no horizontal scroll bar in QTableWidget

hi.
i want to create search results window, so i put QTextBrowsers in QTableWidget's cells using setCellWidget. there is a problem: horizontal scroll bar in QTableWidget is never appears in contrast to the vertical, which is appears when its needed. all scroll bar settings are default.
how can i get this scroll when its needed? and even when i set horizontalScrollBarPolicy in alwaysOn, there is no slider on it even when it should be.
and also how to adjust table's cell size to full browser's text size?
there is some sample code

Code:

---

// ui->tw is a QTableWidget
    ui->tw->insertRow(0);
    b = new QTextBrowser(ui->tw);
    b->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    b->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    b->setWordWrapMode(QTextOption::NoWrap);
    b->setHtml(tr("some <b>HTML</b> <i>marked</i> search result <u>that does not fit in table cell without scroll bar</u>"));
    ui->tw->setCellWidget(0,0,b);

---

Code:

---

setHorizontalScrollBarPolicy(Qt::ScrollBarAsNeeded);

its not working. Qt::ScrollBarAsNeeded is a default value that used in designer. i tried to set it manualy, thats what i got:Attachment 8313

I think this is because you have only one column (at least it seems so from the picture) and the column (not its contents) is visible so scrolling is not needed.

try this: change the scrolling mode to ScrollPerPixel and set a minimum width for the QTableWidget's horizontal header, for example

Code:

---

tb.setHorizontalScrollMode(QAbstractItemView::ScrollPerPixel);
tb.horizontalHeader()->setMinimumWidth(minwidth);

---

here tb is QTableWidget.

it works too. thanks!

Putting text browser instances in QTableWidget is not the right thing to do here. If you need rich text (I'm assuming that's why you put QTextBrowser there), you should implement a rich text delegate for your table widget.
