Getting values from Textfields doesn't work - the included example (ControlP5textfield) produces no output from the texts() function because hitting return/enter clears the field.  i'm not sure what other event would trigger the function.  the mousePressed() function works, but that doesn't help.

If you want to catch input when user hits enter or return, which others have asked about, supposedly you can do this:
http://processing.org/discourse/yabb_beta/YaBB.cgi?board=os_libraries_tools;action=display;num=1163646039;start=65#65

but it doesn't work, enter clears the textfield, and stringValue() returns "".  

also there is a lot of confusion between stringValue(), getText(), setValue().  seems like stringValue() and getText() are the same thing, and setValue() should be called setText()?  

the grey last character is a weird way to show the cursor.  the highlighted box already shows the focus.  when you set the value using enter, setValue(), or whatever, the grey character should change back to normal, but it doesn't.  

regardless, how do i get the value of a textfield when i hit return?

hi,
with 0.3.12 use the following methods to access text from a textfield. each textline that has been confirmed with RETURN, is stored in an array which can be accessed with getTextList(). why is the last character grey? its an indicator of the current cursor position, use left and right cursors to go back and forth, use up and down cursor to "scroll" through the history of textlines of a textfield.

this code snippet was taken from the controlP5textfield example that comes with the download.
Code:

  // using Textfield.getText();
  println("the current text of myTextfield: "+myTextfield.getText());
  // using Textfield.setText();
  myTextfield.setText("changed the text of a textfield");
  println("changing text of myTextfield to: "+myTextfield.getText());
  // using Textfield.getTextList();
  println("the textlist has "+myTextfield.getTextList().length+" items.");
  for(int i=0;i<myTextfield.getTextList().length;i++) {
    println("\t"+myTextfield.getTextList()[i]);
  }
 

when using the controlEvent method to access the string value of a textfield that has been fired with RETURN:

Code:

void controlEvent(ControlEvent theEvent) {
  println("controlEvent: controller '"+theEvent.controller().name()+"': "+theEvent.controller().stringValue());
}
 

the class Controller is abstract and is like a blueprint for all Controllers, which includes Textfield. each Controller in ControlP5 extend class Controller. all Controllers share the methods that are provided by class Controller, but each Controller can have its own set of methods, like in the case above. class Controller does not know that Textfield has a method setText, therefore you need to cast theEvent.controller() into a Textfield with ((Textfield)theEvent.controller()) then you can use:
Code:

((Textfield)theEvent.controller()).setText(s)
