UniHTMLMemo autoscroll

[stiaan]

Hi

 

Can anybody please assist:

I'm busy developing a UniGUI system that captures the realtime output of a console application and is then displayed it in a TUniHTMLMemo control. I need to be able to scroll as the text comes in from the console app.

 

The application successfully captures the output, but I need to scroll and show the latest line.

 

Much appreciated!

Hi,

 

You can use ScrollBars property of TUniHTMLMemo to deal with scroll. There you can supply ssBoth, ssNone, ssHorizontal or ssVirtical.

Hi

 

Thanks for the reply, but I'm looking more for the ability to scroll programmatically to the last line.

scroll programmatically to the last line.

 

Hi,

 

For now try:

procedure TMainForm.UniButton1Click(Sender: TObject);
var
  HTMLMemoJSName: string;
begin
  HTMLMemoJSName := UniHTMLMemo1.JSName;
  UniHTMLMemo1.Lines.Add('scroll programmatically to the last line... ');
  UniSession.AddJS('setTimeout(function(){' + HTMLMemoJSName + '.iframeEl.dom.contentWindow.scrollTo(0, ' +
                    HTMLMemoJSName + '.iframeEl.dom.contentWindow.document.body.scrollHeight)}, 50)');
end;

Best regards.
