Can't change QHBoxLayout geometry

[gutiory]

Hello people,

I have a problem (very easy it seems) that I can't find the solution.
I've a widget with QHBoxLayout in it and I would like to change the geometry of the layout. I thought it was enough by using setGeometry(), but it doesn't work.
I have also notice that x and y components of the layout are 0.

I hope you can help me.

Regards.

Hi
Code please !

Hello and thaks for your answer.

I'm sorry, but I thought It wasn't necessary to include the code for changing the geometry of a layout.

Here is my code

void CWGraficaSimple::resizeEvent(QResizeEvent *event)
{
 
    QRect hboxRect = ui.hboxLayout->geometry();
    int difVer = event->size().height() - event->oldSize().height();
 
    ui.hboxLayout->setGeometry( QRect(hboxRect.x(),  hboxRect.y() + difVer, hboxRect.width(), hboxRect.height()));
 
}

void CWGraficaSimple::resizeEvent(QResizeEvent *event)
{
   
    QRect hboxRect = ui.hboxLayout->geometry();
    int difVer = event->size().height() - event->oldSize().height();

    ui.hboxLayout->setGeometry( QRect(hboxRect.x(),  hboxRect.y() + difVer, hboxRect.width(), hboxRect.height()));
			
}

To copy to clipboard, switch view to plain text mode 

I just want to "move" the y cordenate of the layout.

Thanks a lot again.

Perhaps your layout doesn't have any related QWidget to provide the geometry.

You can try this:

QWidget* layoutWidget = new QWidget();
layoutWidget.setLayout(ui.hboxLayout);
layoutWidget.setGeometry(100,100,200,200);

QWidget* layoutWidget = new QWidget();
layoutWidget.setLayout(ui.hboxLayout);
layoutWidget.setGeometry(100,100,200,200);

To copy to clipboard, switch view to plain text mode

Thanks a lot MorrisLang!!!!.
You were completly wright. I just added a widget and put a widget into. After that I set the layout inside the widget and I only have to move the widget.

Thanks again.

Regards.

Layouts act like containers for widgets and have their own intelligence how to set widgets.
You should use layouts geaometry, instead the widgets geometry as mentioned above.

No,I don't think so.According to the doc,"The widget will get an event of type QEvent::LayoutRequest when the layout needs to be recalculated".Layout relies on a QWidget to calculate the size.
