Description Jacques LESCOT CLA 2010-05-27 10:27:15 EDT 
These actions are particularly useful when the tree displays many elements using a deep hierarchy : it could be a good way to reset the tree contents to its initial state (all elements are collapsed) or to quickly expand all elements to explore the whole contents of the tree.

I propose to define a new style in the EmfMasterDetailBlock class that will be used to configure the buttons so that the user can have these buttons visible in the TreeViewer's toolbar.

The collapse.gif and expand.gif images could be retrieved from existing Eclipse projects or directly from the following URLs:

Support Expand/Collapse buttons - v2

New patch with minor improvements : use setRedraw(false) and setRedraw(true) to avoid unnecessary UI updates while the tree is being expanded/collapsed.

Benjamin, you simply forget to add the two icons ("collapse.gif" and "expand.gif") in the "icons/obj16" folder.
Comment 7 Benjamin Cabé CLA 2010-06-17 04:25:26 EDT 
Oops, done.
