Name

selectFolder()

Description

Opens a platform-specific file chooser dialog to select a folder. After the selection is made, the selection will be passed to the 'callback' function. If the dialog is closed or canceled, null will be sent to the function, so that the program is not waiting for additional input. The callback is necessary because of how threading works.

Examples

  • void setup() {
  selectFolder("Select a folder to process:", "folderSelected");
}

void folderSelected(File selection) {
  if (selection == null) {
    println("Window was closed or the user hit cancel.");
  } else {
    println("User selected " + selection.getAbsolutePath());
  }
}

Syntax

  • selectFolder(prompt, callback)
  • selectFolder(prompt, callback, file)
  • selectFolder(prompt, callback, file, callbackObject)

Parameters

  • prompt(String)message to the user
  • callback(String)name of the method to be called when the selection is made

Return

  • void
