Hi All
I needed to know the Pros and Cons about
1)Using a tree view inside the editor
for this my understanding is I could use the
"org.eclipse.gef.ui.parts.TreeViewer"
My Question is how different is it from the
"org.eclipse.jface.viewers.TreeViewer"
2)Using the Editor inside a treeview
for this I could see this link and found out that it is not possible in
present eclipse 3.1
http://dev.eclipse.org/mhonarc/lists/platform-swt-dev/msg044 88.html
Also please suggest for the folowing:-
In our project there is a requiremnet to show a tree view and a multipage
editor with two tabs one which has a source view "an xml file" and a
design view which is again a structured tree view where I could drag and
drop elements from the palette.(I think of using GEF for this)
How difficult is this for this I need to divide the Editor into tow parts
one with the tree view and another part with multitab editor and a palette.
Thanks & regards

I think you are confusing Viewer and View. He just wants a tree control
inside his editor.
Or maybe I'm confused...

Hi All
Okay I will state my query once more,
My specefic requiremnet is in Multipage editor on one tab I need to show a
tree editor where i can show a tree which I could manipulate to listen to
drag and drop ,also I need to show a palette for this page.
For the above case I was able to get a tree with out using treeeditor
following is the code but I cannot figure out how to create a palette for
a multipage editor I need some hints on this
************************************************************ ******************
void createPage1() {
Composite composite = new Composite(getContainer(), SWT.NONE);
//GridLayout layout = new GridLayout();
composite.setLayout(new FillLayout());
final Tree tree = new Tree(composite, SWT.BORDER);
File[] roots = File.listRoots();
for (int i = 0; i < roots.length; i++) {
TreeItem root = new TreeItem(tree, 0);
root.setText(roots[i].toString());
root.setData(roots[i]);
new TreeItem(root, 0);
}
tree.addListener(SWT.Expand, new Listener() {
public void handleEvent(final Event event) {
final TreeItem root = (TreeItem) event.item;
TreeItem[] items = root.getItems();
for (int i = 0; i < items.length; i++) {
if (items[i].getData() != null)
return;
items[i].dispose();
}
File file = (File) root.getData();
File[] files = file.listFiles();
if (files == null)
return;
for (int i = 0; i < files.length; i++) {
TreeItem item = new TreeItem(root, 0);
item.setText(files[i].getName());
item.setData(files[i]);
if (files[i].isDirectory()) {
new TreeItem(item, 0);
}
}
}
});
int index = addPage(composite);
setPageText(index, "Design");
}
************************************************************ ******************
On the second page I need to show an XML structure which would show a XML
file. Which is not a problem as I can use the XML editor for this.
Randy I need some hints so as to how can I make a palette for Multipage
Editor
Thanks
Sai

okay I was able to create a paleete for the multipage editor
I created a simple editor "SimpleEditor extends GraphicalEditorWithPalette
"
and did
addPage(simpleeditor, getEditorInput()); inside one page of the
multieditor
Now I am Grappling with bringing in a tree inside this simpleeditor how
could I achieve this
simpleeditor is a GraphicalViewer so is it possible to put treeviewer
inside the Graphicalviewer
Thanks
