Bug 18429 ScrolledComposite with LayoutManager is VERY slow in iPAQ
Reported: 2002-05-31 09:05:35 | Status: resolved fixed

I've tried the examples for the ScrolledComposite from the javadoc on the iPAQ an it is very slow. After touching the slider it took 2 sec to move the slider to the new position and another 6 sec to scroll the content of the widget. I've tried the old examples (displaying 10 buttons) and the new one (two ScrolledComposite and one button to add buttons to these widgets). Then I modified the old examples (deleting the LayoutManager) and placed the buttons by myself (setLocation). This helps. Now I can move the slider while the content is repainted. Seems that the LayoutManager is too slow for the iPAQ. I'm using: iPAQ with pocketPC2002 swt-win32-2040.dll j9 You can find the examples in the old and the new javadoc of ScrolledComposite.
