Is it difficult to Draw a line on the canvas, then by clicking close to one end with the mouse, pick another point on the canvas and by clicking the mouse again to remove the old line and create the new one, while maintaining the lines other end ?

Also is it possible to have a tool tip when passing the mouse over a line ?

It's not very difficult to do, but there a number of ways of doing it.
To make it draw a line between 2 mouse clicks, write code that saves the coordinates of the first click, waits for the 2nd click and saves its coordinates, then draws a line from these 2 coordinates. There are a number of ways of determining whether the click is the 1st or 2nd, including storing it in a variable.

As for the tooltip, you can use API functions to display tooltips, but you would have to write code to determine if the mouse was currently over the line or not.

I am trying to draw a line, then by clicking near one end of the same line to choose it, an then to revise the location of the new end, I would like to draw a line for Example at 45 degrees, then pick and drag that end over and down to 30 degrees, removing the one that was drawn at 45.

Hey thanks Carm
