Hi @ all!
Anyone knows a nice tutorial how to create a multi page editor, which
edits an xml File like the plugin.xml?
And which eclipse plugin defines the functionality for editing the
plugin.xml?
Thanks in advance
Johannes

Hi,
NB: it's an example (not for doing a XML multi page editor, but a multi
page editor) i don't know if it's a good use but it works( excuse me I'm
a little busy today if you have some question, and if there are mistakes
you can correct me (I'm a newbee).
to create a multi page editor you need :
- in the plugin.xml :
<extension point="org.eclipse.ui.editors">
<editor
class="org.example.XMLEditor"
default="true"
icon="penguin.gif"
id="org.example.XMLEditor"
matchingStrategy="org.example.XMLEditorMatchingStrategy"
name="XMLEditor">
</editor>
</extension>
You can add of course the extension of the files, the icon...
- The class XMLEditor
public class XMLEditor extends FormEditor {
public static final String ID_EDITOR = "org.example.XMLEditor";
//$NON-NLS-1$
protected FormToolkit createToolkit(Display display) {
// Create a toolkit that shares colors between editors.
return new
FormToolkit(ConfigurationPlugin.getDefault().getFormColors(d isplay));
}
protected void addPages() {
try{ // note book like in the editor
addPage(new FreeFormPage(this));
addPage(new FreeFormPage2(this));
addPage(new FormPage3(this));
addPage(new FormPage4(this));
addPage(new FormPage5(this));
}catch(PartInitException e){
}
}
public void doSave(IProgressMonitor monitor) {
// TODO Auto-generated method stub
}
public void doSaveAs() {
// TODO Auto-generated method stub
}
public boolean isSaveAsAllowed() {
// TODO Auto-generated method stub
return false;
}
public void init(IEditorSite site, IEditorInput input) throws
PartInitException {
this.setPartName(input.getName());
this.setTitleImage(ConfigurationPlugin.getImageDescriptor("an
image").createImage());
this.setTitleToolTip(input.getName());
super.init(site, input);
}
}
- a class XMLEditorInput whiwh define your instance of an editor
public class XMLEditorInput implements IEditorInput {
private String name = null;
public XMLEditorInput() {
super();
// TODO Auto-generated constructor stub
}
public XMLEditorInput(String name) {
super();
this.name=name;
// TODO Auto-generated constructor stub
}
public boolean exists() {
// TODO Auto-generated method stub
return true;
}
public ImageDescriptor getImageDescriptor() {
// TODO Auto-generated method stub
return null;
}
public String getName() {
// TODO Auto-generated method stub
return name;
}
public IPersistableElement getPersistable() {
// TODO Auto-generated method stub
return null;
}
public String getToolTipText() {
// TODO Auto-generated method stub
return name;
}
public Object getAdapter(Class adapter) {
// TODO Auto-generated method stub
return null;
}
public boolean equals(Object obj) {
if (obj == null) return false;
if (! (obj instanceof XMLEditorInput)) return false;
XMLEditorInput other = (XMLEditorInput)obj;
if (!(other.name.equals(this.name)))return false;
return true;
}
public int hashCode() {
// TODO Auto-generated method stub
return name.hashCode();
}
}
- the matching strategy class
public class XMLEditorMatchingStrategy implements IEditorMatchingStrategy {
public XMLEditorMatchingStrategy() {
super();
// TODO Auto-generated constructor stub
}
public boolean matches(IEditorReference editorRef, IEditorInput input) {
try { // check you have not the same editoralready open, useful for
opening a new one
return editorRef.getEditorInput().equals(input);
} catch (PartInitException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return false;
}
}
}
- the pages you add
public class FreeFormPage extends FormPage {...
Here you can do your "editor" for an XML
I you use a tree view you have done by yourself
in the double click action for example do this :
doubleClickAction = new Action() {
public void run() {
ISelection sel = viewer.getSelection();
if (sel instanceof IStructuredSelection) {
IStructuredSelection selection = (StructuredSelection) sel;
Object obj = selection.getFirstElement();
IWorkbenchPage page = ConfigurationPlugin.getDefault()
.getWorkbench().getActiveWorkbenchWindow()
.getActivePage();// it's the plugin.java of my apps
File temp = (File) obj;
try {
IEditorInput input = new XMLEditorInput(temp.getName());
page.openEditor(input,
"The id of your editor");
} catch (PartInitException e) {
System.out.println(e);
}
}
}
};
THE END :D
