[lazarus] How to scroll TMemo control in code

Tue Apr 8 18:47:54 EDT 2003

Ha ha .... this is a problem. I am not doing cvs in Linux. I am using WinCVS
under windows and I tranfer the files into the Linux partition. Any idea how to
do this?

The IDE has no cvs commands yet.

Just open a terminal and do

cd lazarus
cvs -z3 diff -u | gzip > laz.diff.gz

type
  TStringText = class(TStrings)
  private
    fStr: string;
    ...
  end;

see TStrings
add some useful procedures like GetTextLength, GetLineBounds, InsertText,
DeleteText, ReplaceText, MoveText, SearchText, ... and override any
inherited method from TStrings that should access fStr.
