How To Press Mouse Programmatically

In this post, we will discuss how to handle mouse press programmatically without having manual intervention. This is sometimes handy when we are in need to perform mouse click using the program.

Below mentioned is the code snippet showing the mouse press using Java's in-built awt class Robot.

// Create instance of Robot Class

Robot bot = new Robot();



// Move the bot position to given coordinates

bot.mouseMove( x, y );



// Press and Release the mouse to simulate click

bot.mousePress( InputEvent.BUTTON1_MASK );

bot.mouseRelease( InputEvent.BUTTON1_MASK );



System.out.println( "Mouse clicked at: " + x + " : " + y );

This is how we can simply perform mouse click using a program. The below-mentioned code shows a further enhancement to it by using a simple implementation of Thread to listen for the change and perform the click.

package com.myapp.utilities;



import java.awt.AWTException;

import java.awt.Robot;

import java.awt.event.InputEvent;



public class MouseClickUtility implements Runnable {



	public static boolean active	= false;

	public static int interval	= 500;



	@Override

	public void run() {



		try {



			while( true ) {



				if( active ) {



					int mouseY = MouseInfo.getPointerInfo().getLocation().y;

					int mouseX = MouseInfo.getPointerInfo().getLocation().x;

	

					System.out.println( "Mouse positioned at: " + mouseY + " : " + mouseX );



					Robot bot = new Robot();



					bot.mouseMove( mouseY, mouseX );



					bot.mousePress( InputEvent.BUTTON1_MASK );

					bot.mouseRelease( InputEvent.BUTTON1_MASK );



					System.out.println( "Mouse clicked at: " + x + " : " + y );

				}



				Thread.sleep( interval );

			}

		}

		catch( InterruptedException e ) {



			e.printStackTrace();

		}

		catch( AWTException e ) {



			e.printStackTrace();

		}

	}

}
