| [bpel-dev] adding source view - patch #1 |
|
Hello, Please find attached the first patch re source view
development. A source view itself is added, it reacts on the
designer area (=BPELEditor) selection changes. I.e. if you select an element in
the design view and switch to the source view then you see the corresponding
piece of text selected. I used ideas and code from the XML editor. What is in the patch. 1. BPELMultipageEditorPart (extends org.eclipse.ui.part.MultiPageEditorPart)
is taken as the base class for BPEL multipage editor. This class will hold all the “core” functionality
of the editor UI: handling events, etc. Design and text views (BPELEditor and org.eclipse.wst.sse.ui.StructuredTextEditor)
will be just views. I haven’t moved any core functionality from
BPELEditor to this class yet. 2. org.eclipse.wst.sse.ui is added to the org.eclipse.bpel.ui
dependencies. This is needed to make possible import of org.eclipse.wst.sse.ui.StructuredTextEditor. 3. Editor class BPELEditor is changed to
BPELMultipageEditorPart in the org.eclipse.ui.editors extension point of org.eclipse.bpel.ui. Feel free to express your opinion J Thanks, Vitaly. |
