Widgets inside another widget should resize

[Pradeep Kumar]

HI,

I have one widget and added to QVBoxLayout
and one more widget set has parent .

m_widget = new QWidget;
    m_widget->setSizePolicy(QSizePolicy::Expanding,QSizePolicy::Expanding);

    m_anotherwidget = new CConfigurePTZ(m_widget);
    m_anotherwidget->setSizePolicy(QSizePolicy::Expanding,QSizePolicy::Expanding);

when i expand window m_widget is expanding, but the m_anotherwidget is not expanding.

How to achieve this .

Thanks,

Hi @Pradeep-Kumar

Try to add a layout to your m_widget, i think that this is the problem.

Hi,

i tried adding QHBoxLayout to m_widget, still not expanding

m_HBoxLayout = new QHBoxLayout;
m_HBoxLayout->addWidget(m_Widget);

still m_anotherwidget is not expanding.

@Pradeep-Kumar
close, but you have to define m_anotherwidget as part of your m_HBoxLayout.
Otherwise you have just 2 unrelated widgets lying ontop of each other.

You have to set your layout on a widget for it to do something.

[mostefa]

as @SGaist said

you have to add

m_widget->setLayout(m_HBoxLayout);

```

m_widget = new QWidget;
m_widget->setSizePolicy(QSizePolicy::Expanding,QSizePolicy::Expanding);

m_anotherwidget = new CConfigurePTZ(m_widget);
m_anotherwidget->setSizePolicy(QSizePolicy::Expanding,QSizePolicy::Expanding);

m_HBoxLayout = new QHBoxLayout;
m_HBoxLayout->addWidget(m_Widget);

i have a gridlayout and my hboxlayout setting it to vboxlayout.

m_pQVBoxLayout->addLayout(m_GridLayout);
m_pQVBoxLayout->addLayout(m_HBoxLayout);
this->setLayout(m_VBoxLayout);

how can i modify hboxlayout?.

Thanks,

[Pradeep Kumar]

can anyone suggest how this can be achieved?.

@Pradeep-Kumar said in Widgets inside another widget should resize:

What do you want to modify in hboxlayout?
You should really read about layouts in Qt.

You are confusing which widget should go in the layout and which widget the layout applies to

m_widget = new QWidget;
m_widget->setSizePolicy(QSizePolicy::Expanding,QSizePolicy::Expanding);

m_anotherwidget = new CConfigurePTZ(m_widget);
//m_anotherwidget->setSizePolicy(QSizePolicy::Expanding,QSizePolicy::Expanding);

QHBoxLayout* widgetLay = new QHBoxLayout(m_widget);
widgetLay->addWidget(m_anotherwidget);

m_VBoxLayout->addWidget(m_widget);
this->setLayout(m_VBoxLayout);
