Any reason why you can't use QStandardItemModel? in that case subclass QStyledItemDelegate and reimplement paint void QStyledItemDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const { Q_ASSERT(index.isValid()); QStyleOptionViewItem opt = option; initStyleOption(&opt, index); ///////////////////////////////////// // Set the background based on the content if(index.data().toInt()==1) opt.backgroundBrush = QBrush(Qt::red); ///////////////////////////////////// const QWidget *widget = option.widget; QStyle *style = widget ? widget->style() : QApplication::style(); style->drawControl(QStyle::CE_ItemViewItem, &opt, painter, widget); }

I figured out the answer. I have to create a QSlider from scratch meaning not one created from the ui already. So, QSlider *slider = new MySlider(Qt::horizontal); ui->frameTestLayout->addWidget(slider); slider->setFocusPolicy(Qt::NoFocus); slider->setTickPosition(QSlider::TicksAbove); slider->setTickInterval(number);

@Mikkie I am facing a similar issue. I fetch frames from linux machine(server) and displaying them on a windows machine(client). The image I see in R and B swapped. (I have use QImage to draw image onto a QWidget) QImage((uchar*)buffer, widht , height , QImage::Format_RGB888) If I dump the contents of the buffer received into a file and open it using Windows Image Viewer I observe the Colors in expected format.

@Chris-Kawa Thanks to you I've been able to solve

Hi and welcome to devnet, Since you are using an unreleased version of Qt and hitting something that's probably influenced by the internals of Qt. I'd recommend posting your question on the interest mailing list You'll find there Qt's developers/maintainers (this forum is more user oriented)

Hi, Depending on how your button should look like, Qt's stylesheet system might be the most simple solution Hope it helps
