My layout doesn't work

[mant]

Hi everyone. I'm creating a layout for my app.
I want the two widget to be displayed on the left and the RenderWidget be on the right.
Here is my code but the RenderWidget is not displayed.

@MainUI::MainUI()
{
m_ObjectListWidget = new QListWidget;
m_PhysicsConfModel = new QStandardItemModel(3, 2, this);
m_PhysicsConfWidget = new QTableView;
m_RenderWidget = new QWidget;
m_InfoWidget = new QWidget;
m_MainWidget = new QWidget;

m_HBoxLayout = new QHBoxLayout;
m_VBoxLayout = new QVBoxLayout;

m_RenderWidget->setAttribute(Qt::WA_PaintOnScreen);

m_PhysicsConfWidget->setModel(m_PhysicsConfModel);

m_VBoxLayout->addWidget(m_PhysicsConfWidget);
m_VBoxLayout->addWidget(m_ObjectListWidget);

m_InfoWidget->setLayout(m_VBoxLayout);

m_HBoxLayout->addWidget(m_InfoWidget);
m_HBoxLayout->addWidget(m_RenderWidget);

m_MainWidget->setLayout(m_HBoxLayout);

resize(800, 600);

setCentralWidget(m_MainWidget);

}@

I tried commenting out the line m_InfoWidget->setLayout(m_VBoxLayout);
which made the InfoWidget be an empty Widget and it worked like this:

But I can not add two widgets to the InfoWidget on the left and display it with a QVBoxLayout. Anyone can help me to fix this?
I'm using Qt 4.8.6 with CodeBlocks (MinGW) on an XP 32bit.
Thank you.

Hi,

Does something like:
@
m_ObjectListWidget = new QListWidget;
m_PhysicsConfWidget = new QTableView;
m_RenderWidget = new QWidget;
m_MainWidget = new QWidget;

m_VBoxLayout = new QVBoxLayout;
m_VBoxLayout->addWidget(m_PhysicsConfWidget);
m_VBoxLayout->addWidget(m_ObjectListWidget);

m_HBoxLayout = new QHBoxLayout(m_MainWidget);
m_HBoxLayout->addLayout(m_VBoxLayout);
m_HBoxLayout->addWidget(m_RenderWidget);

setCentralWidget(m_MainWidget);

@

work ?

Even if I remove the renderer and add a empty widget the result is still the same as picture 1.
@MainUI::MainUI()
{
m_ObjectListWidget = new QListWidget;
m_PhysicsConfModel = new QStandardItemModel(3, 2, this);
m_PhysicsConfWidget = new QTableView;
m_RenderWidget = new QWidget;
m_InfoWidget = new QWidget;
m_MainWidget = new QWidget;

m_HBoxLayout = new QHBoxLayout;
m_VBoxLayout = new QVBoxLayout;

m_RenderWidget->setAttribute(Qt::WA_PaintOnScreen);

m_PhysicsConfWidget->setModel(m_PhysicsConfModel);

m_VBoxLayout->addWidget(m_PhysicsConfWidget);
m_VBoxLayout->addWidget(m_ObjectListWidget);

m_InfoWidget->setLayout(m_VBoxLayout);

QWidget* x = new QWidget;

m_HBoxLayout->addWidget(m_InfoWidget);
m_HBoxLayout->addWidget(x);

m_MainWidget->setLayout(m_HBoxLayout);

resize(800, 600);

setCentralWidget(m_MainWidget);

}@

The sample SGaist posted should work. In your screen capture the right side is a little wider then the left so I think it is there but there it has no reason to be wider than what it is.

A small variation to test this assumption:

@
m_ObjectListWidget = new QListWidget;
m_PhysicsConfWidget = new QTableView;
m_RenderWidget = new QWidget;
m_MainWidget = new QWidget;

 m_RenderWidget->setMinimumWidth(100);

    m_VBoxLayout = new QVBoxLayout;
    m_VBoxLayout->addWidget(m_PhysicsConfWidget);
    m_VBoxLayout->addWidget(m_ObjectListWidget);
 
    m_HBoxLayout = new QHBoxLayout(m_MainWidget);
    m_HBoxLayout->addLayout(m_VBoxLayout);
    m_HBoxLayout->addWidget(m_RenderWidget);
 
    setCentralWidget(m_MainWidget);
