Word Wrap by Divide and Conquer To layout and wrap text into lines, we will put the letters into three nested kinds of containers. Letters are on the inner level. Adjacent letters are grouped into Word objects. Groups of Words are in Problem objects. Each problem corresponds to a line of text. We call them Problems to emphasize that each one can be processed independently. The letters themselves remain in the contents of the text field box. Each letter is pointed to both by the text field box and by a Word. The container of a letter is always the text field.

Dividing Words and Problems We are going to put the letters into Word objects. Besides the letters in order, the word object knows its width (last letter right - first letter left). Step 1. Put the entire paragraph into one word. Words are shown with a green border.

The next level up is called a Problem. It is a collection of words in order. We start by putting the single very long word into a problem. Problems are shown with a red border. There is a list of problems, shown in yellow.

Step 5. Find the first word that is not white space, for which its last letter right is greater than Fw. Split the problem before that word. When there are several problems in the yellow list, they may be worked on incrementally in any order. Note that Step 3 can be lazy. The only words we care about are those that cross the right margin Fw. Words that are earlier in a line (problem) do not need to be divided. In Step 4, if a word is too long, make sure step 3 has been applied to every pair in it.

Subtract that from the x of every letter in the Problem. Step 3. For every pair of adjoining letters in a word, if one is white space and the other is not, split the word at the place between them. If at least one is not a letter (i.e. some other kind of box), spilt the word at the place between them. Step 4. For each word, if its width is greater than the field width Fw, the word is too long to fit on one line. Put each letter in that word into its own Word object. This allows a line break to occur just after the last letter that fits on the line.

Step 2. Find all letters that are a carriage returns. For each one see if it is at the end of a Word. If it is not, split both the word and the problem just after the carriage return. To split a word, put the letters after the split into a new word. Insert the new word after the current word in the problem. To split a Problem, make a new problem and put all words after the split into it. The new problem is a new line of text and it must start at the left edge of the field. Note the x value of the left of the first letter.

Subtract that from the x of every letter in the Problem. Step 3. For every pair of adjoining letters in a word, if one is white space and the other is not, split the word at the place between them.

In Step 4, if a word is too long, make sure step 3 has been applied to every pair in it.

Step 6. Make sure nothing more can be done on any problem in steps 2, 4, and 5. Step 7. For each Problem, compute the maximum height of the letters in it. Compute the maximum descent of its letters. Step 8. For each problem in order, set its pivot y to be (the previous problem's pivot y) + (the previous problem's max descent) + (this problem's max height). Set the pivot y of each letters to its problem's pivot y. Each letter now has the proper x and y in the text field. Throw away the entire list of problems, including their words. The letters are still held by the contents collection of the text field.
