QTreeWidget, resizing item and widgets problem

1. I don't use QItemDelegate,

Of course you do. Each cell is painted using a delegate and the default delegate is QItemDelegate or QStyledItemDelegate since Qt 4.4.

2. I use setAutofillBackground(true) to my QFrame widget if it's that whats you meant but no change...

Try changing the palette of the frame (especially the Window role) to see if the background of the frame gets painted.

I hope that this is what you meant (attached picture) and how can I be sure that this QItemDelegate doesn't paint anything while there is widget on it.

Yes. You can see that the frame doesn't span across the whole item. Could you show us the code for the widget you set as the index widget?

and how can I be sure that this QItemDelegate doesn't paint anything while there is widget on it.

Remove the icon when you set the index widget.

Here's the code

ContactWidget *pContactWidget = new ContactWidget();
pContactWidget->setAutoFillBackground(true);
/* Setting some data to the QLabels inside the pContactWidget */
pContactView->setItemWidget(selectedItem, 0, pContactWidget);

ContactWidget *pContactWidget = new ContactWidget();
pContactWidget->setAutoFillBackground(true);
/* Setting some data to the QLabels inside the pContactWidget */
pContactView->setItemWidget(selectedItem, 0, pContactWidget);

ContactWidget - my class that inherits QFrame
pContactView - this is the QTreeWidget

Sure removing of the icon from the item before setting the widget fix the problem but this was the thing I want to avoid because when the user click on other contact from the list I must set the icon of the item again and sinse my code is not very well constructed this is ugly task to be done but if there is no other way I will remove that icon before setting the widget.

Do you have a hierarchy of items or is your data model flat? Did you modify any properties in ContactWidget? What does the constructor look like?

[The Storm]

I don't use model, I'm directly creating new items, I do nothing in to my class that inherits QFrame, thats are future plans but I will show.

class ContactWidget : public QFrame
{
	Q_OBJECT
 
public:
	ContactWidget(QWidget *parent = 0) : QFrame(parent) {};
	~ContactWidget() {};
};

class ContactWidget : public QFrame
{
	Q_OBJECT

public:
	ContactWidget(QWidget *parent = 0) : QFrame(parent) {};
	~ContactWidget() {};
};

It's still a data model. So do you organize your items in a flat structure or a graph (parent-child relationship)?

[The Storm]

It's flat structure, there is no childs.

[wysota]

Could you just for testing issue such code and show us the result?

selectedItem->setData(Qt::blue, Qt::BackgroundRole);

selectedItem->setData(Qt::blue, Qt::BackgroundRole);

Ah I'm sorry but I already do remove the icon before setting the widget and all is fine, so I don't have what to show after I put this line of code, but if you really want to I will make some changes and make screenshot.
