Rename file use virtual Keyboard in the QTableView

  • hello, every one!
    I use the QFileSystemModel show files in the QTableView, and now I need to rename the file via the virtual keyboard.

    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, but the editor is closed too.
    I refer to the following link, but I do not know how to handle -- QApplication::postEvent(lineEdit, evt);
    My code as follows:
    void UI_FileManage::slot_editRename()
    if(false == tableView_view->currentIndex().isValid())
