Field Detail

output

public javax.swing.JTextArea output

The text area where the output is printed. This parameter is public in case there are parts of the program remaining that still print directly by adding to this output. Also, to print in that way would give more flexibility that the out() method offers.

outFrame

public javax.swing.JFrame outFrame

The frame for this window. This is public becaise Run_KRUT uses the setVisible() method of this class.

inited

public boolean inited

true if the output window is initiated, false if not. This parameter is changed at the end of the init method.
