Embedded widgets size

[Indalo]

Hello!

If I place widgets in QGraphicsView, they don't fits its size:

// Add table in the scene
	QGraphicsGridLayout *grid = new QGraphicsGridLayout();
	grid->addItem(scene->addWidget(tableWidget), 0, 0);
 
	QGraphicsProxyWidget* form = new QGraphicsProxyWidget;
	form->setLayout(grid);
	form->setCacheMode(QGraphicsItem::ItemCoordinateCache);
 
	scene->addItem(form);

// Add table in the scene
	QGraphicsGridLayout *grid = new QGraphicsGridLayout();
	grid->addItem(scene->addWidget(tableWidget), 0, 0);

	QGraphicsProxyWidget* form = new QGraphicsProxyWidget;
	form->setLayout(grid);
	form->setCacheMode(QGraphicsItem::ItemCoordinateCache);

	scene->addItem(form);

To copy to clipboard, switch view to plain text mode 

In the example above there is table in the scene, and if scene will be set to QGraphicsView, the table doesn't fit size according to the size of QGraphicsView.

That's the point. ^) Does anybody come across with such a problem?

Thanks.

Try if QGraphicsItem::ensureVisible helps you

Unfortunately, it has no effect. Either I call it with QRect or passing my QWidgetItem (which is QGraphicsProxyWidget containig QGraphicsGridLayout and QWidgetTable).

I always get:

Why would it? The item won't adjust to the size of the scene (or the view) by itself. You have to reimplement the views resizeEvent(), resize the scene and modify geometry of the item containing the layout.

wysota, thanks. Could you explain a little bit more exactly? As I got, firstly I have to reimplement QGraphicsView::resizeEvent(). There I would change size of the scene to the new size of QGraphicsView. And then...? I need to call setGeometry to every item in the scene? But how could I calculate new sizes of item? By "hand" or what?
