----------------------------------- Neja Wed Jan 07, 2004 10:11 pm Paint Program:Staying on the canvas. ----------------------------------- How to I get the drawing part to stay on the canvas? (This is for drawing lines) I've fixed it so that if you click somewhere outside the canvas, it won't work, but if you click for the first point of the line to be on the canvas and then click somewhere outside the canvas, it will draw the line (like it's not supposed to). THis is for a paint program I'm supposed to make and I really suck at programming. Instead of posting the whole program, I'll just post the essential part of it; var canvas : int := GUI.CreateCanvas (112, 65, 640, 400) Draw.Line (113, 66, 113, 400, 7) Draw.Line (113, 66, 640, 66, 7) Draw.Fill (113, 65, 1, 7) var x, y, btnNumber, btnUpDown, buttons : int var newx, newy : int loop Mouse.ButtonWait ("down", x, y, btnNumber, btnUpDown) newx := x newy := y if newx > 112 and newx < maxx and newy > 75 and newy < maxy and x > 112 and y > 75 then loop Draw.Line (x, y, newx, newy, 0) % Erase previous line exit when Mouse.ButtonMoved ("up") Mouse.Where (newx, newy, buttons) Draw.Line (x, y, newx, newy, 1) % Draw line to position end loop % I think this is where I should put Mouse.Where, put I'm new with most of these commands and I'm not sure how I would use it. Mouse.ButtonWait ("up", newx, newy, btnNumber, btnUpDown) Draw.Line (x, y, newx, newy, 2) % Draw line to final position else end if end loop And if you all look you'll see that most of this code is in the Turing Refrence. No, I'm not stealing, I'm trying to learn this code and how to keep the lines within a set perimeter so I can apply it to my program. ----------------------------------- Neja Wed Jan 07, 2004 10:15 pm ----------------------------------- Oh! I apologize. I didn't realize chibitenshi_03 has a similar problem. Never mind this then.
