Re: VPL: How to run a graphical tkinter (Python) program

Hi Juan Carlos,

Thank you very much! I have added this script and I am now able to take user input and pass the input to turtle functions. I had a few more questions related to this -
1) In case of an error, I don't see an error message on the console anymore. Is there a way to enable this?
2) The UI closes immediately after the code is executed. I have currently added sleep() at the end of the code in order to see the output on the UI. Is there a way to make the UI stay a little longer so that the output could be observed without adding sleep().
3) Is there a way to set the screen size and location for the console as well as the UI?

I also had a question on the image formats that are supported -
4) I am trying to add a shape to the turtle using turtle.shape(imagename) and I am able to add .gif images but not other formats. Is there a restriction on the image format that could be used in VPL?

I also had a question on Input for Java programs -
5) I am doing a similar exercise in Java where I am taking user input and using it on the UI. For this I am currently using javax.swing.JOptionPane to take user inputs. Is there a similar script that I can use to take user inputs via console and use it for output on the UI?

Thank you again for your help!

Best Regards
Smita Shrivastava

I will try to answer your questions:
A1) You can add a "read" command to wait for the "return key"
echo "read"" >>vpl_execution
add after  "echo python3 ...
A2) I think that this issue about programming and not related to VPL or the custom script.
A3) Sorry, but I don't know.
A4) No. VPL manages as binary the image files with the following file extensions: gif, jpg, jpeg, png, ico. The use of these files programmatically is not related to VPL.
A5) No, I don't have a similar solution for Java. Notice that I have a specific script to resolve your problem with Python because a colleague had the same problem, and I wrote the script for him. We are planning to develop a global solution but not yet done.

best regards,
Juan Carlos.
