That being said, you should still post your code, because there may
be something that's causing the mouse events to be delayed for
whatever reason.
Here are the relevant lines of code...
def draw_point(event):
app.start_x = app.draw_area.canvasx(event.x)-app.brush_radius
app.start_y = app.draw_area.canvasy(event.y)-app.brush_radius
app.end_x = app.start_x+2*app.brush_radius
app.end_y = app.start_y+2*app.brush_radius
drawing.append(app.draw_area.create_oval(app.start_x,
app.start_y, app.end_x, app.end_y, fill=app.draw_color[1],
outline=app.draw_color[1], width=0))
print drawing
app.draw_area.bind("<B1-Motion>", draw_point)
So you'll have to interpolate a line between the two points and
draw a series of ovals.
How would I go about doing this? The final result I'd like would be
what Paint does, but I didn't know how to draw on the canvas while
the left mouse button was being held. The closest I could get to
this was binding the draw_point function to <B1-Motion>, and I don't
see how I could know when the mouse was being dragged quickly.
Thanks, Johnston Jiaa
