/**
* @brief Create a QInputDialog. This must be called in MainWindow thread because Widgets must be created in the GUI thread.
* Here an exemple how to call it:
*
* bool sameThread = QThread::currentThread() == qApp->thread();
* Gui_InputDialogReturn ret;
* qRegisterMetaType<Gui_InputDialogReturn>("Gui_InputDialogReturn");
* QMetaObject::invokeMethod( MainWindow::getInstance()
* , "guiInputDialog"
* , sameThread ? Qt::DirectConnection : Qt::BlockingQueuedConnection
* , Q_RETURN_ARG(Gui_InputDialogReturn, ret)
* , Q_ARG(QString, windowTitle)
* , Q_ARG(QString, labelText)
* , Q_ARG(QLineEdit::EchoMode, textEchoMode)
* , Q_ARG(bool, modal)
* );
*
* @param windowTitle: the window title (caption).
* @param labelText: label's text which describes what needs to be input.
* @param textEchoMode: the echo mode for the text value.
* @param modal: pop up the dialog as modal or modeless.
* @return Gui_InputDialogReturn ( Accepted(1)|Rejected(0), text value for the input dialog)
