How to scroll to a specific location in a TMemo

[Jim K]

So I know how to do this in Delphi/CBuilder but I can't seem to find a way to do this in Kylix.

In Delphi the following code would make a TMemo scroll to a specific location, in this case the 5th line from the top.
with Memo1 do
begin
SelStart := Perform(EM_LINEINDEX, 5, 0);
Perform(EM_SCROLLCARET, 0, 0);
end;

In Kylix TMemo.Perform doesn't exist. Any suggestions on how to do this would be appriciatied.

You might try:

var Cp:TCaretPos;

...

Cp.Col:=0;
Cp.Line:=5;
SampleMemo.CaretPos:=Cp;

This ensures that the cursor position is visible.

Or you might take a TSynEdit (or TSynMemo) for more control. (see
Topline property)

Changing the CaretPos works but if the file is too large the performance can be pretty bad. I'll look into the TSynMemo and thanks for the tip.
