Hello, I finally make some input field to insert my data but I need my text inside input field shows the only capital letter. No matter I input the text with a capital letter or not.

Example: If I want to type text “hi” or “HI”  
I want to show like this.

-a- there is a event ENTERED  
that would be after the [enter]  
there you can call your own “text mod method”  
-b- there is a function  
[https://processing.org/reference/String\_toUpperCase\_.html](https://processing.org/reference/String_toUpperCase_.html)  
you can use for this.

import g4p_controls.*;

GTextArea txa1;

public void setup() {
  size(500, 300);
  G4P.setGlobalColorScheme(GCScheme.PURPLE_SCHEME);
  txa1 = new GTextArea(this, 10, 10, 480, 280);
  txa1.tag = "txa1";
  txa1.setPromptText("Text area 1");

}

public void draw() {
  background(200, 128, 200);
}

void workOnText() { // do something with the text
    println("get text area and check writing and save back ");
    String theText = txa1.getText();
    txa1.setText(theText.toUpperCase()); // change all to big
}

public void displayEvent(String name, GEvent event) {
  String extra = " event fired at " + millis() / 1000.0 + "s";
  print(name + " ");
  switch(event) {
  case CHANGED:
    println("CHANGED " + extra);
    break;
  case SELECTION_CHANGED:
    println("SELECTION_CHANGED " + extra);
    break;
  case LOST_FOCUS:
    println("LOST_FOCUS " + extra);
    break;
  case GETS_FOCUS:
    println("GETS_FOCUS " + extra);
    break;
  case ENTERED:
    println("ENTERED " + extra);  
    workOnText(); // add here
    break;
  default:
    println("UNKNOWN " + extra);
  }
}

public void handleTextEvents(GEditableTextControl textControl, GEvent event) { 
  displayEvent(textControl.tag, event);
}

What is wrong with the Shift or Caps Lock key?
