Possible to run 2 or 3 browser synchronously ?

[ukoenig]

Hello,

is it possible to show the same cell-/row-position of browser 1 in browser 2 ?
I explain :
Browser 1 shows the 12 month-values of 2017
Browser 2 shows the 12 month-values of 2016 using the same structure.
I have to check the values of 2017 in relation to 2016
Selecting something in browser 1, next I have to move to browser 2 to check the same month and cell-value.
It would be nice if changing the position in browser 1, browser 2 would move to the same position ( row / Col ).



Sample :
Moving with the right arrow to the last column ( 27 ) and showing the totals of a month



REDEFINE BTNBMP oBtn9 OF oFld:aDialogs[ 2 ] ;
ID 340 PIXEL ;
BORDER ;
FILENAME c_Pfad1 + "Rechts.Bmp" ;
ACTION ( oBrw2:SelectCol( 21, .T. ), oBrw2:Refresh(), ; // works
oBrw3:SelectCol( 21, .T. ), oBrw3:Refresh() ) ; // doesn't work
RIGHT
oBtn9:cToolTip = { "Spalten" + CRLF + "Ende","LISTE", 1, CLR_BLACK, 14089979 }
oBtn9:SetColor( 0, )
oBtn9:lTransparent := .T.

tested to move to the column of browser 2 the same column like browser 1
but doesn't work

WITH OBJECT oBrw2
:bChange := { || nCPos := oBrw2:SelectedCol():nCreationOrder, ;
oBrw3:SelectCol( nCPos, .T. ), oBrw3:Refresh() } // move to column-pos of browser 1 doesn*t work
END

Uwe,

Can you just move oBrw3 to a different column and refresh it?

Did you use the oBrw3...of oDlg clause?

Just random ideas.

Uwe,

this is a bit tricky, but this might work:

Code: Select all  Expand view

    oBrw1:bChange := {|| oBrw2:PostMsg( WM_KEYDOWN )}
    oBrw2:bChange := {|| oBrw1:PostMsg( WM_KEYDOWN )}
    oBrw1:lColChangeNotify := .t.
    oBrw2:lColChangeNotify := .t.
    oBrw1:OnKeyDown := {|| oBrw1:SelectCol(oBrw2:SelectedCol():nCreationOrder), oBrw1:Refresh()}
    oBrw2:OnKeyDown := {|| oBrw2:SelectCol(oBrw1:SelectedCol():nCreationOrder), oBrw2:Refresh()}
 

I'm still grateful to Antonio for giving me the tip of using PostMsg!!!

[ukoenig]

thank You very much

Gilbert,
Your solution works fine but only inside the visible area at startup.
Moving to other fields there is a problem

The test for download
I used customer.dbf as customer1.dbf and customer2.dbf ( same contens ) for the test

http://www.pflegeplus.com/DOWNLOADS/Sync.zip

works at startup on visible fields and selects row and col on second browser



The record-position works but the column of browser 2 doesn't move

Uwe,

sorry, I neglected one of your parameters from the example, this works with me (forgot the .t.):

Code: Select all  Expand view

oBrw1:OnKeyDown := {|| oBrw1:SelectCol(oBrw2:SelectedCol():nCreationOrder, .t.), oBrw1:Refresh()}
oBrw2:OnKeyDown := {|| oBrw2:SelectCol(oBrw1:SelectedCol():nCreationOrder, .t.), oBrw2:Refresh()}

But the view isn't exactly the same, as scrolling isn't synchronously.

[ukoenig]

Gilbert,

much better ( sample updated ).

But the view isn't exactly the same, as scrolling isn't synchronously.

As long the field is the same it is ok ( no need to search for the position in browser 2 anymore )
The solution is needed to check statistic-values between different years.

Uwe

Please try this.

Code: Select all  Expand view

#include "fivewin.ch"

function Main()

   local oDlg, oBrw1, oBrw2

   USE CUSTOMER NEW ALIAS CUST1 SHARED
   USE CUSTOMER NEW ALIAS CUST2 SHARED

   DEFINE DIALOG oDlg SIZE 800,800 PIXEL TRUEPIXEL ;
      TITLE "TWIN BROWSES"

   @  20,20 XBROWSE oBrw1 SIZE -20,380 PIXEL OF oDlg ;
      DATASOURCE "CUST1" AUTOCOLS ;
      CELL LINES NOBORDER

   @ 400,20 XBROWSE oBrw2 SIZE -20,-20 PIXEL OF oDlg ;
      DATASOURCE "CUST2" AUTOCOLS ;
      CELL LINES NOBORDER

   oBrw1:lColChangeNotify  := .t.
   oBrw1:bGotFocus   := { || SyncBrowses( oBrw1, oBrw2 ) }
   oBrw1:bChange     := { || If( oBrw1:lFocused, SyncBrowses( oBrw1, oBrw2 ), nil ) }

   oBrw2:lColChangeNotify  := .t.
   oBrw2:bGotFocus   := { || SyncBrowses( oBrw2, oBrw1 ) }
   oBrw2:bChange     := { || If( oBrw2:lFocused, SyncBrowses( oBrw2, oBrw1 ), nil ) }

   oBrw1:CreateFromCode()
   oBrw2:CreateFromCode()

   ACTIVATE DIALOG oDlg CENTERED

return nil

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

function SyncBrowses( oBrw1, oBrw2 )

   WITH OBJECT oBrw2
      :BookMark      := oBrw1:BookMark
      :nRowSel       := oBrw1:nRowSel
      :nColSel       := oBrw1:nColSel
      :nColOffset    := oBrw1:nColOffset
      //
      :Refresh()
   END

return nil
 

Navigation in either browse is replicated in the other browse.

Mr. Rao,

thank You very much for the sample.
It works fine and keeps the row- and col-positions.

I added this sample to my sample-collector with some more options / tests.
1. Moving to browser top, left, bottom and right on button-action.
2. added a seekbar to browser 1 and 2
The sample displays 2 browser from resources

I noticed that the seekbar on browser 2 is not displayed.
Typing something in browser 2, the seek works

Mr. Rao,

my new project is a little bit more complicated
I have a file splitted in 3 browser-sections ( each section = 1 browser )
Browser 3 shows a horizontal scrollbar
NO vertical synchronous needed !!!

The file is splitted in 3 sections
each section is filtered to group and section

oProj := TDatabase():Open( , "PROJECT", "DBFCDX", .T. )
oProj:CreateIndex( "PROJECT", "PROJ1", "Group + Section + Position", .F. )
oProj:Close()
oProj1 := TDatabase():Open( , "PROJECT", "DBFCDX", .T. )
oProj1:SetOrder( "PROJ1", "PROJECT" )
oProj2 := TDatabase():Open( , "PROJECT", "DBFCDX", .T. )
oProj2:SetOrder( "PROJ1", "PROJECT" )
oProj3 := TDatabase():Open( , "PROJECT", "DBFCDX", .T. )
oProj3:SetOrder( "PROJ1", "PROJECT" )

is it possible to show all 3 browsers horizontal synchronous using the logic from above ?
the scrollbar belongs to all three browser

each browser is filtered like

oProj1:ORDSCOPE(0, NIL ) // reset
oProj1:ORDSCOPE(1, NIL ) // reset
oProj1:ORDSCOPE(0, "A1" ) // set top scope B1, C1 = group + section
oProj1:ORDSCOPE(1, "A5" ) // set bottom scope B5, C5
oProj1:GoTop()

3 Groups, 5 sections and 7 positions each section
with the radios You can select / display a full section without seek



the same is used to collect and connect to useful topics from the forum
splitted in different groups total < 3 x 5 x 7 > ( 5 can be extended )



best regards
Uwe

tested and works

to cover all possible combinations of 3 browser :

Code: Select all  Expand view

oBrw1:lColChangeNotify  := .t.
oBrw1:bGotFocus         := { || Sync( 1, oBrw1, oBrw2, oBrw3 ) }

oBrw2:lColChangeNotify  := .t.
oBrw2:bGotFocus         := { || Sync( 2, oBrw1, oBrw2, oBrw3 ) }
oBrw2:bChange           := { || If( oBrw2:lFocused, Sync( 2, oBrw1, oBrw2, oBrw3 ), nil ) }

oBrw3:lColChangeNotify  := .t.
oBrw3:bGotFocus         := { || Sync( 3, oBrw1, oBrw2, oBrw3 ) }
oBrw3:bChange           := { || If( oBrw3:lFocused, Sync( 3, oBrw1, oBrw2, oBrw3 ), nil ) }

//----------------------  

FUNCTION SYNC( nBrw, oSBrw1, oSBrw2, oSBrw3 )

IF nBrw = 1
    oSBrw2:nColSel      := oSBrw1:nColSel
