListener interface.) Each such listener object gets a MouseEvent containing the mouse motion event.

When a mouse button is clicked, events are generated and sent to the registered MouseListeners. The state of modal keys can be retrieved using InputEvent#getModifiers and InputEvent#getModifiersEx. The button mask returned by InputEvent#getModifiers reflects only the button that changed state, not the current state of all buttons. (Note: Due to overlap in the values of ALT_MASK/BUTTON2_MASK and META_MASK/BUTTON3_MASK, this is not always true for mouse events involving modifier keys). To get the state of all buttons and modifier keys, use InputEvent#getModifiersEx. The button which has changed state is returned by MouseEvent#getButton

For example, if the first mouse button is pressed, events are sent in the following order:


    id              modifiers    buttonMOUSE_PRESSED:  BUTTON1_MASK BUTTON1
    MOUSE_RELEASED: BUTTON1_MASK BUTTON1
    MOUSE_CLICKED:  BUTTON1_MASK BUTTON1

When multiple mouse buttons are pressed, each press, release, and click results in a separate event.

For example, if the user presses button 1 followed by button 2, and then releases them in the same order, the following sequence of events is generated:


    id              modifiers    buttonMOUSE_PRESSED:  BUTTON1_MASK BUTTON1
    MOUSE_PRESSED:  BUTTON2_MASK BUTTON2
    MOUSE_RELEASED: BUTTON1_MASK BUTTON1
    MOUSE_CLICKED:  BUTTON1_MASK BUTTON1
    MOUSE_RELEASED: BUTTON2_MASK BUTTON2
    MOUSE_CLICKED:  BUTTON2_MASK BUTTON2

If button 2 is released first, the MOUSE_RELEASED/MOUSE_CLICKED pair for BUTTON2_MASK arrives first, followed by the pair for BUTTON1_MASK.

Some extra mouse buttons are added to extend the standard set of buttons represented by the following constants:BUTTON1, BUTTON2, and BUTTON3. Extra buttons have no assigned BUTTONx constants as well as their button masks have no assigned BUTTONx_DOWN_MASK constants. Nevertheless, ordinal numbers starting from 4 may be used as button numbers (button ids). Values obtained by the getMaskForButton(button) method may be used as button masks.

MOUSE_DRAGGED events are delivered to the Component in which the mouse button was pressed until the mouse button is released (regardless of whether the mouse position is within the bounds of the Component). Due to platform-dependent Drag&Drop implementations, MOUSE_DRAGGED events may not be delivered during a native Drag&Drop operation. In a multi-screen environment mouse drag events are delivered to the Component even if the mouse position is outside the bounds of the GraphicsConfiguration associated with that Component. However, the reported position for mouse drag events in this case may differ from the actual mouse position:

In a multi-screen environment without a virtual device:
The reported coordinates for mouse drag events are clipped to fit within the bounds of the GraphicsConfiguration associated with the Component.
In a multi-screen environment with a virtual device:
The reported coordinates for mouse drag events are clipped to fit within the bounds of the virtual device associated with the Component.

An unspecified behavior will be caused if the id parameter of any particular MouseEvent instance is not in the range from MOUSE_FIRST to MOUSE_LAST-1 (MOUSE_WHEEL is not acceptable).

MouseEvent back to summary

MouseEvent	back to summary
public MouseEvent(Component source, int id, long when, int modifiers, int x, int y, int xAbs, int yAbs, int clickCount, boolean popupTrigger, int button) Constructs a `MouseEvent` object with the specified source component, type, time, modifiers, coordinates, absolute coordinates, click count, popupTrigger flag, and button number. Creating an invalid event (such as by using more than one of the old _MASKs, or modifier/button values which don't match) results in unspecified behavior. Even if inconsistent values for relative and absolute coordinates are passed to the constructor, the mouse event instance is still created and no exception is thrown. This method throws an `IllegalArgumentException` if `source` is `null`. Parameters source:Component The `Component` that originated the event id:int An integer indicating the type of event. For information on allowable values, see the class description for `MouseEvent` when:long A long integer that gives the time the event occurred. Passing negative or zero value is not recommended modifiers:int a modifier mask describing the modifier keys and mouse buttons (for example, shift, ctrl, alt, and meta) that are down during the event. Only extended modifiers are allowed to be used as a value for this parameter (see the `InputEvent#getModifiersEx` class for the description of extended modifiers). Passing negative parameter is not recommended. Zero value means that no modifiers were passed x:int The horizontal x coordinate for the mouse location. It is allowed to pass negative values y:int The vertical y coordinate for the mouse location. It is allowed to pass negative values xAbs:int The absolute horizontal x coordinate for the mouse location It is allowed to pass negative values yAbs:int The absolute vertical y coordinate for the mouse location It is allowed to pass negative values clickCount:int The number of mouse clicks associated with event. Passing negative value is not recommended popupTrigger:boolean A boolean that equals `true` if this event is a trigger for a popup menu button:int An integer that indicates, which of the mouse buttons has changed its state. The following rules are applied to this parameter: If support for the extended mouse buttons is `disabled` by Java then it is allowed to create `MouseEvent` objects only with the standard buttons: `NOBUTTON`, `BUTTON1`, `BUTTON2`, and `BUTTON3`. If support for the extended mouse buttons is `enabled` by Java then it is allowed to create `MouseEvent` objects with the standard buttons. In case the support for extended mouse buttons is `enabled` by Java, then in addition to the standard buttons, `MouseEvent` objects can be created using buttons from the range starting from 4 to `MouseInfo.getNumberOfButtons()` if the mouse has more than three buttons. Annotations @SuppressWarnings:deprecation Exceptions IllegalArgumentException: if `button` is less than zero if `source` is null if `button` is greater than BUTTON3 and the support for extended mouse buttons is `disabled` by Java if `button` is greater than the `current number of buttons` and the support for extended mouse buttons is `enabled` by Java if an invalid `button` value is passed in if `source` is null Since 1.6 See Also `getSource()`, `getID()`, `getWhen()`, `getModifiers()`, `getX()`, `getY()`, `getXOnScreen()`, `getYOnScreen()`, `getClickCount()`, `isPopupTrigger()`, `getButton()`, `Toolkit#areExtraMouseButtonsEnabled()`, `java.awt.MouseInfo#getNumberOfButtons()`, `InputEvent#getMaskForButton(int)`

public MouseEvent(Component source, int id, long when, int modifiers, int x, int y, int xAbs, int yAbs, int clickCount, boolean popupTrigger, int button)

Constructs a MouseEvent object with the specified source component, type, time, modifiers, coordinates, absolute coordinates, click count, popupTrigger flag, and button number.

Creating an invalid event (such as by using more than one of the old _MASKs, or modifier/button values which don't match) results in unspecified behavior. Even if inconsistent values for relative and absolute coordinates are passed to the constructor, the mouse event instance is still created and no exception is thrown. This method throws an IllegalArgumentException if source is null.

Method Detail

getButton back to summary

getButton	back to summary
public int getButton() Returns which, if any, of the mouse buttons has changed state. The returned value is ranged from 0 to the `MouseInfo.getNumberOfButtons()` value. The returned value includes at least the following constants: `NOBUTTON` `BUTTON1` `BUTTON2` `BUTTON3` It is allowed to use those constants to compare with the returned button number in the application. For example, if (anEvent.getButton() == MouseEvent.BUTTON1) { In particular, for a mouse with one, two, or three buttons this method may return the following values: 0 (`NOBUTTON`) 1 (`BUTTON1`) 2 (`BUTTON2`) 3 (`BUTTON3`) Button numbers greater than `BUTTON3` have no constant identifier. So if a mouse with five buttons is installed, this method may return the following values: 0 (`NOBUTTON`) 1 (`BUTTON1`) 2 (`BUTTON2`) 3 (`BUTTON3`) 4 5 Note If support for extended mouse buttons is `disabled` by Java then the AWT event subsystem does not produce mouse events for the extended mouse buttons. So it is not expected that this method returns anything except `NOBUTTON`, `BUTTON1`, `BUTTON2`, `BUTTON3`. Returns:int one of the values from 0 to `MouseInfo.getNumberOfButtons()` if support for the extended mouse buttons is `enabled` by Java. That range includes `NOBUTTON`, `BUTTON1`, `BUTTON2`, `BUTTON3`; `NOBUTTON`, `BUTTON1`, `BUTTON2` or `BUTTON3` if support for the extended mouse buttons is `disabled` by Java Since 1.4 See Also `Toolkit#areExtraMouseButtonsEnabled()`, `java.awt.MouseInfo#getNumberOfButtons()`, `MouseEvent(Component, int, long, int, int, int, int, int, int, boolean, int)`, `InputEvent#getMaskForButton(int)`

public int getButton()

Returns which, if any, of the mouse buttons has changed state. The returned value is ranged from 0 to the MouseInfo.getNumberOfButtons() value. The returned value includes at least the following constants:

NOBUTTON
BUTTON1
BUTTON2
BUTTON3

It is allowed to use those constants to compare with the returned button number in the application. For example,

if (anEvent.getButton() == MouseEvent.BUTTON1) {

In particular, for a mouse with one, two, or three buttons this method may return the following values:

0 (NOBUTTON)
1 (BUTTON1)
2 (BUTTON2)
3 (BUTTON3)

Button numbers greater than BUTTON3 have no constant identifier. So if a mouse with five buttons is installed, this method may return the following values:

0 (NOBUTTON)
1 (BUTTON1)
2 (BUTTON2)
3 (BUTTON3)
4

getLocationOnScreen	back to summary
public Point getLocationOnScreen() Returns the absolute x, y position of the event. In a virtual device multi-screen environment in which the desktop area could span multiple physical screen devices, these coordinates are relative to the virtual coordinate system. Otherwise, these coordinates are relative to the coordinate system associated with the Component's GraphicsConfiguration. Returns:Point a `Point` object containing the absolute x and y coordinates.

getModifiersEx back to summary

getModifiersEx	back to summary
public int getModifiersEx() Overrides java.awt.event.InputEvent.getModifiersEx. Doc from java.awt.event.InputEvent.getModifiersEx. Returns the extended modifier mask for this event. Extended modifiers are the modifiers that ends with the _DOWN_MASK suffix, such as ALT_DOWN_MASK, BUTTON1_DOWN_MASK, and others. Extended modifiers represent the state of all modal keys, such as ALT, CTRL, META, and the mouse buttons just after the event occurred. For example, if the user presses button 1 followed by button 2, and then releases them in the same order, the following sequence of events is generated: `MOUSE_PRESSED`: `BUTTON1_DOWN_MASK` `MOUSE_PRESSED`: `BUTTON1_DOWN_MASK \| BUTTON2_DOWN_MASK` `MOUSE_RELEASED`: `BUTTON2_DOWN_MASK` `MOUSE_CLICKED`: `BUTTON2_DOWN_MASK` `MOUSE_RELEASED`: `MOUSE_CLICKED`: It is not recommended to compare the return value of this method using `==` because new modifiers can be added in the future. For example, the appropriate way to check that SHIFT and BUTTON1 are down, but CTRL is up is demonstrated by the following code: int onmask = SHIFT_DOWN_MASK \| BUTTON1_DOWN_MASK; int offmask = CTRL_DOWN_MASK; if ((event.getModifiersEx() & (onmask \| offmask)) == onmask) { ... } The above code will work even if new modifiers are added.

public int getModifiersEx()

Overrides java.awt.event.InputEvent.getModifiersEx.

Doc from java.awt.event.InputEvent.getModifiersEx.

Returns the extended modifier mask for this event.

Extended modifiers are the modifiers that ends with the _DOWN_MASK suffix, such as ALT_DOWN_MASK, BUTTON1_DOWN_MASK, and others.

Extended modifiers represent the state of all modal keys, such as ALT, CTRL, META, and the mouse buttons just after the event occurred.

For example, if the user presses button 1 followed by button 2, and then releases them in the same order, the following sequence of events is generated:

   MOUSE_PRESSED:  BUTTON1_DOWN_MASK
   MOUSE_PRESSED:  BUTTON1_DOWN_MASK | BUTTON2_DOWN_MASK
   MOUSE_RELEASED: BUTTON2_DOWN_MASK
   MOUSE_CLICKED:  BUTTON2_DOWN_MASK
   MOUSE_RELEASED:
   MOUSE_CLICKED:

It is not recommended to compare the return value of this method using == because new modifiers can be added in the future. For example, the appropriate way to check that SHIFT and BUTTON1 are down, but CTRL is up is demonstrated by the following code:

   int onmask = SHIFT_DOWN_MASK | BUTTON1_DOWN_MASK;
   int offmask = CTRL_DOWN_MASK;
   if ((event.getModifiersEx() & (onmask | offmask)) == onmask) {
       ...
   }

The above code will work even if new modifiers are added.

getMouseModifiersText back to summary

getMouseModifiersText	back to summary
public static String getMouseModifiersText(int modifiers) Returns a `String` instance describing the modifier keys and mouse buttons that were down during the event, such as "Shift", or "Ctrl+Shift". These strings can be localized by changing the `awt.properties` file. Note that the `InputEvent.ALT_MASK` and `InputEvent.BUTTON2_MASK` have equal values, so the "Alt" string is returned for both modifiers. Likewise, the `InputEvent.META_MASK` and `InputEvent.BUTTON3_MASK` have equal values, so the "Meta" string is returned for both modifiers. Note that passing negative parameter is incorrect, and will cause the returning an unspecified string. Zero parameter means that no modifiers were passed and will cause the returning an empty string. Parameters modifiers:int A modifier mask describing the modifier keys and mouse buttons that were down during the event Returns:String string string text description of the combination of modifier keys and mouse buttons that were down during the event Annotations @SuppressWarnings:deprecation Since 1.4 See Also `InputEvent#getModifiersExText(int)`
