Re: [amibroker] Re: synchronised scrolling

Here's a "solution" posted by BruceR:
 
Put in formula:

UseZoomer = ParamToggle("Use Zoomer?", "No|Yes", 0);
#include_once <Zoomer_Include_File.afl>
 
 
put the below into your include directory:
 
//--------------------------------------------------------------------------------------------------
//
//  This function checks the current display range, and if it has changed, it
//  synchronizes all other windows (documents) to that range.
//
//  To use, #include this file in an indicator in each window (document) to be
//  synchronized.  Normally it sync's other windows (documents) when the caller's
//  displayed date range changes, but it has an optional parameter to force a re-sync.
//
//  NOTE - the only downside is that the blank bars on the right side are
//         removed by the ZoomToRange method
//

function ZoomSync( force )
{
   //  All variables are made local to guarantee naming collisions or side effects
   local bv, dr, Curstdt, Curenddt, prevstdt, prevenddt, Curststr, Curendstr;
   local OAB, OAD, dcount, i, OADoc, OAW, OADocWin, res;
   //  Get a count of the number of documents
   OAB = CreateObject( "Broker.Application" );
   OAD = OAB.Documents;
   dcount = OAD.Count;
   //  Process multiple windows (documents)
   res = False;
   if ( dcount > 1 )
   {
       //  Get current and last start and end DateTimes's
       bv = Status( "barvisible" );
       dt = DateTime( );
       Curstdt = LastValue( Lowest( IIf( bv, dt, LastValue( dt ) ) ) );
       Curenddt = LastValue( Highest( IIf( bv, dt, 0 ) ) );
       prevstdt = Nz( StaticVarGet( "_prevstdt" ) );
       prevenddt = Nz( StaticVarGet( "_prevenddt" ) );
       //  Check for a new date/time range
       if ( ( Curstdt != prevstdt OR Curenddt != prevenddt ) OR force )
       {
           //  Set the new last values
           StaticVarSet( "_prevstdt", Curstdt );
           StaticVarSet( "_prevenddt", Curenddt );
           Curststr = DateTimeToStr( Curstdt );
           Curendstr = DateTimeToStr( Curenddt );
           //  Loop through the document collection
           for ( i = 0; i < dcount; i++ )
           {
               //  If it is not the active document -
               OADoc = OAD.Item( i );
               //  NOTE - it doesn't hurt to sync the current window and it makes all
               //         windows have no blank bars on the right so they look the same
               //if ( OADoc != OAB.ActiveDocument )
               {
                   //  Get the document window and zoom to range
                   //_TRACE( "  Zoom to range document - " + i + " , " +   Curststr + " - " + Curendstr );
                   OADW = OADoc.Windows;
                   //  Document window count assumed to be 1
                   OADocWin = OADW.Item( 0 );
                   OADocWin.ZoomToRange( Curststr, Curendstr );
               }
           }
           res = True;

   return res;

//  Call for synchronization
