funcionalidad en xBrowse

[lucasdebeltran]

Hola,

Me gustaría saber cómo guardar la configuración de columnas de xBrowse cuando se hace click derecho y se desmarcan algunas columnas, de modo que la próxima vez que se inicie dicho xBrowse sólo se cargen las que el usuario ha marcado.

cState := oBrw:SaveState()

Save the value of cState in any file on disk.

Next time when the program is run, read the value of cState and restore it by oBrw:RestoreState( cState ), after completely defining the browse.

And for all columns?.

The idea is let the user to choose the columns that he needs to be shown.

Thank you.

Yes. This saves the information of all columns about their status of visibility, position and widths

Great.

And where I place savestate and loadstate?.

Thank you.

Please try this sample

Code: Select all  Expand view

#include "FiveWin.Ch"
#include "xbrowse.ch"

//----------------------------------------------------------------------------//

REQUEST DBFCDX

//----------------------------------------------------------------------------//

function Main()

   local oDlg, oBrw, cState, cFile := "xbrstate.txt"

   USE CUSTOMER
   DEFINE DIALOG oDlg SIZE 600,400 PIXEL
   @ 10,10 XBROWSE oBrw SIZE -10,-10 PIXEL OF oDlg ;
      AUTOCOLS ALIAS "CUSTOMER" CELL LINES NOBORDER

   oBrw:CreateFromCode()

   if File( cFile )
      cState   := MemoRead( cFile )
      FErase( cFile )
      oBrw:RestoreState( cState )
   endif

   ACTIVATE DIALOG oDlg CENTERED ;
      VALID ( MemoWrit( cFile, oBrw:SaveState() ), .t. )

return (0)

Hello.

It works perfect with FW 11.08 + Harbour 2.x.

Would be possible to implement a global set to handle this automatically?.

A.e., SET XBROWSESAVESTATE ON

And info coud be stored in the same .ini. For every xBrowse, section could be the name of the function where xbrowse is called.

I think it is a very interesting feature.

Thank you.

It is better to leave it to the programmer.
Different programmers may have different preferences to to store the saved state. You may like to save in ini file, some others somewhere else.

[lucasdebeltran]

In that case, the programer can edit that function to adapt to his needs.

But in general, saves many time of coding.

Mr Nao,

Could be possible ?

Thanks
