Get and Install Qt

You can get Qt, its modules and tools via Qt Online Installer or Qt Maintenance Tool.

Via Qt Online Installer you can do new installations. Qt Maintenance Tool is included in each Qt installation and with it you can update your Qt installation for example by adding and removing components.

You can use Qt Online Installer and Qt Maintenance Tool via a graphical user interface or a command line interface. The command line interface enables installing and uninstalling without any user interaction, that is, unattended usage.
