[Solved] QTableView Edit with one click

sharethl

I have to use inputMethod for input, no hardware keyboard.
But there is a problem,
Although I set all triggers to QTableView, one click did get cell in edit and can see the blinking cursor, virtual keyboard still not showing up.
I have to click the editor again, then virtual keyboard could show up.
Why is this? and I tried Delegates no helps. (Change to LineEdit, and post mouse click event to it, doesn't work either.)

// working with combobox.
void DisplayPolicyItemDelegate::setEditorData(QWidget *editor, const QModelIndex &index) const
{
    Q_UNUSED(index);
    QComboBox *comboBox = qobject_cast<QComboBox*>(editor);
    if(comboBox==0) return;
    comboBox->showPopup();
}

PS: virtual keyboard could show up on line edit that is not in TableView.

Solved by pass event release. Not pressed.

    QMouseEvent* evt = new QMouseEvent(QEvent::MouseButtonRelease,
                                       QPointF(1,1), // Cannot use lineEdit->width()/2 somehow.
                                       Qt::LeftButton,
                                       Qt::LeftButton,
                                       Qt::NoModifier);
    QApplication::postEvent(lineEdit, evt);

Hi, I have a same question with you now.I used your method in the delegate, but it did not work. Can you help me with the details?
My code is as follows：
QWidget* createEditor(QWidget parent, const QStyleOptionViewItem & option,const QModelIndex & index) const
{
Q_UNUSED(option);
Q_UNUSED(index);
QLineEdit lineEdit = new QLineEdit(parent);
connect(lineEdit,SIGNAL(textChanged(QString)),this,SLOT(slotPrivate_editorChanged(QString)));
lineEdit->setMaxLength(_nameLength);
QMouseEvent* evt = new QMouseEvent(QEvent::MouseButtonRelease, QPoint(1,1),Qt::LeftButton, Qt::LeftButton,Qt::NoModifier);
QApplication::postEvent(lineEdit, evt);
return lineEdit;
}
