QT 4.4 QGraphicsProxyWidget bridge Drag and Drop help

[patrik08]

What do you mean "forward drag and drop"? Does the view accept drops?

i not think that QGraphicsView must send all drag and drop event to his subitem?
but it works ...
i hope to not forward keyPressEvent and all other ...

void XhtmlView::dragEnterEvent ( QDragEnterEvent * e )
{
	/* DivDiagram *CurrentActive; only xhtml <div>  tag */
	if (CurrentActive->id() > 0 && CurrentActive->ProxyBridgeEdit->isVisible()) {
		CurrentActive->AdvanceEdit->wtxt->insertFromMimeData(e->mimeData());
		return;
	}
}

void XhtmlView::dragEnterEvent ( QDragEnterEvent * e )
{
	/* DivDiagram *CurrentActive; only xhtml <div>  tag */
	if (CurrentActive->id() > 0 && CurrentActive->ProxyBridgeEdit->isVisible()) {
		CurrentActive->AdvanceEdit->wtxt->insertFromMimeData(e->mimeData());
		return;
	}
}

Yes ... but i like only drag drop on subitem QGraphicsProxyWidget an his QWidget
the doc say : QGraphicsProxyWidget imo forum QTCLASS 4.4beta not found http://doc.trolltech.com/main-snapsh...oxywidget.html

The QGraphicsProxyWidget class provides a proxy layer for embedding a QWidget in a QGraphicsScene.
QGraphicsProxyWidget embeds any QWidget-based widget, for example, a QPushButton, QFontComboBox, or even QFileDialog, into QGraphicsScene. It forwards events between the two objects and translates between QWidget's integer-based geometry and QGraphicsWidget's qreal-based geometry. QGraphicsProxyWidget supports all core features of QWidget, including tab focus, keyboard input, Drag & Drop, and popups. You can also embed complex widgets, e.g., widgets with subwidgets.
QGraphicsProxyWidget takes care of automatically embedding popup children of embedded widgets through creating a child proxy for each popup. This means that when an embedded QComboBox shows its popup list, a new QGraphicsProxyWidget is created automatically, embedding the popup, and positioning it correctly.

I wand to build only a xhtml editor that processing div tag floating absolute and display it block or not...

It could be D&D related event passing through the proxy has not yet been implemented. We are talking about beta software here.

you know another way to display inside QGraphicsView / QGraphicsTextItem an exdended
xhtml editor? not beta?

Implement a custom QGraphicsItem.

Now is running i drag drop from QGraphicsView and send to QGraphicsTextItem proxie..
to insert image or so..
And QGraphicsTextItem become 33 line to handle text from parent QAction on a simple way..

void DivDiagram::TextHandler()
{
    QColor col;
    QAction *invoice = qobject_cast<QAction *>(sender());
    const double cases = invoice->data().toDouble();
    QTextCursor c = QGraphicsTextItem::textCursor();
    QTextCharFormat format = c.charFormat();
    QFont f = format.font();
    if (cases == 0.01) {
    f.setBold(true); 
    } else if (cases == 0.02) {
    f.setItalic(true); 
    } else if (cases == 0.03) {
    f.setOverline(true); 
    } else if (cases == 0.04) {
    f.setUnderline(true); 
    } else if (cases == 0.05) {
    f.setStrikeOut(true); 
    } else if (cases == 0.06) {
        col = QColorDialog::getRgba();
        if (!col.isValid()) {
        return;
        }
    format.setForeground(QBrush(col));
    } else if (cases == 0.07) {
        col = QColorDialog::getRgba();
        if (!col.isValid()) {
        return;
        }
    format.setBackground(QBrush(col));
    } else if (cases > 3) {
    f.setPointSizeF(cases); 
    } else {
    return;
    }
    format.setFont(f);
    c.setCharFormat(format);
}

void DivDiagram::TextHandler()
{
    QColor col;
    QAction *invoice = qobject_cast<QAction *>(sender());
    const double cases = invoice->data().toDouble();
    QTextCursor c = QGraphicsTextItem::textCursor();
    QTextCharFormat format = c.charFormat();
    QFont f = format.font();
    if (cases == 0.01) {
    f.setBold(true); 
    } else if (cases == 0.02) {
    f.setItalic(true); 
    } else if (cases == 0.03) {

        col = QColorDialog::getRgba();
        if (!col.isValid()) {
        return;
        }
    format.setForeground(QBrush(col));
    } else if (cases == 0.07) {
        col = QColorDialog::getRgba();
        if (!col.isValid()) {
        return;
        }
    format.setBackground(QBrush(col));
    } else if (cases > 3) {
    f.setPointSizeF(cases); 
    } else {
    return;
    }
    format.setFont(f);
    c.setCharFormat(format);
}
