Hi,
I am trying to add a widget to the toolbox by emit addToolbox(tr("Simplification"), m_toolbar), but nothing shows up
However, I found that if I replace the name 'Simplification' with the name of whatever widget already exists in the toolbox, I got what I want. For example, if I name my widget as 'Smoother' (a widget with this name already exists in the toolbox), two widgets with the name 'Smoother' show up.
