Wt

Since class ToggleButton inherits class WText.
in WText.c:

WText::WText(...)
{
  WT_DEBUG(setObjectName("WText"));
  ...
}

the id in DOM will have a "WText_" prefix
but, the Toggle button's signals exposed with "pure" id without any prefix.
so, the button dosnt work, and will log a "[Error]... signal not exposed".

proposal in WTreeView.C:

class ToggleButton : public Wt::WText
{
  ToggleButton() 
    : WText(...),
      ...
  {
    //prevent prefix "WText" of DOM id
    WT_DEBUG(setObjectName(""));


    ...
    ...
  }
