How to add button to item QListView?

Question

Qt

There is a widget based on QListView to display the model. The model is based on QAbstractListModel.
Essentially a list of files is displayed. It is necessary to implement a button for each displayed item in the list. (I want a "cross" like in a QtCreator widget that displays a list of open documents)

Answer 1

QListView inherits from QAbstractItemView, and the latter has the ability to set delegates for custom cells:

// Для всех ячеек.
void setItemDelegate(QAbstractItemDelegate * delegate)
// Для колонки.
void setItemDelegateForColumn(int column, QAbstractItemDelegate * delegate)
// Для строки.
void setItemDelegateForRow(int row, QAbstractItemDelegate * delegate)

An example of using QAbstractItemDelegate can be found in the documentation .
