java - how to transmit user variables to paint method -

-

i'm new there might many problems in code below.
should take user written text text field , draw morse code it. gets text, transmits string in chararray form class, paint method doesn't draw anything(variables not recognized in paint method!!).

input: constructor gets link(or in that)of other class, char string, , place number in string output: last 3 rows drawn, other variables outside paint method not recognized!

here class doesn't work:

public class procesare extends canvas{     morse fereastra;     string lit="",cod="";     char car;     int nr;      public procesare(morse parinte,char c,int i){         fereastra=parinte;         car=c;  // or without "this" doesn't seem transmit values class         nr=i;         //this.lit=string.valueof(c);         switch (c){                 //this part testing values transmited, works                 case 'a':                     fereastra.canv.setbackground(color.orange);                     system.out.println(c+" .-");                      break;                 case 'b':                      fereastra.canv.setbackground(color.blue);                     system.out.println(c+" -...");                      break;                 case 'c':                      fereastra.canv.setbackground(color.red);                     system.out.println(c+" -.-.");                      break;                 case 'd':                      fereastra.canv.setbackground(color.green);                      system.out.println(c+" -..");                      break;                 default: break;             }     }      public void paint(graphics g){         lit=string.valueof(car);         switch (lit){                 case "a": cod=".-"; break;                 case "b": cod="-..."; break;                  default: break;             }         g.drawstring(lit,5,10+nr*10);         g.drawstring(cod,15,10+nr*10);         g.drawstring(lit,5,10);  // these aren't drawing !?!?          g.filloval(15, 3, 6, 6); // testing         g.drawstring("z",5,20);         g.filloval(15, 13, 6, 6);      } }

the main class, works:

public class morse extends frame {     xtext camp;     procesare proc,canv;     string s1, str;     char[] cuv;     int n;      public morse(string titlu){       super(titlu);       init();     }       public static void main (string args[]){         morse app=new morse("morse much?");         app.setsize(250,250);         app.show();     }     public boolean handleevent(event evt)  {       if (evt.id==event.window_destroy)       {system.exit(0);}       return super.handleevent(evt);     }      public void init(){         setlayout(new gridlayout(3,1,10,20));         setbackground(color.gray);         canv=new procesare(this,' ',0);         canv.setbackground(color.orange);         camp=new xtext(this,"introduceti textul aici:");                       add(camp);         add(canv);      }     public insets getinsets(){         return new insets(30,30,30,30);     }     void update(xtext input){          s1=input.ctext1.gettext();         cuv = s1.tochararray();          for(n=0;n<s1.length();n++){             proc=new procesare(this,cuv[n],n);         }      } }

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
