I am creating a screen recorder software using Java. Almost 80% work has been completed. Now I need to create a visual marker of mouse clicks using Java. So that I can see in the playback video that where the mouse has been clicked. How can I do that?
Does anyone have any code example?
Very simple. Read the point where the mouse is clicked by the user with getX() and getY() methods of MouseListener. At the point, draw a oval with drawOval() methods of java.awt.Graphics class. Try the following code which I am sure solves your problem.
import java.awt.*;
import java.awt.event.*;
// no window closing code
public class MouseXY extends Frame implements MouseListener, MouseMotionListener
{
int x , y;
String str =" ";
public MouseXY()
{
setSize(500, 500);
setVisible(true);
addMouseListener(this); // register both the listeners with frame
addMouseMotionListener(this);
} // override the 5 abstract methods of ML
public void mouseEntered(MouseEvent e)
{
setBackground(Color.green);
x = e.getX();
y = e.getY();
str ="Mouse Entered";
repaint();
}
public void mouseExited(MouseEvent e)
{
setBackground(Color.red);
x = e.getX();
y = e.getY();
str ="Mouse Exited";
repaint();
}
public void mouseClicked(MouseEvent e)
{
setBackground(Color.gray);
x = e.getX();
y = e.getY();
str ="Mouse Clicked";
repaint();
}
public void mouseReleased(MouseEvent e)
{
setBackground(Color.blue);
x = e.getX();
y = e.getY();
str ="Mouse Released";
repaint();
}
public void mousePressed(MouseEvent e)
{
setBackground(Color.lightGray);
x = e.getX();
y = e.getY();
str ="Mouse pressed";
repaint();
} // override the 2 abstract methods of MML
public void mouseDragged(MouseEvent e)
{
setBackground(Color.magenta);
x = e.getX();
y = e.getY();
str ="Mouse Dragged";
repaint();
}
public void mouseMoved(MouseEvent e)
{
setBackground(Color.yellow);
x = e.getX();
y = e.getY();
str = "Mouse Moved";
repaint();
}
public void paint(Graphics g)
{
g.setColor(Color.blue);
g.fillOval(x , y , 10 , 10);
g.drawString(x +", "+ y , x , y);
g.drawString(str , x , y -10); // to draw the string above y coordinate
}
public static void main(String args[ ])
{
new MouseXY();
}
}
