Drawing lines by click two points
 

I have a GUI that displays a graph and I want to have some help with a code that allows you to click a point and then another point and then it draws a line. I need some help with this because I don't know were to start. ;)

In the MouseEvent's you can do this to get the location of the click:

Event.getX();

Event.getY();

That would help you with the coordinates of where the click happened, and where you should draw the line.

ok but how is that info stored?

Re: Drawing lines by click two points
 

you can store it in a double:

double x1 = Event.getX();

double y2 = Event.getY();

I don't know how you are going to tell if the first points were clicked unless you use a boolean...Like that boolean is set to true if the frst points are clicked, and then set to false..If that boolean is set to false, y would then store to the points in the second set of coordinates:

double x2 = Event.getX();
double y2 = Event.getY();
