Hi, I have a page with scrollable text area. By default, its vertical scrollbar is off, and WebKit turns it on only when I insert more lines than the area can show.
The number of lines in the area is 4. When I insert 5th line, WebKit creates a vertical scrollbar and call its updateThumbProportions() method. In this method I see the following values: m_totalSize = 75 (5 lines) m_visibleSize = 60 (4 lines) m_lineStep = 40 m_pageStep = 20 m_pixelStep = 1.0 Each time I press scrollbar buttons, it should be scrolled by 15, but I can't see how I can get/calculate 15 from the values above to set scrollbar's unit increment. Thanks, Artem _______________________________________________ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo/webkit-dev
