Hi,
they are available through the entire lifetime of the application (the tabs are stored per layout in a QList<std::shared_ptr>. I have one Q_INVOKABLE method that returns a pointer to the tab.
Q_INVOKABLE ViewManagerTabQMLInterface* getTab(int index);
//--------------------------------------------------------------------------------------
/// Returns the tab model from the given index.
//--------------------------------------------------------------------------------------
ViewManagerTabQMLInterface* ViewManagerQMLInterface::getTab(int index)
{
if(index >= 0 && index < (int)_tabsList.size())
{
return _tabsList[index].get();
}
return NULL;
}
Q_INVOKABLE ViewManagerTabQMLInterface* getTab(int index);
//--------------------------------------------------------------------------------------
/// Returns the tab model from the given index.
//--------------------------------------------------------------------------------------
ViewManagerTabQMLInterface* ViewManagerQMLInterface::getTab(int index)
{
if(index >= 0 && index < (int)_tabsList.size())
{
return _tabsList[index].get();
}
return NULL;
}

I see that at one point the destructor of the ViewManagerTabQMLInterface is called after a QDeleteDefferedEvent (just reading from the call stack).
