How to use Person class in model in Qt MVC

[tokafr]

Hello!

I have such task. I want to display information(including image) about person on button.
I have QAbstractTable model to set these buttons with that information. I created my own person class
and give the constructor parameters(name, lastName, date of birth, and path to image);
I created getter and setter methods to handle this data. so now I want to use this class in my model.
In the model class I have a QList<Person*>. So the problem is that model methods work with QVariant data type and I cannot get the Person object in the Delegate class. How can I fix it?

Thank you!

Hi,

You have to use "Q_DECLARE_METATYPE":http://doc.qt.io/qt-5/qmetatype.html#Q_DECLARE_METATYPE to register your custom type then you can use it through QVariant.

By the way, are you sure that you need a QList<Person *> and not just a QList<Person> ?

I have implemented the same with something like the following. I have implemented PersonModel class with following information.

@class PersonModel : public QAbstractTableModel
{
Q_OBJECT
QList<Person> mydata;@

Using QModelIndex with appropriate row/column and role information you should be able to fetch the data.

thank you all, Q_DECLARE_METATYPE works fine.
