Anyone know if there is a way to restrict text input to a GTextField? I only want to allow numeric related chars (0123456789.-)? I have a function defined to handle textfield events and it's getting called but I'm not sure where to go from there.

tx!

Hi - I am running into an issue where calling 'selectInput' freezes up my project. I can call selectInput from a mouse event and it works but not from a function subsequent to calling 'selectInput. This is on OSX and have tested it in the IDE as well as in an exported application.

The functionality is for a simple text file converter: user selects a text file, do some processing and then prompt the user to save the file under a new name. I stripped out everything in the test sketch below to try to isolate the issue.

Anyone seen this before and is there a workaround?


thanks!

1. 
   void setup() {
     size(200, 200);
   }
   
   void draw() {
   }
   
   
   void test(String loadPath) {
   
     String output[] = new String[25];
   
     for(int i = 0; i < 25; i++) {
       output[i] = str(random(25));
     }
   
     println("open");
     String savePath = selectOutput("Save:");
     if (savePath != null) {
       println(savePath);
       saveStrings(savePath, output);
     }
     println("done");
   }
   
   void mousePressed() {
    
     String loadPath = selectInput();  // Opens file chooser
     if (loadPath == null) {
       println("No file was selected...");
     }
     else {
       test(loadPath);
     }
   }
    
   

Hi,

I am wondering if I can access the command line through Processing on OSX so that I can call various UNIX utilities that I have installed - passing params, etc. and then either having the utility write to a file or get back the result in Processing through stdout.

For example - I use a conversion utility called pstoedit and in the OSX Terminal would invoke it like this:

pstoedit -f plot-hpgl isCircleSqPlain.svg isCircleSqOut2.hpgl

The .svg file is converted to hpgl and the result is written to a .hpgl file.

Any tips on how to do this in Processing?

tx!
