To use a custom widget for the final column when you select an item overload this function and return a widget. QAbstractItemView *QColumnView:: createColumn(const QModelIndex & index) Returns a list of the width of all the columns in this view. QColumnView:: ~QColumnView()ĭestroys the column view. This signal is emitted when the preview widget should be updated to provide rich information about index void QColumnView:: updatePreviewWidget(const QModelIndex & index) model takes the ownership of the item */įor more details abut Qt's Model/View Programming, please refer to the official documentation.Member Function Documentation QColumnView:: QColumnView( QWidget * parent = nullptr)Ĭonstructs a column view with a parent to represent a model's data. Here's a really simple and compilable example on how to use these classes with QColumnView: #include įor (int groupnum = 0 groupnum appendRow(child) You may rely on QStandardItem and QStandardItemModel. How can I do this? How could I add columns and rows dynamically (instead of using the QStringList like above, or any other similar method for rows)? However, I have not been able to figure out how to add more columns, and add the contact names as children of those groups in the first column. I have tried the following (based on an example from Qt Documentation): QStringList strList1 When a group in the first column is selected, the second column will show all contacts in that group, and when a contact is selected, their personal information is shown in a third column. Your contacts can belong to any of those groups. I am using Qt Creator and Qt 4 for development.Ĭonsider an address book application where you have multiple groups: Group 1, Group 2, etc. I want to display data in multiple columns in a QColumnView.
