How to show progess in a QTreeView item ?

[wysota]

No, it won't.

class Dele : public QItemDelegate {
public:
  void paint(QPainter *p, const .... &opt, const QModelIndex &ind const {
    int val = ind.data(Qt::DisplayRole).toInt();
    QRect rect = opt.rect;
    rect.setWidth(rect.width()*val/100);
    p->drawRect(rect);
  }
};
 
QTreeWidget Item *item = ....
 
item->setText(1, 40);
// view will be updated here
item->setText(1, 60);
// view will be updated here

class Dele : public QItemDelegate {
public:
  void paint(QPainter *p, const .... &opt, const QModelIndex &ind const {
    int val = ind.data(Qt::DisplayRole).toInt();
    QRect rect = opt.rect;
    rect.setWidth(rect.width()*val/100);
    p->drawRect(rect);
  }
};

QTreeWidget Item *item = ....

item->setText(1, 40);
// view will be updated here
item->setText(1, 60);
// view will be updated here

To copy to clipboard, switch view to plain text mode 

You have at least two almost complete solution on the very first page of this thread. Didn't you see them?

Thanks that is what I was asking you

And one more question I'd like to ask. I don't know if this is the right topic so don't blame me too much

The problem is when I click on a row in my table widget it becomes highlighted but when I use delegates it is not. I've tried to do like this

if (table->currentRow() == index.row())
{
 painter->setBrush(QBrush(QColor("#444444")));
 painter->drawRect(opt.rect);
}

if (table->currentRow() == index.row())
{
 painter->setBrush(QBrush(QColor("#444444")));
 painter->drawRect(opt.rect);
}

but it didn't work the way I thought. Also I've tried to use setBackground with QPainter and that didn't work either

The QStyleOptionViewItem parameter contains all required information.

if (opt.state & QStyle::State_Selected)
   ...
 
if (opt.state & QStyle::State_HasFocus)
   ...

if (opt.state & QStyle::State_Selected)
   ...

if (opt.state & QStyle::State_HasFocus)
   ...

To copy to clipboard, switch view to plain text mode 

etc.

And what after ???
I've tried like

if (opt.state & QStyle::State_Selected)
	{
		painter->setBrush(QBrush(QColor("#444444")));
		painter->drawRect(opt.rect);
	}

if (opt.state & QStyle::State_Selected)
	{
		painter->setBrush(QBrush(QColor("#444444")));
		painter->drawRect(opt.rect);
	}
