Boris, Thank you for your detailed answer. I see what you said now. I have this example: <html> <p>We collect personal information on this site. To learn more about how we use your personal information, see our <a href="http:// us.ard.com/">Privacy Policy</a>.</p> </html> My browser window is small (400 pixels in width , so it breaks in 'how to use'). But i only see 2 nsTextFrame get created, and 1 nsInlineFrame get created before and after reflow. And as you said all values of mContentLength of both nsTextFrame are 0 before reflow. But after reflow, the mContentLength of the first nsTextFrame is 35. So my questions are: 1. I don't see a new nsTextFrame get created even when the text got broken into 2 lines. Or I mis-understand what you meant? 2. is there a better way to get the length of the text before reflow? Thank you. _______________________________________________ dev-tech-layout mailing list [email protected] https://lists.mozilla.org/listinfo/dev-tech-layout
