How to add QPushButton to QTreeWidget

[shamas]

Hi wysota-san,

Although very happy to hear back from you, I am now more confused than ever.

Here is what I now think so far.

I can make object of QTreeWidget and use QStandardItem. On QTreeWidgetItem object, I can call setIndexWidget to set a QPushButton where I wish. But that doesn't make sense since you initially discouraged saying that I should use QAbstractItemView::setIndexWIdget(), but I can have QAbstractItemView display since it's an Abstract Class.

Please. SOS.

setIndexWidget() is a method defined in QAbstractItemView but it is inherited by its subclasses (such as QTreeView or QTreeWidget) acording to rules of object oriented programming. And you shouldn't use setIndexWidget.

Hi,
So as it turns out that to choose which of my columns in which rows needed to be click-able/editable, I could do that by setData(columnNumber, Qt.UserRole, "isDisabled") and using QtItemDelegate for QtreeWidget's setItemDelegate. Each time a certain box is double clicked, I can see if its data has userRole defined is "isDisabled" in which case it would return null.

As far as the button was concerned, is set them as setData(columnNumber, Qt.UserRole, "shouldBehaveAsButton"), and when those are clicked, in QtItemDelegate, I would return null, and send command for button clicked. (Probably not a very user friendly idea, but will set colors or backgrounds in a way that it would look like a button and include this in my video demo)

This solves my problem. Thanks you.

There is an easier way. Each item in the model has a set of flags returned by QAbstractItemModel::flags(). Those flags include Qt::ItemIsEditable and Qt::ItemIsEnabled.
