Qt/Embedded is modular and scalable. You can assemble the Qt features you really need and leave the others out.

Qt/Embedded includes the GUI server, client libraries, and window manager.

By picking and choosing features, the memory demands of Qt/Embedded can be tuned between 800Kb and 3 Mb in ROM (Intel x86).

Applications written with Qt have a small memory footprint compared to applications written with other toolkits due to sharing of the rich feature-set in the library.
