Description
Use the OnProcessData event handler to write code that responds when a data buffer is received.
Write your custom code to process the data inside the event. The incoming data will be contained inside the InBuffer. You can assign the processed data to the OutBuffer.
You can prevent the output buffer to be sent to the next component by setting SendOutputData to False.
Usually occurs when a new data buffer is generated during data capturing or data playback.
Delphi Example:
// Plot the buffer data
procedure TForm1.SLGenericReal1ProcessData(Sender: TObject;
InBuffer: ISLRealBuffer; var OutBuffer: ISLRealBuffer; var SendOutputData: Boolean);
var
I : Integer;
begin
Chart1.Series[ 0 ].Clear();
for I := 0 to InBuffer.GetSize() - 1 do
Chart1.Series[ 0 ].Add( InBuffer.Items[ I ], , clRed );
end;
C++ Builder Example:
// Plot the buffer data
void __fastcall TForm1::SLGenericReal1ProcessData(TObject *Sender,
TSLCRealBuffer InBuffer, TSLCRealBuffer &OutBuffer,
bool &SendOutputData)
{
Chart1->Series[ 0 ]->Clear();
for( int i = 0; i < InBuffer.GetSize(); i ++ )
Chart1->Series[ 0 ]->Add( InBuffer[ i ], "", clRed );
}
Visual C++ Example:
// Plot the buffer data
void __stdcall CCustomFilterDemoDlg::SLGenericReal1FilterData(void *Sender,
TSLCRealBuffer InBuffer, TSLCRealBuffer &OutBuffer,
bool &SendOutputData)
{
for( int i = 0; i < InBuffer.GetSize(); i ++ )
{
double Value = InBuffer[ i ];
// Plot the Value with your favorite chart component.
}
}
