6 years ago The box selection function can be edited in the canvas.py file. The core idea is how to confirm the list of boxes you want to delete. You can try to append the selected boxes into one list one by one and delete them at once.
Say i want to delete multiple boxes at once, without clicking each box and deleting separately. What changes would i make to the source code to either a) select multiple boxes with the mouse (overlapping them with a mouse box) or b) select multiple boxes by clicking each, and then pressing delete once.
