我如何检查鼠标点击 Python 3.8？

Question

How do I check for LMB in Python?

I want to check for when the left mouse button (left click) is clicked to make a drawing system through Kivy. I can't find it anywhere or figure out how to do it.

if draw_mode_free == True:
    if playerClicking == True:
        with self.canvas:
   # draw a line using the default color
   Line(points=(x1, y1, x2, y2, x3, y3))

   # lets draw a semi-transparent red square
   Color(0, 0, 0, 1, mode='rgba')
   Rectangle(pos=self.pos, size=self.size)

Answer 1

Use the standard Kivy on_touch_down , on_touch_move and on_touch_up methods to receive and make use of incoming touch events (which includes mouse clicks).

The touch objects you receive include data about what button is pressed, accessible via touch.profile['button'] (and possibly directly via touch.button , not sure).
