Custom Composite not showing in "Choose Composite"

[NickAltix]

Hello, I'm wrapping SWT widgets (Text, Combo, Table) in Composites to add functionnalities to each widget. I have created an abstract class called IControlModel that contains code used by each new control. Im extending this new class for each new widget i want to create. I cannot choose the new, for example, "TextModel" class from the "Choose Composite" dialog. However if i insert a Text widget and change its type to TextModel i can see it in the design window.

I suppose the software doesnt recognize my new Composite since its inheriting from another abstract class.

Here is the classes definition to help you understand my problem.

Code: Select all

public abstract class IControlModel extends Composite implements Observer {

   public IControlModel(Composite parent, int style) {
      super(parent, style);
   }
   
   //Some abstract methods
   //Some concrete methods
   
}

public class TextModel extends IControlModel  {

   private Text txtModel;
   
   public TextModel(Composite parent, int style ) {
      super(parent, style, objName);
      setLayout(new FillLayout());
      {
         txtModel = new Text(this, SWT.BORDER);
      }
   }
   //added functionnalities
}


Thanks

No. Designer would not care what the inheritance hierarchy is.

When I tried your example code, it worked just fine. I was able to choose the TextModel class and drop an instance in the design view.

I would suggest trying it with the latest v2.0.1 build to see if it makes any difference. If not, I will need you to send the complete source for both classes to us at support@swt-designer.com.
