Memory footprint is an issue, but most of it should be shared unless you plan to never ever run any other Qt app on the N900. Also, why not tackle the memory footprint? As it seems, Qt is not using a slab allocator. So even for a "simple" QString, the PIMPL and the QMetaObject are seemingly heap-allocated. Memory trashing is a real concern. Glib has been using slab allocators for ages, perhaps the time has come for Qt to use more than the Glib mainloop ;-) regards, Michael _______________________________________________ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
