Hi and welcome to devnet,

Looks like you rather want to use QSplitter for that

Thank you for your help. I have subclass the QSortFilterProxyModel and set flags returns Qt::ItemIsUserCheckble. it worked well

Super!
Good work
Remember to mark it as SOLVED ifpossible.
Happy coding :)

You just need a little cheat on the standard delegate

class PositiveDelegate : public QStyledItemDelegate{ Q_OBJECT Q_DISABLE_COPY(PositiveDelegate) public: explicit PositiveDelegate(QObject* parent=Q_NULLPTR) :QStyledItemDelegate(parent) {} virtual QWidget* createEditor(QWidget *parent, const QStyleOptionViewItem& option, const QModelIndex &index) const{ QWidget* result = QStyledItemDelegate::createEditor(parent,option,index); QSpinBox* intSpinRes = qobject_cast<QSpinBox*>(result); if(intSpinRes ){ intSpinRes ->setMinimum(0); return intSpinRes; } QDoubleSpinBox* doubSpinRes = qobject_cast<QDoubleSpinBox*>(result); if(doubSpinRes ){ doubSpinRes ->setMinimum(0.0); return doubSpinRes ; } return result; } };

Hi and welcome

Maybe
void QDrag::setPixmap(const QPixmap & pixmap)
Could be used ?
You set it when you start the drag so it sounds it might do what you want.

Hi

I would say a Delegate would be the way to do it.
Have a look at
"Star Delegate Example"

For your fancy hand, you can use
QApplication::setOverrideCursor(QCursor(Qt::PointingHandCursor));
QApplication::restoreOverrideCursor();

Its also possible via the model

Hi
If I read
http://doc.qt.io/qt-4.8/stylesheet-reference.html#list-of-properties

It says that
text-align
only supported for QPushButton and QProgressBar.

Cannot find any sign that it has changed for 5.5

So its via Delegate or the model.

Hi,

Looks like a work for a QAbstractProxyModel derived class

Hi,

That would rather be something to do in the your model or using a QIdentityProxyModel

@mrjj

OK but I use the class to encapsulate all data and logics on that data. The collection of all data to fill drop-down boxes, lists reports etc... are all in the class together with the hiding of the record data by get and put protection. So if I have to create an instance every time, I'll spend a whole needless bunch of heap for every list. If I use static functions it's more memory friendly :-)

I have studied the model/view stuff of Qt almost the same thing was used by MS in the MFC time a 20 years ago, they also had a Data/View structure, but then we programmed still in C. So my ignorance is situated there that I have little C++ experience, just played a little with it in the time of Turbo Borland C++ a long time ago.

Professionally I'm a MS programmer but for my son I'm developing a whole suite on Linux and Mono did not give me what I was used to so I switched to Qt and C++. This way the old man has to study again. But it keeps the mind young...

Thanks a lot
Jean Paul

@hamov

well digging around, I also found
m_list->viewport()->repaint();

which works for WidgetList. Did not test with model/view yet.

I think it is by design as it does redraw when data changes but we are not alone finding
it strange working if one google it

Hi and welcome to devnet,

You should take a look at the QStyledItemDelegate. It will allow you to present your data the way you want.

Hope it helps

@SGaist
Yes, It worked me out.

HI and welcome to devnet,

you can connect a slot to the QHeaderView::sectionResized() signal to be notified when a column is resized

connect(tableView->horizontalHeader(), &QHeaderView::sectionResized, this, &MyWIdget::slotColumnResized);

Sorry for the late reply, the page says that there's nothing to be found
