basic controlP5 textField question

in Contributed Library Questions • 1 years ago

Well, I've searched but i can't understand de difference between this two textFields in controlP5 examples. Why one is declared as MytextField and the other is called using a String name as a parameter? What's the difference?

code from the example

String textValue = "";
Textfield myTextfield;
void setup() {
size(400,400);
frameRate(25);
controlP5 = new ControlP5(this);
myTextfield = controlP5.addTextfield("texting",100,160,200,20);
myTextfield.setFocus(true);
controlP5.addTextfield("textValue",100,200,200,20);
}

Actually, I don't see that String textValue = ""; is used. They both use a string value as part of the first field, which is the controller name for the textfield. Using the first example myTextfield gives you a more flexibility to set all the textfield sub-components.

v.k.

jeff_g thanks. The textValue is used later in code, sorry this is the full code: (any way u have cleard things for me already), now he code from the example:

/**
* ControlP5 Textflied.
*
* for a more advanced example see textfieldAdvanced which
* demonstrates how to use keepFocus, setText, getText, getTextList,
* clear, setAutoClear, isAutoClear or submit.

import controlP5.*;
ControlP5 controlP5;
String textValue = "";
Textfield myTextfield;

controlP5 = new ControlP5(this);
myTextfield = controlP5.addTextfield("texting",100,160,200,20);
myTextfield.setFocus(true);
controlP5.addTextfield("textValue",100,200,200,20);
}
void draw() {
background(0);
}
void controlEvent(ControlEvent theEvent) {
println("controlEvent: accessing a string from controller '"+theEvent.controller().name()+"': "+theEvent.controller().stringValue());
}
public void texting(String theText) {
// receiving text from controller texting
println("a textfield event for controller 'texting': "+theText);
}
