http://www.nabble.com/file/p15950710/Pane-InvalidMarkup-PerformanceImprovement.patch Pane-InvalidMarkup-PerformanceImprovement.patch I had noticed some time ago that a few invalid "font-family" and such errors were issued in Firefox's Error Console but I though it had to do with some theming issue or such. I tried to isolate the issue and the results were not what I had in mind.
Reproduces: Always Steps to reproduce: 1. Open Firefox's Error Console (in Tools menu); 2. Open "Table 1" of Demo Browser's examples; 3. Slowly scroll to the last line (using the scroll arrows); 4. Slowly scroll up; 5. Repeat 3 and 4 a few times; 6. Quickly scroll down (dragging the scrollbar); 7. Quickly scroll up; 8. Repeat 6 and 7 a few times. Expected results: Scroll happens. No errors are shown. Actual results: In steps 3 to 5, CSS errors are shown in Error Console every time the last table line is shown; In steps 6 to 8, when scroll is very fast similar CSS errors are shown. Scroll behavior feel has small pauses. Additional notes: This was hunted down to pane code which inserted invalid CSS code (unescaped apostrophes). Additional inspection made realize that "font-size" and "font-family" were redundant as .qooxdoo-* CSS classes already take care of default look, so I removed (commented) these lines to further improve performance. The small pauses experienced in Firefox were probably due to the invalid markup inserted and seem to be fixed. :-) http://www.nabble.com/file/p15950710/Abstract-UserSelect-CoherencyImproved.patch Abstract-UserSelect-CoherencyImproved.patch For table, text selection seems to be fixed in Opera 9.26 (in Opera 9.5 the changes aren't effective though). The change may also help further improvements in Widget class, where is stated that «Opera currently has no support to prohibit user selection». Coherency was also somehow improved here (indenting, CSS code declaration). http://www.nabble.com/file/p15950710/Client-BoxSizing-RemoveCSSError.patch Client-BoxSizing-RemoveCSSError.patch Few "box-sizing" CSS errors were removed to further minimize error output. Several 'box-sizing' are still shown (qooxdoo log window, demobrowser CSS, etc.) but they can be probably be removed also by using a similar approach. With these patches applied, most (all?) qooxdoo-related CSS errors seem to be removed. Also ran few Demo Browser layout tests and such to ensure that core behavior was left untouched. Used Firefox 2.0.0.12 (also 3.0b5pre), Internet Explorer 7, Safari 3.0.4 beta, Opera 9.26 (also 9.50 beta).
