[SOLVED] How to set Multiple QGroupBox alignment in QVBoxLayout

kloveridge

This is a seemingly basic issue. But I am having difficultly getting exactly what I want. I have a QVBoxLayout that I want to stack multiple QGroupBox widgets into. I want them to align from top to bottom and stay connected together. This is what happens by default:

I have tried several alignment settings. This will work, but is this the right way?

@ ui->NodeView->addWidget(m_nodeTransform);
ui->NodeView->addWidget(m_nodeCommon);

ui->NodeView->setAlignment(m_nodeCommon, Qt::AlignTop);@

Hi,
The empty space needs to be filled by something. Use a Vertical spacer below the last QGroupbox and your fine. OTherwise the layout will try to fill the available space with the widgets it has (the two groupboxes)

That worked. Thank you!

Here's a snippet of code that did it.

@QSpacerItem* spacer = new QSpacerItem(300,1000, QSizePolicy::Expanding, QSizePolicy::Expanding);
spacer->setAlignment(Qt::AlignVCenter);

ui->NodeView->addWidget(m_nodeTransform);
ui->NodeView->addWidget(m_nodeCommon);
ui->NodeView->addWidget(m_nodeDrawable);
ui->NodeView->addItem(spacer);@

Oke, glad it helped!
Here is some docs for you to solve other issues with layouts:
"LayoutManagement":http://qt-project.org/doc/qt-5/layout.html
Also, the use of addItem is not wrong, but it might be better to use this:
@
void QBoxLayout::addSpacerItem(QSpacerItem * spacerItem)
@
This is more appropriate.
