Scroll Area inside Dock Widget

[saransiva_ps]

Hi,

I've used the following code snippet to add scroll area inside dock widget

QDockWidget *m_pMapInfoWidget = new QDockWidget(this);
	m_pMapInfoWidget->setObjectName(QStringLiteral("Map Info Widget"));
 
	m_pMapInfoWidget->setFeatures(QDockWidget::NoDockWidgetFeatures);
	m_pMapInfoWidget->setAllowedAreas(Qt::RightDockWidgetArea);
	m_pMapInfoWidget->setMinimumSize(285, 500);
 
	addDockWidget(Qt::RightDockWidgetArea, m_pMapInfoWidget);
 
        // Create scroll area for the widget
	QScrollArea *m_pMapInfoScrollArea = new QScrollArea();
	m_pMapInfoScrollArea->setObjectName(QStringLiteral("MapInfoScrollArea"));
	m_pMapInfoScrollArea->setWidgetResizable(true);
	m_pMapInfoScrollArea->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOn);
	m_pMapInfoScrollArea->setFrameStyle(QFrame::NoFrame);
	m_pMapInfoScrollArea->show();
 
	// Scroll area content
	QWidget *m_pInfoContent = new QWidget();
	m_pInfoContent->setObjectName(QStringLiteral("InfoContent"));
 
        QGroupBox *m_pGPSGroupBox = new QGroupBox(m_pInfoContent);
        m_pGPSGroupBox->setObjectName(QStringLiteral("GPSGroupBox"));
        m_pGPSGroupBox->setFont(infoFont);
 
	m_pGPSGroupBox->setTitle("Heading");
	m_pGPSGroupBox->setGeometry(QRect(3, 20, 270, 170));
 
 
        QLabel *m_pLatLabel = new QLabel(m_pGPSGroupBox);
        m_pLatLabel->setObjectName(QStringLiteral("LatLabel"));
        m_pLatLabel->setGeometry(QRect(20, 30, 51, 16));
        m_pLatLabel->setFont(infoFont);
	m_pLatLabel->setText("Latitude");
 
        m_pMapInfoScrollArea->setWidget(m_pInfoContent);
        m_pMapInfoWidget->setWidget(m_pMapInfoScrollArea);

QDockWidget *m_pMapInfoWidget = new QDockWidget(this);
	m_pMapInfoWidget->setObjectName(QStringLiteral("Map Info Widget"));
	
	m_pMapInfoWidget->setFeatures(QDockWidget::NoDockWidgetFeatures);
	m_pMapInfoWidget->setAllowedAreas(Qt::RightDockWidgetArea);
	m_pMapInfoWidget->setMinimumSize(285, 500);
		
	addDockWidget(Qt::RightDockWidgetArea, m_pMapInfoWidget);

        // Create scroll area for the widget
	QScrollArea *m_pMapInfoScrollArea = new QScrollArea();
	m_pMapInfoScrollArea->setObjectName(QStringLiteral("MapInfoScrollArea"));
	m_pMapInfoScrollArea->setWidgetResizable(true);
	m_pMapInfoScrollArea->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOn);
	m_pMapInfoScrollArea->setFrameStyle(QFrame::NoFrame);
	m_pMapInfoScrollArea->show();
	
	// Scroll area content
	QWidget *m_pInfoContent = new QWidget();
	m_pInfoContent->setObjectName(QStringLiteral("InfoContent"));

        QGroupBox *m_pGPSGroupBox = new QGroupBox(m_pInfoContent);
        m_pGPSGroupBox->setObjectName(QStringLiteral("GPSGroupBox"));
        m_pGPSGroupBox->setFont(infoFont);
	
	m_pGPSGroupBox->setTitle("Heading");
	m_pGPSGroupBox->setGeometry(QRect(3, 20, 270, 170));


        QLabel *m_pLatLabel = new QLabel(m_pGPSGroupBox);
        m_pLatLabel->setObjectName(QStringLiteral("LatLabel"));
        m_pLatLabel->setGeometry(QRect(20, 30, 51, 16));
        m_pLatLabel->setFont(infoFont);
	m_pLatLabel->setText("Latitude");

        m_pMapInfoScrollArea->setWidget(m_pInfoContent);
        m_pMapInfoWidget->setWidget(m_pMapInfoScrollArea);

To copy to clipboard, switch view to plain text mode 

When executing the above code we are getting a scroll area, but there is no scroll bar in it.
When i resize the window, we are not getting the scroll bar.
Kindly help us to resolve this.

Show after setting the widget, like this...

//m_pMapInfoScrollArea->show(); //<<<<<<<<<<<<<<<<<<<<<<<<
...
m_pMapInfoScrollArea->setWidget(m_pInfoContent);
m_pMapInfoWidget->setWidget(m_pMapInfoScrollArea);
m_pMapInfoWidget->show()

//m_pMapInfoScrollArea->show(); //<<<<<<<<<<<<<<<<<<<<<<<<
...
m_pMapInfoScrollArea->setWidget(m_pInfoContent);
m_pMapInfoWidget->setWidget(m_pMapInfoScrollArea);
m_pMapInfoWidget->show()

To copy to clipboard, switch view to plain text mode

Hi,

Thanks for the reply. After adding

m_pMapInfoWidget->show();

m_pMapInfoWidget->show();

To copy to clipboard, switch view to plain text mode 

We are not able to get the scroll bar. After searching we found that a minimum size must be specified for the Content widget (holding the info)
to get the scroll bar. That is

m_pInfoContent->setMinimumSize(280, 1200);

m_pInfoContent->setMinimumSize(280, 1200);

To copy to clipboard, switch view to plain text mode 

Thanks
