In MFC CRicheditctrl, how to get the reactangle occupied by the character

Question

In windows OS, in MFC CRichEditctrl, PosFromChar() gives top left position of a character, how to get the height of the character or a rectangle occupied by that character?

Answer 1

So - you have a top-left already. Getting a top-left for the next character will get you your top-right.

Now for the bottom. You can use CRichEditCtrl::LineFromChar to get your line index. Then use CRichEditCtrl::LineIndex to get the character on the next line. That character's top is your bottom.

If there is only one line in your control, you can call cricheditctrl::CharFromPos() repeatedly while incrementing vertical position until it will return the next character. If this is the last char, you can do that for the previous one. If there is only one char in a control - you can temporary add another one, get your coordinates and remove it.
