Bug 539724 - ContainerCheckedTreeViewer performance is bad The performance of ContainerCheckedTreeViewer is very bad, when updating the checked state of many of the items at the same time. If a single checkbox is set checked or unchecked, all the parents and all the children of that checkbox are updated. Therefore when setting the checked state of all checkboxes (due to restoring the state of the viewer after some filtering or similar), many of the parents and many of the children are updated multiple times. This change improves performance in multiple ways: * use setRedraw() to disable repainting while multiple items are updated in loops * shorten the traversal over parents and children by detecting when there will be no changes anymore to the state of the further parents or children * reimplement the update loop for setting the state of multiple items, and calculate all the affected children and parents which need to be updated once, such that their windows controls are updated only once overall, and not once per modified item. Overall, this makes the target platform editor content tab way more responsive.

Thanks for your interest in this project.
Platform UI provides the basic building blocks for user interfaces built with Eclipse.
Some of these form the Eclipse Rich Client Platform (RCP) and can be used for arbitrary rich client applications, while others are specific to the Eclipse IDE. The Platform UI codebase is built on top of the Eclipse Standard Widget Toolkit (SWT), which is developed as an independent project.
