Howto: Setup QScrollArea correct? - e.g. scrolling is not working...

[Astronomy]

Hello again,

today i had the time to solve this problem with your suggestions
At: http://doc.trolltech.com/latest/qscr...html#setWidget
is the hint:
Note that You must add the layout of widget before you call this function; if you add it later, the widget will not be visible - regardless of when you show() the scroll area. In this case, you can also not show() the widget later.

With QLayout i had some problems, but at last:

I had to set the minimum size of my custom widget, before i add it to the scrollArea.
So everytime i change the size of pJob because of adding new functionyllity -eg widgets to it scrollArea will adapt automatically.

i did at my constructor:

...
m_ui->setupUi(this);
Jobs *pjob = new  Jobs();
 
QSize AdjustSize = pjob->size();    
AdjustSize.width();  // for debugging...
 
// Adjust scrollArea to this size,
pjob->setMinimumSize(AdjustSize);  // Advantage: everytime you change the size of pJob,
                                                // because of adding new functionyllity -eg widgets to it..
                                                // scrollArea will adapt automatically (-:  
 
m_ui->scrollArea->setWidgetResizable(true);
m_ui->scrollArea->setWidget(pjob);

...
m_ui->setupUi(this);
Jobs *pjob = new  Jobs();

QSize AdjustSize = pjob->size();    
AdjustSize.width();  // for debugging...
    
// Adjust scrollArea to this size,
pjob->setMinimumSize(AdjustSize);  // Advantage: everytime you change the size of pJob,
                                                // because of adding new functionyllity -eg widgets to it..
                                                // scrollArea will adapt automatically (-:  

m_ui->scrollArea->setWidgetResizable(true);
m_ui->scrollArea->setWidget(pjob);
