Exploring onMousePress and onMouseRelease Functions

The video tutorial explains the onMousePress and onMouseRelease functions, which capture mouse click and release events to create and modify circles on a canvas. The onMousePress function captures the x and y coordinates of a mouse click to draw a circle, while onMouseRelease changes the circle's color upon release. The tutorial also covers how mouse events differ from regular events, particularly in terms of inspecting elements using the control key.

What is the primary purpose of the 'on mouse press' function?

• To draw a circle on the screen

• To capture the mouse's x and y coordinates upon left click

• To change the color of the circle

• To release the mouse click

What parameters are commonly used in the 'on mouse press' function to represent coordinates?

• a and b

• height and width

• mouse x and mouse y

• radius and diameter

What syntax is used to define a function in Python?

• function()

• def

• define()

• func:

What happens when the 'on mouse press' function is executed?

• A square is drawn

• A message is displayed

• A circle with a radius of 10 is created at the click location

• The screen clears

What is the effect of clicking the mouse in the canvas area?

• A sound is played

• The canvas color changes

• A circle is drawn at the click location

• The page reloads

How does the 'on mouse release' event differ from 'on mouse press'?

• It creates a square instead of a circle

• It deletes the circle drawn by 'on mouse press'

• It changes the circle's color upon mouse release

• It captures right-click actions

What visual change occurs when the 'on mouse release' function is triggered?

• The circle becomes transparent

• The circle's color changes to green

• The circle moves to a new location

• The circle's radius increases

Why might coordinates not be visible when performing mouse events?

• Because of a programming error

• Due to the mouse being used for an event

• Because the coordinates are always hidden

• The screen is not refreshed

How can you view coordinates during a mouse event?

• By pressing the shift key

• By refreshing the page

• By holding the control key

• By double-clicking the mouse

What does holding the control key reveal during a mouse event?

• Error messages

• Circle properties like center coordinates, radius, and color

• A debug console

• A help menu
