Move the Center of QwtPlot to specific coordinates

[alexge233]

Hello,

I've created a class that inherits from QwtPlot, and then added a slot connected to a signal caught at mouse drag/move events:

class UI : public QwtPlot
{
  public:
 
    UI ( )  : ...
    {
       ...
       _pickerMachine = std::make_shared<QwtPickerDragPointMachine>();
        _picker->setStateMachine( _pickerMachine.get() );
        connect( _picker.get(), SIGNAL ( moved ( QPoint ) ), this, SLOT ( callback ( QPoint ) ) );
       ...
    }
 
  public slots:
 
    void callback ( QPoint point )
    {
        std::cout << "move callback to: " << point.x() << "," << point.y() << std::endl;
    }
 
  private:
    ...
}

class UI : public QwtPlot
{
  public:
 
    UI ( )  : ...
    {
       ...
       _pickerMachine = std::make_shared<QwtPickerDragPointMachine>();
        _picker->setStateMachine( _pickerMachine.get() );
        connect( _picker.get(), SIGNAL ( moved ( QPoint ) ), this, SLOT ( callback ( QPoint ) ) );
       ...
    }

  public slots:

    void callback ( QPoint point )
    {
        std::cout << "move callback to: " << point.x() << "," << point.y() << std::endl;
    }

  private:
    ...
}

To copy to clipboard, switch view to plain text mode 

I understand that I can ask for a replot, although I'm not sure how. Been searching for a few hours but couldn't find much info.
My callback does get signaled the position of the mouse click, how can I move the plot to use as center the QPoint where the mouse click occured?
