in the Eclipse Version of Oxygen you offer a Tree with the structure of the XML content in the active IEditorPart.
Above this Tree(-Viewer) you offer a text control to filter the Tree(-Viewer) which is different to the common Eclipse Filter and therefore also different to our filter-text-controls.
The Eclipse Framework already offers the org.eclipse.ui.dialogs.FilteredTree Composite, which is for instance also used in the Preferences.
Maybe it is a bit fussy, but could you consider to also stick to the common UI/Icons of Eclipse concerning this filter-text-control?
I think it is better to have equal icons for equal actions in order to have a corporate identity and no confused customers.
If it does only concern the Preferences of Eclipse I wouldn´t have mentioned that, but we also use this filter-text-control really often.
Here you can find the icon which is used in the Eclipse Preferences:
Thanks in advance.
