Is it RightClick ?

[Manikandan Adaikkalavan]

Hi,
how to detect whether itz Mouse's RightClick or LeftClick with the help of mouse event ??
I need to find out the right click ?

Thanks in advance,
Manikandan

[Manikandan Adaikkalavan]

i got it.
Answer is
if ((e.getModifiers() & InputEvent.BUTTON3_MASK) != 0)
System.out.println("RIGHT CLICK");
else System.out.println("LEFT CLICK");

This should work:

public void mouseClicked(MouseEvent e)
{
  try 
  {
    if (e.getModifiers() == MouseEvent.BUTTON3_MASK) 
    {
        doEdit();
    }
  } catch(Throwable ex) {
      System.err.println("ValidDialog.mouseClicked: " + ex);
  }
}

Perhaps the documentation on MouseEvent will give you an idea...

Ah yes, the old three-fer response... and you answered your own question in one of the responses - not bad, not bad.
Here's an example another strategy you could use:

import java.applet.Applet;
import java.awt.Graphics;
import java.awt.event.MouseListener;
import java.awt.event.MouseEvent;
 
public class StudyWhichMouseButtonClicked extends Applet implements MouseListener 
{
    String buttonClicked = "" ;
    
    public void init() 
    {
        addMouseListener( this );
    }
    
    public void paint( Graphics g ) 
    {
        g.drawString( buttonClicked , 100 , 100 );
    }
    
    public void mouseClicked( MouseEvent mouseEvent )
    {
        switch ( mouseEvent.getButton() ) 
        {
            case MouseEvent.BUTTON1 : buttonClicked = "left"   ; break ;
            case MouseEvent.BUTTON2 : buttonClicked = "middle" ; break ;
            case MouseEvent.BUTTON3 : buttonClicked = "right"  ; break ;
        }
        
        repaint() ;
    }
    
    public void mousePressed( MouseEvent mouseEvent ) {}
    
    public void mouseReleased( MouseEvent mouseEvent ) {}
    
    public void mouseEntered( MouseEvent mouseEvent ) {}
    
    public void mouseExited( MouseEvent mouseEvent ) {}
    
}

Note that your example code would consider a click from the middle mouse button (if it exists) as a click from the left mouse button.

[Manikandan Adaikkalavan]

whether the following condition fails
if ((e.getModifiers() & InputEvent.BUTTON3_MASK) != 0)
{}
......
if there is a middle button in MOUSE ?

[Manikandan Adaikkalavan]

I tried this example...but giving compilation error

[Roy Ben Ami]

another solution i used to do myself was to use the methods: isMetaDown() and isControlDown()
if one of them returns true (the first i think) the the right button is pressed if the second returns true the middle button is pressed.
(could be the other way around , just check it).
this , in my opinion is a pretty good solution even before jdk 1.4 (before the getButton() method) because it works on macintoshes who only have 1 button mouse. so pressing control while pressing the one button emulates right button like it should.

Hi,
Sorry .....I totally got confused...
i need to have a check for rightclick whether the mouse has one button or two buttons or three buttons ...
whether the following code works fine for all cases ???
if ((e.getModifiers() & InputEvent.BUTTON3_MASK) != 0)
{
// Itz Right Click
}

I have two buttons in my Mouse and this works great....for other two ....i don't know....
Will somebody please help me out ???

Thanks,
Manikandan

[Manikandan Adaikkalavan]

Hi,
i got another solution....
There are three methods in
javax.swing.SwingUtilities class
public static boolean isLeftMouseButton(MouseEvent anEvent)
public static boolean isRightMouseButton(MouseEvent anEvent)
public static boolean isMiddleMouseButton(MouseEvent anEvent)
which can be used to find out which button is clicked!
