Dear all,
I am very new to processing and I would like to do the following things:

1. color the squares of my simple treemap

2.  it would be interesting to use a circular treemap instead the current one (which I guess is a PivotBySplitSize)

thanx for your help

here is my code:

import treemap.*;
Treemap map;
class WordItem extends SimpleMapItem {
String word;
WordItem(String word) {
this.word = word;
}
void draw( ) {
fill(346);
rect(x, y, w, h);
fill(0);
if (w > textWidth(word) + 6) {
if (h > textAscent( ) + 6) {
textAlign(CENTER, CENTER);
text(word, x + w/2, y + h/2);
}
}
}
}
class WordMap extends SimpleMapModel {
HashMap words;
WordMap( ) {
words = new HashMap( );
}
void addWord(String word) {
WordItem item = (WordItem) words.get(word);
if (item == null) {
item = new WordItem(word);
words.put(word, item);
}
item.incrementSize( );
}
void finishAdd( ) {
items = new WordItem[words.size( )];
words.values( ).toArray(items);
}
}
void setup( ) {
size(3500, 1500);
smooth( );

strokeWeight(0.99f);
PFont font = createFont("orator", 3);
textFont(font);
WordMap mapData = new WordMap( );
String[] lines = loadStrings("idiot.txt");
for (int i = 0; i < lines.length; i++) {
mapData.addWord(lines[i]);
}
mapData.finishAdd( );
map = new Treemap(mapData, 0, 0, width, height);
// Run draw( ) only once.
noLoop( );
}

void draw( ) {
background(#ffffff);
map.draw( );
save("idiot.tiff");
}


 

hello!

@ arenzky:

PhiLho is right.
Your code is much better readable with indents.
Processing does this automatically.
Use Menu Tools|AutoFormat.

What is
import treemap.*;
?

You have to show this library to us.
Is it from you?

Thanks!

Greetings,

don't think this is possible because all the work is being done by the treemap library which you don't have control over.

map = new Treemap(mapData, 0, 0, width, height);
...
map.draw( );

if map.draw() doesn't do colours then you're stuck. (unless you change the treemap code).

(actually, the change looks quite easy given that Treemap.draw() is
 public void draw() {
   Mappable[] items = model.getItems();
   for (int i = 0; i < items.length; i++) {
     items[i].draw();
   }
 }
you just need to change fill() and/or stroke() in the loop before the items[i].draw()
