    So still don't understand the problem. Then add the action to e.g. a QPushButton or similar... and action can be associated to more than one widget: https://doc.qt.io/qt-5/qaction.html#associatedWidgets

      I'm not sure I understood how I can add my own QPushButton to the associatedWidgets

        Via QWidget::addActionas described in the link. But it will not help much since a QPushButton does not react on QEvent::ActionChanged - only a QToolButton or QMenu and some others do. Therefore either derive from QPushButton and do it by your own or, as I already said in my first post: 'If you want to execute an action after e.g. a button was pressed then add a button and connect the appropriate signal to the action.'

          As you said addAction() does not help with my request. It will note even trigger the associated action

            Why use a QPushButton if you want to move a QToolButton around ?

              @SGaist what are you suggesting? Is there a way I can easily insert a QAction in a layout as a QToolButton?
              If I need to create my own toolbutton, connect all the signals and icon/title changes myself, then it defeats the whole purpose of using a QAction

                Add a QToolButton to the layout and add the action with QWidget::addAction() as I already told you and the documentation tells you.

                  I have added a QToolBar in my layout, and add the actions to the toolbar, it works and I think that is the right way to do this.

                    This doesn't work. It will add a dropdown icon suggesting the toolbutton has a menu and nothing else

                      Then use signals/slots
