[Paraview-developers] Hiding programmatically a Toolbar in a pvCustomApplication

[Louka Jacques--Chevallier]

Hello again, 
We're trying (yet failing) to hide a Toolbar programmatically in a pvCustomApplication. 
The toolbar has been installed using : pqParaViewMenuBuilders::buildToolbars(*this);

What actually works : 
-Accessing the toolbar, clearing its content
-Showing the toolbar

What doesn't work : 
-Hiding the toolbar...

What has been tried : 
-this->findChild<QToolBar *>("MainControlsToolbar")->hide();
-this->findChild<QToolBar *>("MainControlsToolbar")->toggleViewAction()->setChecked(false);

It seems that it's (quite) the right way, but we're definitely missing a part...
Any hint or idea to troubleshot ? 

Have a great day ! ^.^
Luc, Sebastien & Louka
