Dear all  
I have to use the selectInput function on my sketch.  
Unfortunately I can’t find a detailed description of it. I don’t understand, for example, how to direct the selectInput in a directory or how to use file filter as “\*.txt”

Thank you very much for your help and cooperation  
regards

In addition to searching this forum and the old forum, there is the reference page – and keep in mind that you can also click through and find it in the JavaDoc:

- [https://processing.org/reference/selectInput\_.html](https://processing.org/reference/selectInput_.html)
- [http://processing.github.io/processing-javadocs/core/processing/core/PApplet.html#selectInput-java.lang.String-java.lang.String-](http://processing.github.io/processing-javadocs/core/processing/core/PApplet.html#selectInput-java.lang.String-java.lang.String-)

…or even search the source code:
