MOUSE command CLICK type

[Carlos295pz]

Working with MOUSE, GETKEY and ISKEYDOWN is only recommended when requiring animations or similar, as in games, otherwise it is more optimal to work with WAIT (-1).

I have not yet written an article on interface creation, but I have published a short introduction at the end of a graphic article: Introduction to GUIs (Spanish).

If you want to explore WAIT(-1), try this code:

Code:

EXPORT WAIT_1_TEST
BEGIN
 RECT;
 LOCAL dat,ctr;

 REPEAT

  dat:=WAIT(−1);

  RECT;
  ctr:=ctr+1;
  TEXTOUT_P(dat,20,50,2); //Imprime lo retornado por WAIT(-1)
  TEXTOUT_P(ctr,20,65,2); //Un contador de repeticiones del bucle

  //wait(.5); //Activar para observar eventos intermedios.

 UNTIL 0;
END;

It is not necessary to convert the coordinates # 0:-16h to real data, you can compare them directly without problems. Using ISKEYDOWN or GETKEY can cause operating problems in WAIT (-1), however its use ends up being unnecessary.
