Wt

Hello, I'm trying to convert a big application to wt4,

I'm getting some errors that I will post here, first one is with toolbar widgets, I'm using the "widget()" method of the WToolbar to get a non owning pointer of the items:

auto lang_toolbar = make_unique<WToolBar>();
lang_toolbar->addWidget(make_unique<WComboBox>(), AlignmentFlag::Right);
WComboBox* lang_select = (WComboBox*)lang_toolbar->widget(lang_toolbar->count()-1);

But each call to lang_toolbar->widget(lang_toolbar->count()-1); fails, any idea ?

Kind regards
J.
