swing - How do I get an incremental display in java GUI program -


i have problem in moving java console gui program.

my console program loads words dictionary. uses each word in turn decrypt cipher, displaying deciphered text on screen first word, second word , on.

when write gui program, have command 

jtextarea.append(decipherment);

but nothing displayed until program has deciphered every word , decipherments displayed together, rather 1 one want.

the structure of gui program includes button code:

private void jbutton1actionperformed(java.awt.event.actionevent evt) {                                              decrypt(); }

and there section:

public void decrypt(){     ... }

that contains code load dictionary words, deciphering each word , display each decipherment method call: jtextarea.append(decipherment);

but, mentioned, individual decipherments not displayed. rather program runs end , displays decipherments together.

after reading other threads have feeling not writing gui program correctly haven’t found mistake is. appreciated.

your decrypting running in same thread gui , locking up. try spawning new thread run decryption, update gui in swing thread.

try this:

thread workthread = new thread(new runnable() {  // run process in new thread   public void run() {     decrypt();   } });  workthread.start();

how update swing thread:

eventqueue.invokelater(new runnable() {  // update swing thread here   public void run() {     jtextarea.append(decipherment);   } });

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
