BeginUndoBlock and EndUndoBlock of SynEdit

[Edson]

Are these methods:

BeginUndoBlock and EndUndoBlock

enabled in SynEdit?

If so, How do they work?

[Martin_fr]

yes they are.

Code: [Select]

BeginUndoBlock;
//call edit
//call edit
//...
EndUndoBlock;

All edits will be undone in a single undo.
Without the undoblock, each edit requires one undo

Please read:
http://wiki.lazarus.freepascal.org/SynEdit#Change_text_from_code

access to SynEdit.Lines never works with undo

Thanks Martin,

I haven't found information about these methods of SynEdit.

The wiki is a little poor about SynEdit.

In fact, I have started to complete the spanish version: http://wiki.freepascal.org/SynEdit/es

[Martin_fr]

well yes, documenting synedit is still a big todo.

but the methods should be self explaining. Use code navigation, and you will see the declaration.

SynEdit.TextBetweenPoints[ Point(x,y), Point(x2,y2) ] := 'abc';

works like setting block-selection begin/end and then SelText := 'abc'

x,y are "logical". see same wiki page
