      thanks for replying back
      and thank you,

      i saw the example on the qt documentation about the address books, and i liked it but,
      my program is some sort of school management
      in the center of it there is tabs of different functionalities
      inside those tabs i want my data which is a mysql data to get displayed to the user
      like picture,first names,last names and so
      what is the best thing i can do about this idea
      thanks again <3

          @the_owler said in how to add pictures to a qt widget table in qt:

          creating a web site

          Well, there are many many possibilities/frameworks and this is out of Qt scope (even if you could use Qt to create a web page).
          "and getting it inside a web widget" - do you mean you want to render a web page in your app? If so take a look at https://doc.qt.io/qt-5/qtwebengine-index.html

            @jsulm
            i give you the general approach and tell me what to do
            i have created a full c++ console app
            which is a school management console app
            with c++ connector(with mysql)
            then i get in with the qt to have the desktop app
            but am getting a lot of difficulties in learning and implementing things inside the mainwindow and getting a good design as i want
            so i decided maybe to create a website then implement it inside my app
            what do you recommend
            and thanx for replying,
            and sorry for the long text

              Well, user management systems are often coupled with web technologies.

              Is it your case ?

              As for getting data into widget, QDataWidgetMapper comes to mind.

                  QDataWidgetMapper does the link between widgets and database fields.

                  How are you storing images in that database ?

                        sorry for late xD 600 second cooldown
                        @SGaist u mean by fixed is that a single format ? like png or jpg ?
                        if so no it wwill be just one format
                        and its controlable by the user

                        *its a desktop app that is controlable by just one user so the format type is not an issue

                          Will you use a QTableView ? If so you can either use a custom QIdentityProxyModel that will create a QPixmap from the blob for the DecorationRole or a custom QStyledItemDelegate to draw the blob.

                              It depends on how you want your user to access the data.

                                  This looks like a classic web application.

                                  While you can do the front end with Qt, I think you should first rethink your backend architecture to provide all the services needed to manage such an application.
