Hi guys/gals, I''ve got a problem with my textbox. Basically, textbox is a static control with ability to edit text, right? So, the problem comes when a user clicks on the textbox and a caret appears - the problem is how to determine correct caret position using given text, font characters size (in units), and additional troubles like newlines in text, etc. So, how would I determine a position of a caret based on mouse X/Y position, font xSize and ySize, and textbox sizes xTextBox and yTextBox, and a text "Hello there\n How are you?".... Please help. Thanks. " Do we need us? "

It''s not that difficult, it''s only a lot of little work.

Basically, have a text wrapping function that produces the actual lines of text.

Either calculate for every line or assume one single line height.

Do all the little things and sum them up:

Y = yTextBox + all_visible_lines_from_top_of_textbox * lineheight;
x = xTextBox + letter_1_width + letter_2_width + ...

That''s all there is to it.
