Hi Colin I'm afraid I can't answer your question from personal experience, but the Jurtle website lists the requirements as: Windows 98, ME, NT, 2000, XP Mac...
John, You guys are definitely treading in uncharted waters. Jurtle wasn't really designed with the idea of non-Turtle threads using the Turtle API calls. I...
Bill, Well, this isn't the behavior we're seeing. If we press the blue button 4 times, it takes 5 presses of the STOP button ( 1 for each spawned thread and 1...
The Stop button will only stop the Turtle thread. Any other threads that you may start are unknown to Jurtle and must terminate on their own (the normal case)...
Hi Bill, With the changes you suggested to create a separate drawing thread, my students found that if they changed the number of iterations in the ColorWheel...
... Yes, that's it exactly. If you don't need to see the intermediate drawing there is no need for a separate thread. Once you return from the slider's event...
Bill, I was afraid you were going to say that, but since you've provided me with a working example, I'm glad. I've talked about multi-threading to my students...
John, This is normal when executing code on the Event Thread. Because the event thread is used for both events and drawing updates, it is somewhat tricky to...
Howdy Bill, For the past few classes, I've been going over GUI interface programming with my students. I started them off with the slider example (PolySpiral),...
No, there is no way to show just the Display pane without the rest of the interface being visible. It seems you are really stretching Jurtle outside of its...
Is there any way to hide the java programme? basically I want open Display window directly when Jurtle editor was opened, this is for presenataion. so I want...
You cannot run any of the Turtle subclasses outside of Jurtle. Jurtle sets up the appropriate display area that Turtles require. In theory I could extract the...
Is there a way to run the BouncingBalls example from the command line? When I try to run the example and include the Jurtle.jar file in the classpath I get a...
... There is no way to do this. The Jurtle display area is controlled by the physical size of the window. There is no virtual display. Sorry. -- Bill...
Hi jhon I am taking about display area should go beyond the present display in the Jurtle even after minimize the left side file content list and bottom consol...
Chander, I'm not sure I understand your question. You can hide the panel on the left which lists the contents of your current folder by dragging the panel...
Hi All I need to increase the display seize in the Jurtle, I need to draw multiple flowers so that extends height of the editor so what is max limit for the...
Hi all at last fixed my self, to fill the different colors to petals in Flower.java, just I replaced petal method with this code. private void petal( double...
Chander, I gave you bad advice on using fillArc. This method doesn't do what I thought. It will draw a pie shaped wedge rather than a 1/2 a petal like I...
Jhon I used this fillArc method in arcRight() or arcLeft() , this works, but the problem is it over rides each petal at same positions of X, Y. I need it...
Chander, I haven't done much of any graphics programming outside of Jurtle's Turtle methods, but you can get the coordinates of the current Turtle's position...
I tried to do same way in arcRight() or arcLeft() but I couldnot able to find the X, Y positions and width & height, can you help me how to figure out the...
That's going to be a bit tricky to do. Turtle Graphics is designed mainly for line drawing, not for filing areas. You would probably be better off replacing...
Hi All I need to fill in each petal with different colors in Flower.java example. i can draw each petal with different colors, but I couldn't able to fill...
Hi Bill thanks for the responce, I got the Flower.java, but I couldn't able to convert that programme into java Applet or java application. and the flower...
Chander, This sounds like a school assignment. What have you tried so far? We can help, but can't do your assignment for you. Jurtle has a "Flower.java"...
Hi I need to draw a flower or something, which looks like beauty. with different radius and degrees in Applet, the no of petals varies, so each petal shouldnot...
