Hi Scott,
As already pointed out by Valery, the solution to your problem is to use
TPaveText::ReadFile. Also note that in version 2.20, I added several
features in the TPaveText context menu to
- add one line of text anywhere inside the TPaveText
- edit one line
- delete one line
- change attributes (SetAllWith)
These functions are still quite primitive. I am waiting for the new GUI
to be available under NT before using a better TPaveText editor.
