Hi,
I trying to layout my widgets but it doesn't work.

I would create 2 widget with a fixed hight and an expanding width but it doesn't work.
I create them so:

Qt Code: 
  1. CentralWidget::CentralWidget( QWidget* parent /* = 0 */ ) 
  2. : QWidget(parent),
  3.   mp_vBox( 0 ),
  4.   m_pWaveU( 0 ),
  5.   m_pWaveD( 0 )
  6. {
  7. 	/* vertical LAYOUT */
  8. 	mp_vBox = new QVBoxLayout( this );
  9.  
  10. 	/* 2 WAVEFORM DISPLAY */
  11. 	m_pWaveU = new WaveDisplay( this );
  12. 	m_pWaveU->setGeometry(0, 0,200,150); // I would for this a fixed geometry in height
  13. 	m_pWaveU->setSizePolicy( QSizePolicy::Ignored, QSizePolicy::Minimum );//I WOULD THIS WITH A FIXED HEIGHT AND THAT IT CAN EXPAND HORIZONTALY
  14.  
  15. 	m_pWaveD = new WaveDisplay( this );
  16. 	m_pWaveD->setSizePolicy( QSizePolicy::Ignored, QSizePolicy::Ignored );
  17. 	mp_vBox->addWidget( m_pWaveU );
  18. 	mp_vBox->addSpacing( 15 );
  19. 	mp_vBox->addWidget( m_pWaveD );
  20. 	setLayout(mp_vBox);
  21. }
