Methods

o selectLine 
 synchronized boolean selectLine(int line)
Selects the given line of text in the text box. requestFocus() should be called after this function to ensure that the highlight is displayed.

o makeSpaces 
 String makeSpaces(int n)
Returns:
A string with n spaces.
o format 
 public String format()
Uses RoBOTLTokenManager to tokenize the code in the text box, from which it recreates the string using proper indentation and spacing. The new string replaces the old one in the box and is returned. Warning: this is not yet complete. "Else" and "do-while" are not always handled correctly as of the current version. It should work for most situations, however.

Returns:
The new (formatted) string.
