Fivewin OOP Question

[Jimmy]

hi,

when using #xCommand Syntax in CLASS like this

Code: Select all  Expand view  RUN

LOCAL oText_2, cTargetDir

   DEFINE WINDOW oASKFORM FROM 0,0 TO 270, 534 PIXEL TITLE cAction
   @ 110,10 GET oText_2 VAR cTargetDir SIZE 500,30 PIXEL FONT oFontDefault OF oASKFORM
 

will VAR "cTargetDir" be Property of oText_2

if YES
can write

Code: Select all  Expand view  RUN

  ::oASKFORM:oText_2:cTargetDir := cDir + "\"

or must i pass "cTargetDir" as Parameter

Code: Select all  Expand view  RUN

  cTargetDir := cDir + "\"

[Enrico Maria Giordano]

No, oASKFORM, oText_2 and cTargetDir are independent variables. Please note that you should define LOCAL oASKFORM too.

hi Enrico,

Ok, understand
so i have to make a own CLASS and use CLASS Code / DATA when i do not want to pass Parameter

---

have forgot to say that i have DATA oASKFORM and made this

Code: Select all  Expand view  RUN

  ::oASKFORM := oASKFORM

but still my Question about Object and "OF Parent"
when assign Object to a Parent, a Parent should know it´s Child

i have try first

Code: Select all  Expand view  RUN

 ::oASKFORM:oText_2:cTargetDir := cDir + "\"  -> crash

Ok, "cTargetDir" is a LOCAL Variable and not a Property

so i try just

Code: Select all  Expand view  RUN

  xxx := ::oASKFORM:oText_2

but still got

Message not found: TWINDOW:OTEXT_2

so not ::oASKFORM is "Parent" but "Super-CLASS" TWINDOW

---

under Xbase++ all Control of XbpDialog ( WINDOW / DIALOG ) are Child so you can use

Code: Select all  Expand view  RUN

   ::oParent:oChild_1

under HMG i use "OF" or "PARENT" and can use "semi-OOP" Syntax

Code: Select all  Expand view  RUN

   oParent.oChild_1

now i have to learn new how to use OOP and what "OF" mean under Fivewin

[Enrico Maria Giordano]

so i try just

Code: Select all  Expand view  RUN

  xxx := ::oASKFORM:oText_2

but still got

Message not found: TWINDOW:OTEXT_2

Of course: oText_2 is not a property of oASKFORM, it is a local variable! I think you should have to carefully read a good book about OOP.

hi,

Of course: oText_2 is not a property of oASKFORM, it is a local variable!

right but i use "OF" which work under HMG "as expect" using "semi-OOP" Syntax

I think you should have to carefully read a good book about OOP.

sorry, it work that Way under Xbase++ and HMG so why not under Fivewin

p.s. i did work with OOP and Xbasse++ over 20 Year and 3 Year with HMG

[Enrico Maria Giordano]

Beacuse FWH is better OOP design, what else?

[Jimmy]

hi Enrico,

i can´t talk about Fivewin OOP yet while have not made enough CODE

i have learn using "OF" under HMG and it work like OOP
you also can use

Code: Select all  Expand view  RUN

SetProperty()
GetProperty()
DoMethod()

like ActiveX OOP which work under every Language

---

i have hope to use #xCommand Syntax in Fivewin CLASS but it seems not good to mix it with CLASS Code
i´m still a Newbie under Fivewin and have a lot to learn.

but i "think" also Fivewin can learn what "other" is doing like "semi-OOP" Style using "OF" / "PARENT"
it would be nice to have when become use to it

p.s. have still not figure out how HMG / Extended Version does "semi-OOP" Style

Jimmy,

Maybe this link can give you some insite : It is from Mr. James Bott (Mr. OOP for me ) James, with respect !!

Something like this?

Code: Select all  Expand view  RUN

#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oDlg

    #ifdef __XHARBOUR__
        EXTEND CLASS TDialog WITH MESSAGE Test INLINE Test()
    #else
        __CLSADDMSG( TDialog():classH, "Test", { || Test() }, HB_OO_MSG_INLINE )
    #endif

    DEFINE DIALOG oDlg

    @ 1, 1 BUTTON "Test";
           ACTION oDlg:Test( "Hello" )

    ACTIVATE DIALOG oDlg;
             CENTER

    RETURN NIL


STATIC FUNCTION TEST()

    ? "Hello"

    RETURN NIL

hi Enrico,

Something like this?

interesting Code
do it work in MDI Environment as i see no "OF" / "PARENT" Keyword

It should work with any objects.
