Keeping points displayed as new ones created
Good Day,
I made a simple program that creates 2 points based on mouse click position and draws lines between them
Since it happens several times new points are created and new lines are drawn.... Works fine all points are saved in an array
My problem is after line drawn between two points, when user clicks a new point for a new line
the old line/old points disappear.
How do i keep the points displayed all the time

Store each set of the point in a list / array and redraw them again.
When you know how to do it then you may do it wrong.
When you don't know how to do it then it is not that you may do it wrong but you may not do it right.
