QM
6.2.3
Model-Based Design Tool
The QM™ Modeling Tool uses the Qt Toolkit↑ under the terms of the GNU Lesser General Public License v. 3 and the GNU Lesser General Public License v. 2.1 (both jointly "LGPL"↑). In compliance with LGPL, this document collects the relevant information about downloading, installing, and building the Qt Toolkit from sources. The main source of the information and most of the web links provided here come from the Qt Company's↑ website.
The first step in compliance with LGPL is that every recipient of the QM software receives also the full text of the LGPL licenses used. QM complies with this requirement by including the full text of the LGPL licenses (lgpl-2.1.txt and lgpl-3.txt) in every QM distribution. The full text of the LGPL licenses can also be obtained in this QM documentation by clicking on the links below:
On each supported platform (Windows, Linux, and macOS), the QM™ Modeling Tool dynamically links to the unmodified Qt libraries, as provided by the Qt Company↑ in the pre-compiled binary format.
Also, in compliance with LGPL, the "About QM" dialog box of the QM application prominently states that this program uses the Qt Toolkit under the terms of LGPL.
Additionally, the QM Help Menu includes the standard "About Qt" dialog box, which informs the user about the exact version of Qt and explains the Qt licensing terms. Finally, the QM Manual prominently states that this program uses the Qt Toolkit under the terms of LGPL.
The QM Modeling tool has used several Qt versions. Please choose the Qt version displayed by the QM "About Qt Dialog Box":
