QTableWidget Delegate

[aekilic]

I have just figure out someting,

Please try, create a qtablewidget with 3 row and 3 columns. When you come to 3rd row and 3 column if you double click into the cell and press tab after that you will go the 1st row and 1st column the curser will go like editing the cell, I had to avoid that? How could I do it?

But I wasnt able to get the message for tab2

I see you are using an event filter. On which widget did you install it?

Were you able to what I am doing?

Please check the attach, please see the 1.jpg after that when I press tab, 2.jpg occurs. What I want is in the 1.jpg when I press tab I want the curser to go on the 0,0 cell but not editing mode like picture 3 mode.

You may try providing your own item delegate that will not emit the default closeEditor() signal but will instead emit it with QAbstractItemDelegate::NoHint. See the docs for details.

Open Assistant and type in "closeEditor" in the index tab.

Dear All

What i did is blow

QWidget *CekSenetDelegate::createEditor(QWidget *parent,
           const QStyleOptionViewItem &option,
           const QModelIndex &index) const {
 
			QComboBox *editor = new QComboBox(parent);
 
			editor->addItem(QString::fromUtf8(""), "0");
			while(...) editor->addItem(...);
			editor->setSizeAdjustPolicy(QComboBox::AdjustToContents);
 		        connect(editor, SIGNAL(editingFinished()), this, SLOT(commitAndCloseEditor()));
 
			return editor;
}
 
 void CekSenetDelegate::commitAndCloseEditor()
 {
		QMessageBox::warning(0, QString::fromUtf8("zzzz"),
		QString::fromUtf8("İzzzz"));
 
		QComboBox *editor = qobject_cast<QComboBox *>(sender());
		    emit commitData(editor);
		    emit closeEditor(editor, QAbstractItemDelegate::NoHint);
 
 }

QWidget *CekSenetDelegate::createEditor(QWidget *parent,
           const QStyleOptionViewItem &option,
           const QModelIndex &index) const {

			QComboBox *editor = new QComboBox(parent);

			editor->addItem(QString::fromUtf8(""), "0");
			while(...) editor->addItem(...);
			editor->setSizeAdjustPolicy(QComboBox::AdjustToContents);
 		        connect(editor, SIGNAL(editingFinished()), this, SLOT(commitAndCloseEditor()));

			return editor;
}

 void CekSenetDelegate::commitAndCloseEditor()
 {
		QMessageBox::warning(0, QString::fromUtf8("zzzz"),
		QString::fromUtf8("İzzzz"));

		QComboBox *editor = qobject_cast<QComboBox *>(sender());
		    emit commitData(editor);
		    emit closeEditor(editor, QAbstractItemDelegate::NoHint);

 }

To copy to clipboard, switch view to plain text mode 

I never get the message zzzz

I don;t see where you set

...
editor->setEditable(true);
...

...
editor->setEditable(true);
...

at first. then QComboBox has not such signal editingFinished, but QLineEdit has.
so, you should write like this:

QWidget *CekSenetDelegate::createEditor(QWidget *parent,
           const QStyleOptionViewItem &option,
           const QModelIndex &index) const {
 
            QComboBox *editor = new QComboBox(parent);
            editor->setEditable(true);
            editor->addItem(QString::fromUtf8(""), "0");
            while(...) editor->addItem(...);
            editor->setSizeAdjustPolicy(QComboBox::AdjustToContents);
            connect(editor->lineEdit(), SIGNAL(editingFinished()), this, SLOT(commitAndCloseEditor()));
 
            return editor;
}

QWidget *CekSenetDelegate::createEditor(QWidget *parent,
           const QStyleOptionViewItem &option,
           const QModelIndex &index) const {
 
            QComboBox *editor = new QComboBox(parent);
            editor->setEditable(true);
            editor->addItem(QString::fromUtf8(""), "0");
            while(...) editor->addItem(...);
            editor->setSizeAdjustPolicy(QComboBox::AdjustToContents);
            connect(editor->lineEdit(), SIGNAL(editingFinished()), this, SLOT(commitAndCloseEditor()));
 
            return editor;
}
