** ListBox column in the XBROWSE

[shri_fwh]

** ListBox column in the XBROWSE
When ListBox column get focused in the XBROWSE control and user select one of an Item from the list by pressing
Entry key the control focus is moving to the GET item ( aGET[1] ) whereas the control focus should get next column of the XBROWSE.

Please guide me. I am new to FWH. thanks in advance.

Sample Code here :

procedure billentry

local aGet := array(5)
local oBrw
local aBill := {'Floppy','Pcs', 10, 40}
local cCustName := space(30)

define dailoag oDlg from 0,0 to 24,79 title "List Box Test"


@10,10 get aGet[1] var cCustName pict "@!"

@20,05 XBROWSE oBrw ;
COLUMNS 1,2,3,4,5 ;
HEADERS 'Item','Unit','Qty','Rate';
SIZE 200,100 OF oDlg

WITH OBJECT oBrw:Unit
:nEditType := EDIT_LISTBOX
:aEditTxtList := {"BOX","PCS","DOZ"}
END

oBrw:createfromcode()
// ... some other code to attach to oDlg

active window oDlg on init oBrw:setfoucs()

return nil

Shridhar,

Please try it this way:

Code: Select all  Expand view

   ACTIVATE DIALOG oDlg ON INIT ( oBrw:Setfocus(), ADel( oDlg:aControls, 1 ), .F. )

The same problem facing even after adding this code. I will send the exact source. thanks in advance.

Mr. Shri

Can you post here simple code, that compiles correctly and runs without runtime errors?

Hi Nagesh,

I am sorry too late for post the code. I was busy in office project. Please see below source code.

Problem description : Navigation between GET and TXBRowse control.
In the below code first control focus goes to GET object ( cAccountName ) and it moves to TXBRowse Control.
When user select an item and enter Rate value after the control moves to List Box Column (KG,BOX,PCS). Here when user select an item form ListBox column control focus moves to the GET object ( cAccountName ) where as it should moves to next column of the TXBrowse whic 'Quantity' Column.


Thanks
Shridhar
