Simple QScrollArea problem

[jmsbc]

Hi,

I'm not seeing my widget window when I'm trying put it into a QScrollArea with QFrame.

I designed a gui (MyWidget) using designer.

I placed all the buttons of my gui inside of a QFrame (like Wysota suggested in another thread), and then promoted the QFrame to QScrollArea and called it scrollFrame.

So in my code, my constructor looks like this:

MyWidget::MyWidget (QWidget *parent, Qt::WFlags flags)
	: QWidget(parent, flags)
{
  ui.setupUi(this);
  ui.scrollFrame->setWidget(this);
}

MyWidget::MyWidget (QWidget *parent, Qt::WFlags flags)
	: QWidget(parent, flags)
{
  ui.setupUi(this);
  ui.scrollFrame->setWidget(this);
}

To copy to clipboard, switch view to plain text mode 

My main looks like this:

int main(int argc, char *argv[])
{
  QApplication a(argc, argv);
  MyWidget w;
  w.show();
 
  return a.exec();
}

int main(int argc, char *argv[])
{
  QApplication a(argc, argv);
  MyWidget w;
  w.show();

  return a.exec();
}

To copy to clipboard, switch view to plain text mode 

However nothing shows up when I try to run this. Can somebody please help me figure out how to bring up the scrollbars?

Thank you.

Hi,

ui.setupUi(this);
ui.scrollFrame->setWidget(this);

ui.setupUi(this);
ui.scrollFrame->setWidget(this);

To copy to clipboard, switch view to plain text mode 

I'm sorry, but this code doesn't make any sense. You have a window. First you load a designed form on the window. At this stage the window contains a scroll area. Then you try to set the window inside that scroll area.

PS. Please don't double post!

Crap you're right sorry about that.

Let's say I have a calendar widget inside of the QScrollArea's QFrame and then I do

ScrollTest::ScrollTest(QWidget *parent, Qt::WFlags flags)
    : QMainWindow(parent, flags)
{
  ui.setupUi(this);
  ui.scrollFrame->setWidget(ui.calendarWidget);
}

ScrollTest::ScrollTest(QWidget *parent, Qt::WFlags flags)
    : QMainWindow(parent, flags)
{
  ui.setupUi(this);
  ui.scrollFrame->setWidget(ui.calendarWidget);
}

To copy to clipboard, switch view to plain text mode 

This will show me the window with calenderWidget, but when I resize the window smaller than the calendar, scrollbars do not show up.

I'm probably doing something really wrong, please help!

You're probably missing the top level layout. See Setting A Top Level Layout for more details.
