ScrollArea in a tabWidget

[Yaoming]

I've done what you told me but it's still not working. Here's what I have: art.jpgqsd.jpg.
I don't know how to have just one scrollbar that would be shown whenever my current tab content is bigger than the tab's size. I could use a QVerticalScrollBar perhaps? That might be harder I don't know...

This looks like the text edit being a cild of the tab instead of being inside the scrollarea.

Since you want more than one widget inside the scrollarea, add a normal and empty QWidget into it, see QScrollArea::setWidget()
Then add your text edits to that widget, using whatever layout you find appropriate.

I've done what you told me but the scrollbars are not showing up. My code:

//my constructor
        container = new QWidget();   //the empty widget
	ui.scrollArea->setWidget(container);  //that I add to my scrollArea
//this my text Edit's creation
        txt = new QTextEdit(container);  //I create my textEdit and set its parent to the created widget
	connect(txt->document(), SIGNAL(contentsChanged()), this, SLOT(update_size()));
	txt->installEventFilter(this);
	txt->setFont(QFont("Times New Roman", fontSize));
	txt->setTextColor(fontColor);
	txt->show();

//my constructor
        container = new QWidget();   //the empty widget
	ui.scrollArea->setWidget(container);  //that I add to my scrollArea
//this my text Edit's creation
        txt = new QTextEdit(container);  //I create my textEdit and set its parent to the created widget
	connect(txt->document(), SIGNAL(contentsChanged()), this, SLOT(update_size()));
	txt->installEventFilter(this);
	txt->setFont(QFont("Times New Roman", fontSize));
	txt->setTextColor(fontColor);
	txt->show();

To copy to clipboard, switch view to plain text mode

The container does not have a layout. So if the size of the text edit increases it does not increase the size of the container.

How do you suggest that I do that? I tried that but still not working:

container = new QWidget();
	layout = new QVBoxLayout();
	ui.scrollArea->setWidget(container);
	container->setLayout(layout); 
	ui.scrollArea->setWidgetResizable(true);

container = new QWidget();
	layout = new QVBoxLayout();
	ui.scrollArea->setWidget(container);
	container->setLayout(layout); 
	ui.scrollArea->setWidgetResizable(true);

Yes, like that.

I just did a quick experiement in designer and I get scroll bars when the scroll area is smaller than the text edits inside it.
Form.ui

Could you please give me your code? Because what I have is not working... I've tried different ways but in vain.

[anda_skoa]

The designer ui file is attached, the Form.ui is a link.

Ok but you did it with Designer. In my case, I can't... Here's all my code for this part, do you see any mistakes? Would you have done it differently?

//my .h file
QVBoxLayout* layout;
QTextEdit* txt;
QWidget* container;
 
//my .cpp file
  //Constructor
  	container = new QWidget();
	layout = new QVBoxLayout();
	ui.scrollArea->setWidget(container);
	container->setLayout(layout);
	ui.scrollArea->setLayout(layout);
	ui.scrollArea->setWidgetResizable(true);
 
  //Slot which creates my textEdits
	txt = new QTextEdit();
	txt->setParent(container);
	connect(txt->document(), SIGNAL(contentsChanged()), this, SLOT(update_size()));
	txt->installEventFilter(this);
	txt->setFont(QFont("Times New Roman", fontSize));
	txt->setTextColor(fontColor);
	txt->show();

//my .h file
QVBoxLayout* layout;
QTextEdit* txt;
QWidget* container;

//my .cpp file
  //Constructor
  	container = new QWidget();
	layout = new QVBoxLayout();
	ui.scrollArea->setWidget(container);
	container->setLayout(layout);
	ui.scrollArea->setLayout(layout);
	ui.scrollArea->setWidgetResizable(true);

  //Slot which creates my textEdits
	txt = new QTextEdit();
	txt->setParent(container);
	connect(txt->document(), SIGNAL(contentsChanged()), this, SLOT(update_size()));
	txt->installEventFilter(this);
	txt->setFont(QFont("Times New Roman", fontSize));
	txt->setTextColor(fontColor);
	txt->show();

You are missing the layout->addWidget(txt) call.

Still not working... Anyway you've helped me a lot so I'm going to try and figure it out by myself and stop bothering you.
Thanks for your help
