CS 115 Lab 4, Part C: Characterize the user's mouse clicks

The Big Picture

In this part of the lab, you will modify the program that you wrote for part B so that you can accept the user's mouse-clicks and determine in which row and column each click occurred. If a mouse-click happens to be outside of the grid, your program will report that as well.

Determining the row and the column of a mouse-click

Create a new Python program and call it lab04c.py. Copy and paste your previous program (lab04b.py) into it. Now, add the following loop to the end of your program and just before the last two lines.

    for i in range(10):
        c_point = window.getMouse()
        x_c_point = c_point.getX()
        y_c_point = c_point.getY()
        print('x =', x_c_point, 'y =', y_c_point)

The idea is to, just as in part A of this lab, accept the user's mouse-clicks and determine where they occur. In this part, if the mouse-click occurs in one of the num_rows * num_columns squares, we want to identify its row- and column-number (where the number of the first row and column is 1).

Remember that the top left of the grid begins at (100, 100).

Let's suppose that when you run your program and click the mouse, the x and the y of a mouse-click takes place at (235, 540). That is, x = 235 and y = 540. Here's a procedure you might follow:

To get the row: subtract top_left_y from 540 (the y-coordinate of the user's click) to get 440. So the click must have been 440 pixels below the top of the first row.
Divide 440 by the height of the square to get 7 (using integer division). This means the row number must be 8, since for a click to take place in row 8, its y has to be larger than or equal to 7 * 60 = 420 and less than 8 * 60 = 480.
To get the column number, subtract top_left_x from 235 to get 135. Given that top_left_x was 100, 235 - 100 = 135 is the x of the mouse-click measured from the left edge of the first column.
Since 135 // 60 = 2, the column number where the click occurred must have been 3.
Therefore, the mouse was clicked in row 8, column 3.

Answer Question 19 in your writeup.

Modify your program so that it accepts 10 user clicks and identify the row and the column in which the click occurred. If the click occurs outside of the grid, your program should indicate so. The output of your program should look like this for a 10x10 grid:

The click at (364, 195) is in row 2, column 5.
The click at (388, 48) is outside of the grid.
The click at (186, 481) is in row 7, column 2.
The click at (60, 472) is outside of the grid.
The click at (431, 366) is in row 5, column 6.
The click at (617, 248) is in row 3, column 9.
The click at (520, 765) is outside of the grid.
The click at (670, 484) is in row 7, column 10.
The click at (253, 430) is in row 6, column 3.
The click at (132, 444) is in row 6, column 1.

Be sure your docstring is up to date with your name and a current description of your program.
