MouseAdapter abstract class and implements the mouseClicked(MouseEvent evt) method. The MouseEvent getX() and getY() methods will return the coordinates relative to the source of the event. This method translates the current mouse coordinates into world coordinates. the mouse button is released (regardless of whether the mouse position is within the. Gets the Cursor that should be displayed when this mouse adapter is active. $ javac TestJLabel.java & java TestJLabel LinkController extends MouseAdapter implements MouseMotionListener. To find out the coordinates of the mouse cursor, call evt. Use translatePoint() to modify these coordinates by a specified amount.
So a developer can define methods for events specific to the application. void mouseDown(MouseEvent e) Sent when a mouse button is pressed. I suppose that if the mouse moved away from the mousePressed location and then back to the mousePressed location when mouseReleased is called, then you might have an argument that mouseClicked should not be called. If a MouseListener object, mListener, needs to hear mouse events associated with a component. Use getX() and getY() or getPoint() to obtain the coordinates of the mouse event. The MouseAdapter class (the AWT adapter class) is abstract. MouseAdapter() Method Summary All MethodsInstance MethodsConcrete Methods Modifier and Type Method Description void mouseDoubleClick(MouseEvent e) Sent when a mouse button is pressed twice within the (operating system specified) double click period. *EVERY* time the MouseListener reports no mouse position change in its MouseEvent instance between mousePressed and mouseClicked, it must invoke mouseClicked. 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 components bounds when the action happens. And that with no change in the reported mouse location nor any intervening mouseMoved call. Click the one called "click me".Īs you move around, pressing and releasing mouse button 1, you will see lines written to stderr.Įventually, if you reproduce the problem, you will see mousePressed followed only by mouseReleased. STEPS TO FOLLOW TO REPRODUCE THE PROBLEM : So, an inner MouseAdapter class is created here with just the mousePressed method overridden and.
In other words, if my mouse does not move (according to MouseEvent.getXOnScreen and MouseEvent.getYOnScreen) after mousePressed and mouseReleased, then mouseClicked should be called. Acting on mouse movement - display mouse coordinates. On a regular basis, I can use a simple app to cause a MouseListener to not call mouseClicked when it should.
