Handle Spacing on Gridlayout with hidden elements

[PeterSilie]

Hello,

I am using a GridLayout (QT 4.8.7) and on certain actions i hide/show parts inside this layout using .hide()/.show().



The Problem which now occurs is that the spacing of these hidden elements is still shown inside the layout (see picture).

layout = new QGridLayout( this );
layout->setMargin( 1 );
layout->setSpacing( 1 );
 
setSizePolicy( sizePolicy().horizontalPolicy(), QSizePolicy::Fixed );

layout = new QGridLayout( this );
layout->setMargin( 1 );
layout->setSpacing( 1 );

setSizePolicy( sizePolicy().horizontalPolicy(), QSizePolicy::Fixed );

To copy to clipboard, switch view to plain text mode 

Is there a simple way to prevent this behaviour?
