TMemo force scrolling to bottom

[Чебурашка]

Hello,
I have a TMemo used to display a log that grows because of a ongoing background process. I would like to make sure last line appended is always visible, I was thinking to programmatically set the position of the vscrollbar to max but I don't find a way to do that, so probably my idea isn't working.

How can I get this working?

How can I get this working?

Should work out of the box on Windows. For Linux I use:

Code: Pascal  [Select][+][-]

1.   Memo1.Append('some string');
2.   {$ifdef linux} // fix gtk bug not updating memo scroll
3.   Memo1.selstart := MaxInt;
4.   {$endif}
5. end;
6.  

Not my idea but from a fellow forum user (sorry as I can't remember who it is).

Are you doing some additional setting, maybe in the object inspector? I tried this but it doesn't do

This worked for me:

Code: Pascal  [Select][+][-]

1.   MemoLog.SelStart := Length(MemoLog.Text);
2.

Nope. Nothing at all.

the lfm looks like:

Code: [Select]

  object Memo1: TMemo
    Left = 16
    Height = 183
    Top = 8
    Width = 336
    Lines.Strings = (
      'Memo1'
    )
    TabOrder = 0
  end


This worked for me:

Code: Pascal  [Select][+][-]

1.   MemoLog.SelStart := Length(MemoLog.Text);
2.  

That is strange. I used to do it like that as well but since the maxint is automatically corrected by the underlying widget implementation it should work. I am using Lazarus 2.2.6 GTK widgetset on Debian Bookworm, Mate desktop.

Thank you for reporting back as I wasn't aware. Probably something that changed overtime in the widget implementation I assume.

Prob is bcz I am using qt5 widgets

Ah, yes that might be a reason for it.

I am not very experienced with all different widgetsets (I hardly have any knowledge about qt5 and Lazarus).
