Hi Danny, it would be multi line text and I don't know if it will be center aligned. Maybe some parts will be. I didn't really get the technique you described. Can you please try and describe it again? Or is it possible that you share the code that you have? I can even compensate it somehow if it gets used.
Another idea is to sort of hardcode the y values, as textfield will always be in the same place and always the same font size and font face (hopefuly). X value of mouse press is simple and I would just see where in which row of the grid the mouse press occured and use that. Say I know each row is 10 px high, and the press occurs on x=56, y=23. I would then start drawing the rectangle from the point 56,20. Alen > Hi list, any tips on how to create a text highlighter? The
perfect solution will be that I use the text cursor inside the textfield. Now, I was thinking of using drawing API on the invisible mc below the textfiled and when I would click in the textfield I would start drawing a rectangle on that mc. But, the problem is that with the text cursor you can click anywhere between the lines and it will select the closest line. So I can't get the exact y coordinate where to start drawing the rectangle. Also, I don't think I can use background-color css property as it's not supported according to Flash documentation.
It's a very tricky problem - not only are there the problems you mention, but also if they're selecting multiple lines you need to draw three rectangles rather than one - the shorter top and bottom part-lines and the full lines in the middle. I've done it in the past (although in the end I didn't use it) by creating a function that homes in on the exact coordinates of the insertion point by adding text into a hidden field and using textWidth / textHeight (the tricky part is finding the start of the current line, the rest is fairly easy, although I'm not sure how you'd do centre-aligned text). It sounds hideous, but actually Flash is pretty fast at that kind of thing and it worked fine in real-time for reasonably short text. If your text is single-line, obviously it's much easier.
