Sandro Martini commented on PIVOT-454: -------------------------------------- Some related discussion here: http://apache-pivot-users.399431.n3.nabble.com/Viewport-scrolling-performance-td3219817.html > Provide an alternate scroll pane optimization > --------------------------------------------- > > Key: PIVOT-454 > URL: https://issues.apache.org/jira/browse/PIVOT-454 > Project: Pivot > Issue Type: New Feature > Components: wtk > Reporter: Greg Brown > Fix For: 2.1 > > > This optimization would perform double-buffering in the viewport component > (or skin) rather than copying the contents of the video buffer. The buffer > would be restricted to the size of the viewport rather than the view. > The component can rebuild the buffer every time it is called to repaint (or > possibly limit to updating the repaint region?). When the viewport top left > or bottom right changes, the component can paint the unaffected area into the > new buffer, then only repaint the affected area. > This optimization will allow content to be painted on top of a scroll pane, > which the current optimization does not support (e.g. non-modal dialogs and > watermark decorators do not work with the existing optimization). -- This message is automatically generated by JIRA.
