Qt currently does not have the capabilities to detect if a key is pressed... the same does not have the capabilities I need.
So I had to use native code:

#ifdef Q_OS_WIN #include "Windows.h" #endif ... bool MyTableView::edit(const QModelIndex & index, EditTrigger trigger, QEvent * ev) { if (trigger == AnyKeyPressed) { #ifdef Q_OS_WIN HKL lang_id = GetKeyboardLayout(0); // get the current keyboard layout unsigned short prim_lang = LOBYTE(lang_id); //take only the primary language identifier switch (bytes.toInt()) { case 0x04: //Chinese case 0x11: //Japanese /* maybe other future languages that use special input methods */ //clear current content, then the editor will be open with pinyin activated QKeyEvent* toSend = new QKeyEvent(QEvent::KeyPress, Qt::Key_Delete, Qt::NoModifier); return QAbstractItemView::edit(index, trigger, toSend); } #endif } return QAbstractItemView::edit (index, trigger, ev); }
