TXBrowse - oBrw:GoBottom() in the init clause

TXBrowse - oBrw:GoBottom() in the init clause

Postby nageswaragunupudi » Sat Jan 12, 2008 5:18 am

Our users insist that the last portion of the data be shown in the browse to start with ( for financial data like ledgers, daybooks, etc ) because they are more interested in seeing the latest information to start with.

I use code something like "activate dialog odlg on init ( obrw:gobottom(), obrw:setfocus() )"

This works well if the browse is in dialog but not when the browse is in window. But our requirement is to present the browses in mdi child windows (not in dialogs) because the users want to open two or three accounts simultaneously for comparison.

In the case of dialog the last rows of the data are filled fully in the browse area and the cursor is positioned on the last row. But in the case of window, only the last 2 or 3 lines are displayed at the top leaving the rest of the browse area blank. Here is an example to show the difference in behavior of xbrowse in dialogs and windows.
Code: Select all  Expand view
#include 'fivewin.ch'
#include 'xbrowse.ch'

function main()

local ownd, obar

   define window ownd mdi
   define buttonbar obar of ownd
   define button of obar prompt 'dlg' action xbrdlg()
   define button of obar prompt 'win' action xbrwin()

   activate window ownd

return nil

static function xbrdlg()

local odlg, obrw

   use \fwh\samples\customer new alias cust1 shared

   define dialog odlg size 800,600 pixel
   obrw := txbrowse():new( odlg )
   obrw:calias := 'cust1'

   obrw:ntop     := 10
   obrw:nleft    := 10
   obrw:nbottom  := 290
   obrw:nright   := 390

//   obrw:setrdd()
   obrw:createfromcode()

   activate dialog odlg centered ;
      on init ( obrw:gobottom(), obrw:setfocus() )
   close cust1

return nil

static function xbrwin()

local ownd, obrw, calias

   calias := cgetnewalias( 'cust' )
   use \fwh\samples\customer new alias (calias) shared

   define window ownd mdichild of wndmain()
   obrw := txbrowse():new( ownd )
   obrw:calias := calias
   obrw:createfromcode()
   ownd:oclient := obrw

   activate window ownd ;
      on init ( obrw:gobottom(), obrw:setfocus() ) ;
      valid ( (calias)->(dbclosearea()), .t. )

return nil

I could find out the reason, but I could not find solution. In case of dialog the browse object knows the correct value of obrw:nheight and consequently the method obrw:brwheight returns the correct value, because we assign the value to data nbottom initially. In case of window, the browse object does not know the correct height information at the time of "on init" of window.

How can this be solved please?

I just found this works:
Code: Select all  Expand view
activate window ownd on init ( obrw:nheight := ownd:nheight, obrw:gobottom(), obrw:setfocus() )
