Wt

hi, Wt group:

Continuing with the #788, I found another problem at row838:

WWidget *hc = headerWidget(column)

row838 invokes headerWidget(int column, bool contentsOnly) at row1026, the real problem is bool contentsOnly at row1042-1045

  if (result && contentsOnly)
    return result->find("contents");
  else
    return result;

I found result->find("contents") returns a empty WContainerWidget(*w) at the WAbstractItemView.C row937-938 as below:

  WContainerWidget *w = new WContainerWidget();
  w->setObjectName("contents");

All these lead to a situation:

When dynamically control(such as by Hide or Show button) the visibilities of some columns which have been rendered, the columns would hide or show corrently and header could change width correctly, but with no header data(header name).

in my test :

WWidget *hc = headerWidget(column, false)

is ok.
