KeyEvent & Constant Field Values

in Programming Questions • 1 year ago

I don't understand if it's possible to create a KeyEvent this way:

import java.awt.event.KeyEvent;
int A_Z = 26;
ArrayList<KeyEvent> ALFABET = new ArrayList<KeyEvent>(A_Z);
ALFABET.add(0, (KeyEvent)(char(65)));

that gives this error: Cannot cast from char to KeyEvent

is it possible to get the keyCode to assign to ALFABET?

Thank you for any kind of help!

Well, the first reaction I have is: "Why?".
Why do you use KeyEvent instead of plain old Processing keyXXX() methods?
Why do you need to store these KeyEvents? How to you plan to use them?
Why do you use an array list if the number of elements is known in advance?
Why do you store values that can be computed on the fly?
Why do you mention keyCode which isn't a KeyEvent at all (but a part of it)?

Explaining the purpose of your code might help in giving advice, there might be better ways. The solution to your problem is simple to give, but your problem is probably not the best way to do what you want to do (too convoluted).

I want to create an a program that simulate a user with some behaviours on a computer. Among these I would like to make him write the name a folder, or write words in a notepad.

So I can't use the keyPressed(), because no one will press a key.

the keyCode was because of the late night and I thought it was possible to store these values launching the application and pressing all the letters so that:

ALFABET[next] = key; (you are right, why ArrayList knowing the length? thanks)

I that way, actually it is possible to store the value try this, when you launch it press the letters from B to Z (uppercase), then press SPACEBAR and find within 2000 ms a place to write like a sketch or a wordpad...

This code doesn't work with the TAB key and I guess many other keys such CTRL and ALT...

import java.awt.event.KeyEvent;
import java.awt.AWTException;
import java.awt.Robot;
Robot robot;
int[] ALFABET;
void setup() {
try {
robot = new Robot();
}
catch(AWTException a) {
println(a);
a.printStackTrace();
}
ALFABET = new int[27];
ALFABET[0]= KeyEvent.VK_A;
println(ALFABET[0]);
}
int next = 1;
void draw() {
for (int i=0; i< next; i++) {
println(ALFABET[i]);
}
}
void keyPressed() {
if (next<27) {
ALFABET[next] = key;
next++;
}
if (key == ' ') {
robot.delay(2000);
for (int i=0; i< next; i++) {
robot.keyPress(ALFABET[i]);
}
}
}
