How Drawmenu work's?

[compsystems]

ok Quit function works fine, a delay is required, so the menu does not print n times.

PHP Code:

callit(F)
BEGIN
  IF F=="" THEN RETURN; END;
  EXPR(F);
  draw();
  wait(0.2);
END; 


But unfortunately there is not function to return to the terminal view =(, I hope that some developer will incorporate a function to goto the terminal view (terminalView(); ), also it requires a vertical AutoScroll, otherwise the terminal view is not useful After the first screen. Do you agree with this?

please test Menu5 [choose] and menu4 [printScroll] n times

PHP Code:

//PHP for highlight
#pragma mode( separator(.,;) integer(h32) )
local stay;
EXPORT LibMenuTest()
BEGIN
  stay:=1;
  print();
  print("test menu on terminal view"); freeze;
  LibMenu.reset();
  entry(1,"print1","tstLibM.f1()");
  entry(2,"print2","tstLibM.f2()");
  entry(3,"print3","tstLibM.f3()");
  entry(4,"printScroll","tstLibM.f4()");
  entry(5,"choose","tstLibM.f5()");
  entry(6,"exit","tstLibM.quit()");
  LibMenu.draw();
  WHILE stay DO
   LibMenu.events();
  END;
  return "Done";
END;

f1()
BEGIN
  print("expr1: a/b"); LibMenu.draw(); 
END;

f2()
BEGIN
  print("expr2: x^2"); LibMenu.draw(); 
END;

f3()
BEGIN
  print("expr3: abs(-x)"); LibMenu.draw();
END;

f4()
BEGIN
  print("string: 1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz123​4567890abcdefghijklmnopqrstuvwxyz"); LibMenu.draw();
END;

f5()
BEGIN
 MSGBOX("popup dialog box"); // terminalView();
 LibMenu.draw();
END;

EXPORT quit()
BEGIN
 stay:=0; // you will quit nicely the WHILE loop
END;
