Wt

I love layouts, and I love WTableView and how I can get 100's of 1000's of rows of data to be able to 'scroll'. However, I struggle trying to get layouts to behave and I struggle trying to get WTableView to behave within those layouts. I was told that the "layouts" need to exist all the way down to the root() container. I do that... yet I struggle.

So, in this code, this is what I get:

475 #ifndef NEVER·
476 ·
477   //·
478   // this DOES NOT allow these WTableView to honor the layout and scroll as expected·
479   //·
480   auto u_tabWidget = std::make_unique<Wt::WTabWidget>();·
481   u_tabWidget-> addTab( std::move( std::make_unique< WarehouseCustomerWidget>  ( session() ) ), "customers" );·
482   u_tabWidget-> addTab( std::move( std::make_unique< WarehouseInventoryWidget> ( session() ) ), "inventory" );·
483   u_tabWidget-> addTab( std::move( std::make_unique< WarehouseCalendarWidget>  ( session() ) ), "calendar"  );·
484   u_tabWidget-> addTab( std::move( std::make_unique< WarehouseUsersWidget>     ( session() ) ), "users"     );·
485   u_tabWidget-> addTab( std::move( std::make_unique< WarehouseAdminWidget>     ( session() ) ), "admin"     );·
486   lw()-> addWidget( std::move( u_tabWidget ), 1 );·
487 ·
488 #else·
489 ·
490   //·
491   // this DOES allow the WTableView to 'fit' and 'scroll' as expected·
492   //·
493   lw()-> addWidget( std::move( std::make_unique< WarehouseCustomerWidget > ( session() ) ), 1 );·
494 ·
495 #endif·
496 ·

So, I know it has something to do with the tab-widget stacked-widget and that probably layouts need to be applied to that as well... but I'm unclear as to how?
