Problems to add QWidget to a Scroll Area...

[dcbasso]

I create one Widget that will be put inside a scrollarea, but my Widget is not appearing int the window.

@
WidgetSVG* widgetSVG = new WidgetSVG( );
widgetSVG->setVeiculo( veic );
ui->scrollAreaWidgetContents->layout()->addWidget( widgetSVG );
@

No error is showed, nothing wrong in the output...

I make this code, and the buttton appears.
The problem appears to be on WidgetSVG!!!

@
QPushButton* teste = new QPushButton();
teste->setText( "TESTE!!" );
ui->scrollAreaWidgetContents->layout()->addWidget( teste );
WidgetSVG* widgetSVG = new WidgetSVG( veiculo );
ui->scrollAreaWidgetContents->layout()->addWidget( widgetSVG );
