RollOver effect and Custom Property Editors

[vampie]

are there anyway to set rollover effect and adding new custom based events
to list?

I have been using Echostudio to test, and i could not add My Custom Class
Property Editors to the Property Sheet. Is it possible on GWT and your designer

Echostudio? Do you mean this http://www.nextapp.com/platform/echo1/echostudio/ ? It is not related with GWT or GWT Designer.

What kind of property editors do you want? Can you give examples? We have support for custom property editors in our Swing and SWT Designer's, so we can add something like with for GWT (most probably same as for SWT because Eclipse is SWT based, so SWT is native for us). But I would like to see what you want first to decide if we will want something valuable for you.

No please look echo2.. it is related with ajax... Echo1 is old.

For example i need to have jbuilder style QueryDataset. I have written
some library for fetching data and JBuilder like dbSwing componets ( data
aware components )

To be more specific, I need to have property editor that is inherited from
JPanel... I have PBDBConnection class derived from Connection. in this editor i need JDBC URL Text Edit, JDBC jar class path textedit.. and so on..

Is it possible to write such property editors and make them shown in your property sheet ?

Thx in advance...

In general yes, this is possible. But I don't understand why you speak about JBuilder, JPanel and Swing at all. I can see only two GUI toolkits: SWT (because Eclipse is SWT based) and GWT (because we support GWT). So, why Swing?

Here is old topic about custom property editors and SWT in our forum: http://www.instantiations.com/forum/viewtopic.php?t=756&highlight=custom+property

Keep in mind that GWT is different from just using JavaScript for adding some effect. In GWT you can write special widgets that support needed functionality. For example, see below simple subclass of Hyperlink that has rollover effect for image. In general you can do anything in onBrowserEvent(), for example change style (using addStyleName() or setStyleName()) and use CSS to change look of your widget.

Code: Select all

/**
* Simple {@link Hyperlink} with rollover effect for image.
*
* @author scheglov_ke
*/
public class RolloverImageHyperlink extends Hyperlink {
   private final Image m_image = new Image();
   private String m_normalURL;
   private String m_hotURL;
   ////////////////////////////////////////////////////////////////////////////
   //
   // Constructor
   //
   ////////////////////////////////////////////////////////////////////////////
   public RolloverImageHyperlink() {
      DOM.insertChild(getElement(), m_image.getElement(), 0);
      m_image.unsinkEvents(Event.ONCLICK | Event.MOUSEEVENTS);
      sinkEvents(Event.ONCLICK | Event.MOUSEEVENTS);
   }
   ////////////////////////////////////////////////////////////////////////////
   //
   // Images
   //
   ////////////////////////////////////////////////////////////////////////////
   public void setNormalURL(String normalURL) {
      m_normalURL = normalURL;
      m_image.setUrl(m_normalURL);
   }
   public void setHotURL(String hotURL) {
      m_hotURL = hotURL;
   }
   ////////////////////////////////////////////////////////////////////////////
   //
   // Events
   //
   ////////////////////////////////////////////////////////////////////////////
   public void onBrowserEvent(Event event) {
      super.onBrowserEvent(event);
      switch (DOM.eventGetType(event)) {
         case Event.ONMOUSEOVER : {
            m_image.setUrl(m_hotURL);
            break;
         }
         case Event.ONMOUSEOUT : {
            m_image.setUrl(m_normalURL);
            break;
         }
      }
   }
}

And test case for it, don't forget to add your own images.

Code: Select all

public class ImageViewer implements EntryPoint {
   final RootPanel rootPanel = RootPanel.get();
   public void onModuleLoad() {
      {
         final RolloverImageHyperlink rolloverImageHyperlink = new RolloverImageHyperlink();
         rootPanel.add(rolloverImageHyperlink, 153, 188);
         rolloverImageHyperlink.setText("New hyperlink");
         rolloverImageHyperlink.setNormalURL("radio_button.gif");
         rolloverImageHyperlink.setHotURL("check_box.gif");
      }
   }
}

I just give example about what kind of Property Editors I want. I do not code in swing right now. I am trying to use gwt Like swingset.sf.net DB widgets.
I want to implement them in GWT. I am comparing GWT and Echo2 ajax
frameworks...

Thx for the help so far.

Are you saying that you want to actually implement custom property editors in GWT itself?

[vampie]

No I want to implement new db aware beans like swingset.sf.net...

[Eric Clayberg]

No I want to implement new db aware beans like swingset.sf.net...

What toolkit do you want to use in order to create your custom property editors?

[vampie]

Sure i want to use GWT but not sure if gwt support custom property editors same like JBuilder or Netbeans. If not i will try to implement. Does Gwt designer's property sheet have support for Custom Editors ?
