FomLay out and its size

[BinuJanardhanan]

I am using spinbox and label in each row of Form layout.
I resized the spinbox. and add it to the form layout.
but the size of the form layout is not equal to the widgets in it.

below code, i have used.

m_spinFreq= new QSpinBox();
   m_spinFreq->setFixedSize(QSize(100,35));
   m_spinPhase= new QSpinBox();
   m_spinPhase->setFixedSize(QSize(100,35));
   m_spinTE= new QSpinBox();
   m_spinTE->setFixedSize(QSize(100,35));
   m_spinTR= new QSpinBox();
   m_spinTR->setFixedSize(QSize(100,35));
m_labFreq->setText("Freq");
   m_labPhase= new QLabel();
   m_labPhase->setText("Phase");
   m_labTE= new QLabel();
   m_labTE->setText("TE (ms)");
   m_labTR= new QLabel();
   m_labTR->setText("TR (ms)");
m_formLayBasicOne=new QFormLayout();
m_formLayBasicOne->setSpacing(30);  

   m_formLayBasicOne->setLabelAlignment(Qt::AlignVCenter);
   m_formLayBasicOne->addRow(m_labFreq,m_spinFreq);
   m_formLayBasicOne->addRow(m_labPhase,m_spinPhase);
   m_formLayBasicOne->addRow(m_labTE,m_spinTE);
   m_formLayBasicOne->addRow(m_labTR,m_spinTR);
   m_formLayBasicOne->setSpacing(30);
this->setLayout(m_formLayBasicOne);

Output

I want to fix the layout size to its widget. ?
Here widget in form layout occupied less space but too much free space is there. how can I avoid free space of right and bottom?

@BinuJanardhanan ,

You are calling setSpacing twice. Set some minimum size to your main widget.

widgetWithFormLayout->setSizePolicy( QSizePolicy::Fixed, QSizePolicy::Fixed );
