I wanted an edit that shows format characters (‘TAB’ and ‘CRLF’). I tried a
little with an CEdit but it never worked.
The I found CRTFCtrl::GetCharPos() which will give you the coordinates of a
given character in the control. With this function I was able to determin the
position of the format characters I wanted to be shown.
So all I do is everytime the content of the control alters I redraw every
visible format character.
The approach is very generic and can be used for other effects.
BUGs: If you drag and drop text with format characters, the selection remains
(-> any help with this problem is welcome!)
