Class definition advice needed. (SOLVED)

[Horizon]

Dear Masters,

I have an browse class name TYK_List. I have an define line like above.

Code: Select all  Expand view  RUN

CLASS TYK_List FROM TYK_Core

    DATA oData
    DATA oDlg, oDlg_Other
    DATA oParent
    ....
    ....
    ....

    METHOD New( cVarName, cCerID, uData, aMyCols, aHeaders, cButtonPlace, SART, ARANAN, nOrd, aButtons, ;
            aRelations, aOptions, Esas_Isim, Ex_SART, aCargo, cSilKontrol, cOnBody, aArama, oData, ;
            lLineNo, cOnExtra_Caption, oApp, oFont_Brw, oFont_Edit, ldontExit, aStartUp, bOzelyetki, ;
            bOnLocked, cOnLocked, lDesc, lMultiSelect, oWnd, oParent, cPrefix_Sil, aKaydet_Kontrol, ;
            cTitle, cOnExtra_Bitmap, cIcon) CONSTRUCTOR
   
       
    METHOD GO_DETAY_Ekle()
    METHOD GO_DETAY()
    METHOD GO_SIL()
    METHOD GO_BUL()
    ....
    ....
    ....
   
    METHOD End()

ENDCLASS   
 

Code: Select all  Expand view  RUN

#xcommand DEFINE Ob_Browse1 <oOb_Brw> [OF <oWnd>];
                        [ CERCEVEID <cCerID> ] ;
                        [ UDATA <uData> ] ;
                        [ DATA <oData> ] ;
            [ <cols: COLS, COLUMNS> <aMyCols,...> ] ;
            [ <head:HEAD,HEADER,HEADERS> <aHeaders,...> ] ;
                        [ BUTTONYERI <cButtonPlace> ] ;
                        [ SART <cSART> ] ;
                        [ ARANAN <cARANAN> ] ;
                        [ ORDER <nOrd> ] ;
            [ <buttons:BUTTON, BUTTONS> <aButtons,...> ] ;
            [ <rela:RELATION, RELATIONS> <aRelations,...> ] ;
            [ <opt:OPTION, OPTIONS> <aOptions,...> ] ;
                        [ ESASISIM <cEsas_Isim> ] ;
                        [ EXTRASART <Ex_SART> ] ;
                        [ CARGO <uCargo> ] ;
                        [ ONSILKONTROL <cSilKontrol> ] ;
                        [ ONBODY <cOnBody> ] ;
            [ <aramavar: ARAMAVAR> <aAramaVar,...>] ;
            [ <lineno: LINENO> ] ;
                        [ EXTRABUTTON CAPTION <Ex_BCaption> ] ;
                        [ EXTRABUTTON BITMAP <Ex_BBitmap> ] ;
                        [ TITLE <cTitle> ] ;
                        [ APPLICATION <oApplication> ] ;
                        [ BROWSE FONT <oFont_Brw> ];
                        [ EDIT FONT <oFont_Edit> ];
                        [ PARENT <oParent> ] ;
            [ <ldontExit: DONTEXIT> ] ;
            [ STARTUP <aStartUp>] ;
            [ OZELYETKI <bOzelYetki>] ;
            [ ONLOCKED <bOnLocked>] ;
            [ ONLOCKED_VAR <cOnLocked>] ;
                        [ <lDesc: DESCENDING> ] ;              
                        [ <lMulti: MULTISELECT> ] ;            
                        [ PREFIX_SIL <cPrefix_Sil> ] ;
            [ <KONTROL> <aKontrols,...> ] ;
      => ;
          <oOb_Brw> := TYK_List():New(<(oOb_Brw)>, <cCerID>, <uData>, ;
                        [\{<aMyCols>\}],;
                        [\{<aHeaders>\}],;
                        [<cButtonPlace>],[<cSART>],[<cARANAN>],[<nOrd>],;
                        [<aButtons>],[\{<aRelations>\}],[<aOptions>],[<cEsas_Isim>],;
                        [<Ex_SART>],[<uCargo>],<cSilKontrol>,<cOnBody>,[<aAramaVar>], ;
                        <oData>, <.lineno.>, [<Ex_BCaption>], <oApplication>,;
                        [<oFont_Brw>], [<oFont_Edit>], <.ldontExit.>, <aStartUp>, <bOzelYetki>, ;
                        <bOnLocked>, <cOnLocked>, <.lDesc.>, <.lMulti.>, [<oWnd>], [<oParent>],;
                        [<cPrefix_Sil>], [\{<aKontrols>\}], [<cTitle>], [<Ex_BBitmap>] )
                   

This class has a dialog and can be define more than one same class in it. There is no problem. It works.

If there is an error in one dialog that called from first class, I could not found the which derived object is from.

I have decided to separate class like This

Code: Select all  Expand view  RUN

CLASS TMy_Purpose1 FROM TYK_List
ENDCLASS   

CLASS TMy_Purpose2 FROM TYK_List
ENDCLASS   

CLASS TMy_Purpose3 FROM TYK_List
ENDCLASS   

CLASS TMy_Purposen FROM TYK_List
ENDCLASS   

In this situation, I can not use define "Ob_Browse1" name. I should define every inherited class "TMy_Purpose?". But This class is constantly changing, it also defines.
I should not forget to change inherited class defines also.

Question :

Is there any general define method (or parameter) to run inherited classes from one define line?

Code: Select all  Expand view  RUN

xcommand DEFINE oMy_Purpose1        oOb_Browse1         // but should run TMy_Purpose1() instead TYK_List()

Please try this sample and adapt to your requirements:

Code: Select all  Expand view  RUN

#include "fivewin.ch"

#xcommand DEFINE <o> Ob_Browse1  <n> [SUBCLASS <cClass>] => ;
   <o> := HB_ExecFromArray( IfNil( <cClass>, "TYK_LIST" ) ):New( <n> )

function Main()

   local o, o1, o2, O3

   DEFINE o  Ob_Browse1  1
   DEFINE o1 Ob_Browse1  1 SUBCLASS "TMY_PURPOSE1"
   DEFINE o2 Ob_Browse1  1 SUBCLASS "TMY_PURPOSE2"
   DEFINE o3 Ob_Browse1  1 SUBCLASS "TMy_Purpose3"

   ? o:ClassName(), o1:ClassName(), o2:ClassName(), o3:ClassName()

return nil

CLASS TYK_List
ENDCLASS

CLASS TMy_Purpose1 FROM TYK_List
ENDCLASS

CLASS TMy_Purpose2 FROM TYK_List
ENDCLASS

CLASS TMy_Purpose3 FROM TYK_List
ENDCLASS

CLASS TMy_Purposen FROM TYK_List
ENDCLASS

Thank you very much Mr. Rao,

This solved my problem.
