Invoked when the mouse button has been clicked (pressed and released) on a component. In a class called Board, a constructor creates a multi-dimensional array of Mine objects. Methods inherited from class mouseClicked, mouseEntered, mouseExited. Private static void createAndShowGUI () įrame.getContentPane().setLayout(new BorderLayout()) įrame.getContentPane().add(new JLabel("don't click me"), BorderLayout.NORTH) įrame.getContentPane().add(lab, BorderLayout.EAST) įrame.getContentPane().add(new JLabel("don't click me either"), BorderLayout.I'm making a simple game in minesweeper, and I have a Mine class with a JButton and some other information, namely an x and y variable for its location. Invoked when a mouse button has been released on a component. If you can post the code that creates the JButtons for the mines, that might help. The fact that all actions seem to only be affecting that last button really does sound like you may be re-assigning the same button reference to multiple mines. This information is available from the MouseEvent. You should not have to send the x and y coordinates separately in the constructor. $ javac TestJLabel.java & java TestJLabel Often, when a mouse event occurs, you want to know the location of the mouse cursor. 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. *EVERY* time the MouseListener reports no mouse position change in its MouseEvent instance between mousePressed and mouseClicked, it must invoke mouseClicked. the mouse button is released (regardless of whether the mouse position is.

I can get the coordinates every time the mouse is pressed inside a JPanel for example, but not everywhere on screen. STEPS TO FOLLOW TO REPRODUCE THE PROBLEM : Thats the problem, i have extends MouseAdapter which inherits MouseMotionListener (if i remember correctly), but how do i tell it to set coordinates every time the mouse moves. 'Ctrl' + click will copy the current contents of the box/strip at the top of the map to the clipboard, though currently only copying of 'lon', 'lat' and 'zoom' are supported, not 'epsg' and 'proj4' as these do not change with pan and zoom. Issue a set of commands to display the mouse coordinates in your Microsoft Windows computer. ![]() 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.
