Hi,
an old problem is bothering me and I can't get it fixed. After double clicking a custom QGraphicsTextItem, I want to move the cursor of the QTextDocument to the position under the cursor. This is the behavior you can achieve if you press three times the mouse button. So I thought just send a mouse event, but I fail. Here my files:

Qt Code: 
  1. #include <QtGui>
  2. #include "myitem.h"
  3.  
  4. int main(int argc, char *argv[])
  5. {
  6.     QApplication a(argc, argv);
  7.  
  8.     MyItem *it = new MyItem();
  9.     it->setPlainText("String to edit");
  10.  
  12.     scene.addItem(it);
  13.  
  14.     QGraphicsView view(&scene);
  15.     view.show();
  16.  
  17.     return a.exec();
  18. }
To copy to clipboard, switch view to plain text mode 
Qt Code: 
  1. #ifndef MYITEM_H
  2. #define MYITEM_H
  3.  
  4. #include <QtGui>
  5.  
  6. class MyItem : public QGraphicsTextItem
  7. {
  8.     Q_OBJECT
  9.  
  10. public:
  11.     MyItem(QGraphicsItem *parent = 0);
  13.  
  14. protected:
  15.     void mouseDoubleClickEvent(QGraphicsSceneMouseEvent *event);
  16.     void focusOutEvent(QFocusEvent *event);
  17. };
  18.  
  19. #endif /* MYITEM_H */
To copy to clipboard, switch view to plain text mode 
Qt Code: 
  1. #include "myitem.h"
  2.  
  3. MyItem::MyItem(QGraphicsItem *parent)
  5. {
  6.     setTextInteractionFlags(Qt::LinksAccessibleByMouse);
  7. }
  8.  
  9. void MyItem::mouseDoubleClickEvent(QGraphicsSceneMouseEvent *event)
  10. {
  11.     if (textInteractionFlags() & Qt::TextEditorInteraction)
  12.     {
  13.         QGraphicsTextItem::mouseDoubleClickEvent(event);
  14.     }
  15.     else
  16.     {
  17.         setTextInteractionFlags(Qt::TextEditorInteraction);
  18.         // HERE SOME MAGIC CODE TO MOVE THE CURSOR
  19.         // which is by default at 0 after calling setTextInteractionFlags(Qt::TextEditorInteraction).
  20.     }
  21. }
  22.  
  23. void MyItem::focusOutEvent(QFocusEvent *event)
  24. {
  25.     setTextInteractionFlags(Qt::LinksAccessibleByMouse);
  26.     QGraphicsTextItem::focusOutEvent(event);
  27. }

I need to set the editor functionability only after a double click. All attempts to redirect the event leads in a total selection of the text. And creating different QMouseEvents and send them via QCoreApplication::sendEvent ended somewhere in Nirvana...

Any hints are welcome. Even code, as you know I am to lazy to do the work by my own, and it's your job to do my work...

Thanks,
