I'm loving ithow about you? You started out simple by detecting the mouse cursor position and you built on that from there. You even learned how to make the mouse cursor disappear and to replace it with your ownthat's a very cool thing to know. You became more accustomed to more of the dynamics of line drawing and you even learned a command that clears the screen. You got so advanced in this chapter that you even set up a file that allows the user to draw on the screen and change his line color . On top of that, you learned all about dragging and dropping. You pretty much mastered the mouse. Congrats!
