Re: [ve-dev] Facing problems in working with the custom widgets

[Rich Kulp <richkulp@xxxxxxxxxx>]

Hi,

To the VE, myCustomWidget.addElement(...)
isn't a property on myCustomWidget, so it ignores those statements when
it parses the code. So it won't add anything. A property is of the form
getSomething()/setSomething(Something). 

But, we also don't parse Vectors, so
even if you had done myCustomWidget.getElements().addElement(...) we would
ignore it.

Sorry about this,

Rich

Hi Rich,
 
Thanks for the reply.
 
I have extracted the ComponentGraphicalEditPart from the
ScrollingGraphicalViewer of the current EditDomain for my custom widget.
 
The following is the code that I am trying to use 
 
Note: variable componentGraphicalEditPart editpart for
MyCustomWidget.
 
//Code Starts here
 
JavaObjectInstance javaObjectInstance = (JavaObjectInstance)
componentGraphicalEditPart.getModel();
 
IBeanProxy customWidgetBeanproxy = BeanProxyUtilities.getBeanProxy((JavaObjectInstance)
javaObjectInstance);
 
try {
 
IMethodProxy methodProxy = customWidgetBeanproxy.getTypeProxy().getMethodProxy("getElements");
 
IBeanProxy elementsBeanProxy = methodProxy.invoke(customWidgetBeanproxy);
 
CollectionBeanProxyWrapper elementsWrapper = new CollectionBeanProxyWrapper(elementsBeanProxy);
 
IteratorBeanProxyWrapper elementsItr = elementsWrapper.iterator();
 
IStringBeanProxy elementProxy;
 
Vector elements = new Vector(elementsWrapper.size());
 
while (elementsItr.hasNext()) 
{
 
elementProxy = (IStringBeanProxy) elementsItr.next();
 
elements.add(elementProxy.stringValue());
}
} 
catch (ThrowableProxy e) 
{
e.printStackTrace();
}
 
Thanks,
Shobana.R

Hi, 

How are you invoking the addElement() exactly through the beanproxy?

Are there any errors in the .log file? 

When you invoke it the second time, does add the first one again so that
there are two? 

Thanks, 
Rich

Subject	[ve-dev] Facing problems in working with the custom widgets

Hi All, 
  
I am facing some problems with the implementation of custom widgets for
my application. I have a custom widget that has a property of type Vector
(Holding a set of values). I use the CustomWidget as follows, 
  
public void mycustomWidget() 
{ 
    if(mycustomwidget1==null) 
    { 
       myCustomwidget1 = new MyCustomWidget(); 
       ………. 
       myCustomwidget1.addElement("aaa"); 
       myCustomwidget1.addElement("bbb"); 
    } 
    return myCustomwidget1; 
} 
  
The addElement() method in the MyCustomWidget class is as follows 
  
public void addElement(String element) 
{ 
   if(!(element.equals(""))) 
   { 
     elements.add(element); 
   } 
} 
  
public Vector getElements() 
{ 
return elements; 
} 
  
For one of my wizard, I have to extract the editpart for the custom widget
and using bean proxy get the elements added to that custom widget. 
But when I invoke the addElement ()’ method through the beanproxy, I get
only the first element added. Only the first call to addElement is recognized.
Can any body please help me resolve this? I need to get all the elements
added. 
  
Please help me in this regard. 
Thanks in advance. 
  
Regards, 
Shobana.R
