layout for display functions

[therealjag]

hey there i am making a grid layout and i have 2 QLineEdit displayboxs with 1 under the other. is there a way to make the display boxes smaller in width:

display = new QLineEdit("0");
     display->setReadOnly(true);
     display->setAlignment(Qt::AlignCenter);
     display->setMaxLength(10);
     display->installEventFilter(this);
     QFont font = display->font();
     font.setPointSize(font.pointSize() + 8);
     display->setFont(font);
 
     display2 = new QLineEdit("0");
     display2->setReadOnly(true);
     display2->setAlignment(Qt::AlignCenter);
     display2->setMaxLength(10);
     display2->installEventFilter(this);
     QFont font2 = display2->font();
     font2.setPointSize(font2.pointSize() + 8);
     display2->setFont(font2);

display = new QLineEdit("0");
     display->setReadOnly(true);
     display->setAlignment(Qt::AlignCenter);
     display->setMaxLength(10);
     display->installEventFilter(this);
     QFont font = display->font();
     font.setPointSize(font.pointSize() + 8);
     display->setFont(font);
    
     display2 = new QLineEdit("0");
     display2->setReadOnly(true);
     display2->setAlignment(Qt::AlignCenter);
     display2->setMaxLength(10);
     display2->installEventFilter(this);
     QFont font2 = display2->font();
     font2.setPointSize(font2.pointSize() + 8);
     display2->setFont(font2);

To copy to clipboard, switch view to plain text mode

Set size hints for the line edits or use spacer items to "pack" them to a certain corner.

You can use different sizePolicy settings to manipulate the behaviour of widgets.
