odd double widgets

[jhearon]

I'm answering my own post.
I finally figured out the answer to this problem which is in the constructor for the model.cpp class. The SoQtExaminerViewer portion below uses a protected constructor, and delaying a superclass viewer from building it's decorations is done by passing build==FALSE as the last argument of the protected constructor. You then have to explicitly trigger the building in your own constructor.

model.cpp

Model::Model( QWidget *parent, 
              const char * name, 
              const SbBool embed)
  : SoQtExaminerViewer( parent, 
                        name, 
                        embed, 
                        SoQtFullViewer::BUILD_ALL, 
                        SoQtViewer::BROWSER, FALSE)
 
  // Explicitly triggers the construction of viewer decorations.
    QWidget * widget = this->buildWidget(this->getParentWidget());
    this->setBaseWidget(widget);

Model::Model( QWidget *parent, 
              const char * name, 
              const SbBool embed)
  : SoQtExaminerViewer( parent, 
                        name, 
                        embed, 
                        SoQtFullViewer::BUILD_ALL, 
                        SoQtViewer::BROWSER, FALSE)

  // Explicitly triggers the construction of viewer decorations.
    QWidget * widget = this->buildWidget(this->getParentWidget());
    this->setBaseWidget(widget);

To copy to clipboard, switch view to plain text mode 

...therefore with "...SoQtViewer::BROWSER, TRUE)", above, the viewer decorations were getting built twice. Yikes.
