QPlainTextEdit in a QGraphicsView

wejgomi

Hi,

I am trying to embed a movable code editor into a QGraphicsView.

Currently I am able to embed a QPlainTextEdit into a QGraphicsView. I use QGraphicsProxyWidget and also set QPlainTextEdit `s parent as another QGraphicsWidget item.

   QGraphicsWidget* parentWidget = new QGraphicsWidget();
  parentWidget->setMinimumSize(QSizeF(100, 30));
  parentWidget->setFlags(QGraphicsItem::ItemIsMovable);
  parentWidget->setAutoFillBackground(true);
  scene->addItem(parentWidget);

 editor = new QPlainTextEdit(); 
 QGraphicsProxyWidget *proxy = scene->addWidget( editor);
 proxy->setParentItem(parentWidget);
 proxy->setWidget(editor);
 proxy->setPos(5, 5);
 proxy->setFlags(QGraphicsItem::ItemIsMovable|QGraphicsItem::ItemIsSelectable|QGraphicsItem::ItemSendsGeometryChanges |
                        QGraphicsItem::ItemSendsScenePositionChanges);

This helps me to render the QPlainTextEdit object in QGraphicsView. It also receives mouse events and it is movable since its QGraphicsWidget parent is movable.

The problem is QPlainTextEdit object does not receive keyboard events. How can I achieve this by using this setup ?

If I can not , which one would be the better alternative ?

a) Implementing a code editor from QGraphicsTextItem
b) Rendering QPlainTextEdit on top of QGraphicsWidget and making it movable

Thanks in advance

Hi,

Looks like you are missing the QGraphicsItem::ItemIsFocusable flag.
