Margins around QWidget - Unwanted

[Jake123]

Hello,

I seem to be getting a white margin or border that I have never got before, but it is disrupting my background image and basically very unsightly!

Here is my code:

MainMenu::MainMenu(QWidget *parent)
    : QWidget(parent)
 
{
 
 
    QSize Appsize(1200,650);
    QSize buttonsize(200,68);
    QSize helpbuttonsize(50,50);
 
 
 
 
    QPushButton *MainMenuButton = new QPushButton(this);
    QPushButton *QuadraticButton = new QPushButton(this);
    QPushButton *PythagorasButton = new QPushButton(this);
    QPushButton *TrigonometryButton = new QPushButton(this);
    QPushButton *SimButton = new QPushButton(this);
    QPushButton *TwoDButton = new QPushButton(this);
    QPushButton *ThreeDButton = new QPushButton(this);
    QSpacerItem *Spacer0001 = new QSpacerItem(100, 450, QSizePolicy::Ignored, QSizePolicy::Ignored);
             MainMenuButton -> setFixedSize(buttonsize);
            QuadraticButton -> setFixedSize(buttonsize);
            PythagorasButton -> setFixedSize(buttonsize);
            TrigonometryButton -> setFixedSize(buttonsize);

         setLayout(layout);
}

To copy to clipboard, switch view to plain text mode 

Unfortunately I have had to shorted the code quite significantly as it was around 30,000 characters but I have only removed other pages buttons and layouts which are the same as the mainmenu
Any help on this topic would be greatly appreciated, or just something to go and read so that I can fix it - I think it could be because of the stackedwidget as I haven't experienced this before.

Thanks
