I’m trying to write a function where I can click on the screen, and a dot will be drawn in the location where I clicked - but nothing ever shows up. I click on the mouse, and nothing happens. I’ve tried making a predefined square and a predefined bunch of lines appear on the screen when I click the mouse, and nothing happens. The only thing that shows up is my test line in the console that I use to verify that my callback function is getting called when I click the mouse (which it is)
I’ve tried changing the colour, changing the point size to 8.0 - but no shapes, dots, or lines ever show up. Does anyone have any insight as to why this is happening? Thanks very much in advance.
