Re: [pygame] Help - Events

[Henrique Nakashima <henrique.nakashima@xxxxxxxxx>]

When you get a mouse button down event, store the mouse location.

When you get a mouse button up event, check if the cursor location in
the mouse up event is the same as the location in the last mouse
button down event. If so, handle the removal. Else, handle the
dragging.

Hope this helps you.
