Re: [dsdp-tm-dev] create rse connections programmatically.

hi david, i wonder why i always have to copy parts of the source code from scratchpad into my project. why not customize the scratchpad plugin project directly? do you think that it is easier? if so, where to download the source project? regard, wei.

Hi Wei,

Once you have a basic menu in place (standard jface context menu), you'll need to populate it.  For an example of how RSE populated the menu for both popup-menu extensions and the adapter-contributed actions, see SystemScratchPadView.fillContextMenu().

Re: [dsdp-tm-dev] create rse connections programmatically.







hi david,

i was so stupid and your last 2 mails were in fact not necessary at all. it works now. the treeview and the connections in it look good.

i've still got my last question here for you: in this view there's still no popup menu. how to build in all the standard rse popup menus for all the rse objects inside this tree?

regard,wei.

1) & 2) You should use SystemViewConnectionAdapter to display the label, icon and children of an IHost.  You don't need new code for that.

3) & 4) Your model would consist of the folders that contain existing RSE objects.  The objects contained in the folders (i.e. hosts) are existing RSE objects.  In the code I gave you, you'd replace IRemoteFile with whatever object your "connection folder" is (i.e.  IConnectionFolder).  You'd replace SystemViewFileAdapterFactory with something like SystemViewConnectionFolderAdapterFactory.

Re: [dsdp-tm-dev] create rse connections programmatically.









am i right here?

1)
SystemViewConnectionAdapter stays intact.

2) so i've been wrong to let my tree node model class extend SystemViewConnectionAdapter. it should implement IHost.  now i still need to let it implement
IAdaptable.

3) in your code below replace IRemoteFile with IHost and replace SystemViewRemoteFileAdapter with
SystemViewConnectionAdapter and replace SystemViewFileAdapterFactory with a class name i like i.e. HolySystemViewHostAdapterFactory.

4) in your code below replace
SystemViewFileAdapterFactory with HolySystemViewHostAdapterFactor.

regard,wei.

The shortcut for implementing ISystemViewElementAdapter is to extend AbstractSystemViewElementAdapter, which provides much of the generic implementation.


SystemViewConnectionAdapter is the correct adapter for IHost.  IHost is what you want.


When you provide your own adapter for your own model objects, you need to register it.  To do that, you need to provide the following:


1) You implementation of ISystemViewElementAdapter

2) Your model object needs to implement IAdaptable.  Typically you'd implement getAdapter() as follows:

     

 
public Object getAdapter(Class adapterType)
  {

             
return Platform.getAdapterManager().getAdapter(this, adapterType);        
  }    



3) You should provide an adapter factory class.  Here's an example of what we do for mapping IRemoteFile to SystemViewRemoteFileAdapter where:


IRemoteFile is the model object type

SystemViewRemoteFileAdapter is the ISystemViewElementAdapter


/**

*
This factory maps requests for an adapter object from a given
*
 element object. This is for the universal file system.
*/

public
class SystemViewFileAdapterFactory extends AbstractSystemRemoteAdapterFactory
{

     
private SystemViewRemoteFileAdapter fileAdapter = new SystemViewRemoteFileAdapter();
     
     
/**
       
* Called by our plugin's startup method to register our adaptable object types
       
* with the platform. We prefer to do it here to isolate/encapsulate all factory
       
* logic in this one place.
       
*/
     
public void registerWithManager(IAdapterManager manager)
      {

          manager.registerAdapters(
this, IRemoteFile.class);
      }

     
/**
       
* @see IAdapterFactory#getAdapter(java.lang.Object, java.lang.Class)
       
*/
     
public Object getAdapter(Object adaptableObject, Class adapterType)
      {

          Object adapter =
null;
         
if (adaptableObject instanceof IRemoteFile)
            adapter =
fileAdapter;

         
if ((adapter != null) && (adapterType == IPropertySource.class))
          {        

              ((ISystemViewElementAdapter)adapter).setPropertySourceInput(adaptableObject);

          }                              
             
return adapter;
      }        

}



4) Finally, you need to register the adapter factory  (for example, in your Activator at startup).  Here's how we do it for the files:


          IAdapterManager manager = Platform.getAdapterManager();

         
         
svfaf = new SystemViewFileAdapterFactory();        
         
svfaf.registerWithManager(manager);

Re: [dsdp-tm-dev] create rse connections programmatically.











of course thanks. i've got the last problem i think. you said "
Or you may choose to create an ISystemViewElementAdapter for your object.". yes i need to do this but there are 63 methods to implement for ISystemViewElementAdapter. is there any shortcut to create a connection like                
---------------------------------
         host = registry.createHost(

                                         
"SSH Only",        //System Type Name        //$NON-NLS-1$
                                         hostName,        
//Connection name
                                         hostName,        
//IP Address                
                                         
"Connection to Eclipse build site"); //description //$NON-NLS-1$
---------------------------------------
but IHost is not what we want, is it?
i tried to let my tree node model class extend SystemViewConnectionAdapter. but it does not seem to work and i never run into this bracket:
--------------------------------------

                   {

                             result.setPropertySourceInput(object);

                             result.setViewer(
_view);
                             
return result;
                     }

--------------------------------------
please let me know what you would do here! regard,wei.

With your own view, you probably already have a content provider and a label provider.  If you want to reuse the existing RSE model objects (i.e. connections, subsystems, filters, etc) there are adapters that can help out the provider.  The interface that these adapters implement is ISystemViewElementAdapter.  The interface has code to allow for getting the icon, label and children of a particular node, as well as other things, such as action contributions and properties.


The reason I point to the ScratchpadViewProvider, is that it's a good example of a content and label provider that makes use of the ISystemViewelementAdapter.  Here's code from the provider that allows you to get at a ISystemViewElementAdapter from a model object:


     
protected ISystemViewElementAdapter getAdapterFor(Object object)
     {

             
if (object instanceof IContextObject)
             {

                     object = ((IContextObject)object).getModelObject();

             }

         
if  (object instanceof IAdaptable)
         {

                 IAdaptable adapt = (IAdaptable) object;

                     ISystemViewElementAdapter result = (ISystemViewElementAdapter) adapt.getAdapter(ISystemViewElementAdapter.
class);
                     
if (result != null)
                     {

                             result.setPropertySourceInput(object);

                             result.setViewer(
_view);
                             
return result;
                     }

         }

             
return null;
     }


Once you have a way to get at the adapter, you can use it to implement the methods of the content provider and label provider as follows:


     
public boolean hasChildren(Object object)
     {

                                     
             ISystemViewElementAdapter adapter = getAdapterFor(object);

             
if (adapter != null)
             {

                     
if (object instanceof IContextObject)
                     {

                             
return adapter.hasChildren((IContextObject)object);
                     }

                     
else
                     {

                             
return adapter.hasChildren((IAdaptable)object);
                     }

             }

             ...

             
return false;
     }



     
public Object[] getChildren(Object object)
     {

             
return getElements(object);
     }

     
     
public Object[] getElements(Object object)
     {

             Object[] results =
null;

             Object element = object;

             
if (object instanceof IContextObject)
                 {

                         element = ((IContextObject)object).getModelObject();

                 }

             
if (element instanceof IAdaptable)
             {                                

                     ISystemViewElementAdapter adapter = getAdapterFor(element);

                     
if (adapter != null && adapter.hasChildren((IAdaptable)element))
                     {

                               
if (object instanceof IContextObject)
                           {

                                   results = adapter.getChildren(
new NullProgressMonitor(), (IContextObject)object);
                           }

                           
else
                           {

                                   results = adapter.getChildren(
new NullProgressMonitor(), (IAdaptable)object);
                           }

                     }

                     ...

             }

             
if (results == null)
             {

                     
return new Object[0];
             }


             
return results;
     }


     
public String getText(Object object)
     {

             ISystemViewElementAdapter adapter = getAdapterFor(object);

             
if (adapter != null)
             {

                     
return adapter.getText(object);
             }

             ...

             
return object.toString();
     }


     
public Image getImage(Object object)
     {

             Image image =
null;
             ISystemViewElementAdapter adapter = getAdapterFor(object);

             
if (adapter != null)
             {

                     ImageDescriptor descriptor = adapter.getImageDescriptor(object);

     
                     
                     
if (descriptor != null)
                     {

                             Object iobj =
imageTable.get(descriptor);
                             
if (iobj == null)
                             {

                                     image = descriptor.createImage();

                                     
imageTable.put(descriptor, image);
                             }

                             
else
                             {

                                     image = (Image) iobj;

                             }

                     }

                     
return image;
             }

             ...

             
return null;
     }



Once you have the content provider setup properly, then you just need to make sure you populate the initial nodes of the tree as you wish (wiht you connection folder objects).   You might either hardcode the provider to deal with your objects:


             if (object instanceof MyConnectionFolder)

             {

                     ...

             }


Or you may choose to create an ISystemViewElementAdapter for your object.


Does this help?

Hi Wei,


For what you want to do, the current Remote Systems view will not work.  You could write your own view and reuse much of the RSE functionality.  In particular, you could have the label and content provider make use of the SystemView adapters for the RSE model objects which you use.


For a simple example, you could take a look at:
SystemScratchpadViewProvider.   This is what the scratchpad view does to display the same sorts of things that the Remote Systems view displays.  In this case, you'd need to provide a new model object for these "connection folders" as well as it's corresponding adapter.

RE: [dsdp-tm-dev] create rse connections programmatically.















Hello Wei,

I'm afraid that what you want to do is not possible
with our official API. It may be possible by deriving
from RSE SystemView, and implementing a custom
SystemViewContentProvider.

I'm copying the dsdp-tm-dev list. Please CC the list
for all such kinds of requests, since there might be
others who know the answer better than any individual.

DaveM, can you help?
