Text editor base?

Processing Coding Questions

Hi, I made a small new version of you editor with less of computer ressources.
I create a “selectLine” variable to not use a for loop in keyPressed function.
Now ENTER and BACKSPACE touch works.

PFont font;

PImage save;
PImage open;
PImage brush;

color theme1 = color(0, 8, 48);
color theme2 = color(0, 7, 30);

boolean bluet = true;
boolean darkt = false;

int scrolli = 0;
int selectLine = 0;
float scrolli2;

Line l1 = new Line(40, 1);
Toolbar t = new Toolbar();
Scrollbar sb = new Scrollbar(585, 50, 350, 60);
RMBMenu r = new RMBMenu();

ArrayList<Line> lines;

void setup() {
    size(600, 400);
    surface.setTitle("EpicTextEditor v0.1");
    font = loadFont("TeXGyreAdventor-Bold-48.vlw");
    textFont(font);
    //save = loadImage("saveIcon.png");
    //open = loadImage("openIcon.png");
    //brush = loadImage("brushIcon2.png");
    lines = new ArrayList<Line>();
    for (int i = 0; i < 50; i++) {
        lines.add(new Line(i * 20 + 30, i));
    }
}

void draw() {
    background(theme1);
    //themes
    if (darkt) {
        theme1 = color(70);
        theme2 = color(30);
    }
    for (int i = 0; i < 50; i++) {
        Line l = lines.get(i);
        l.y = sb.setScrollObjectY(0, 650) + (i * 20 + 30);
    }
    for (int i = 0; i < 50; i++) {
        Line l = lines.get(i);
        l.display();
    }
    t.display();
    sb.display();
    r.display();
}

void mousePressed() {
    sb.mousePress();
    r.mousePress();

    for (int i = 0; i < 50; i++) {
        Line l = lines.get(i);
        l.mousePress();
    }
}

void mouseReleased() {
    sb.mouseRelease();
}

void keyPressed() {
    lines.get(selectLine).keyPress();
}

void mouseDragged() {
    for (int i = 0; i < 50; i++) {
        Line l = lines.get(i);
        l.mouseDrag();
    }
}

void mouseWheel(MouseEvent event) {
    scrolli = constrain(scrolli + event.getCount(), 0, 50);
    scrolli2 = map(scrolli, 0, 30, 70, 220);
    sb.sy = int(scrolli2);
}
