Hi Robert,
Will Qt be an integral part of application development on genode or is it just there for legacy support?
in the foreseeable future, Qt will be the best way to go for developing GUI applications for Genode. We are not planning otherwise. In a recent posting on the l4-hackers mailing list, I mentioned my principal interest in following up my past work with the DOpE GUI server at some point in the future. But this is not a tangible plan right now (more of a day dream).

If you decide to go for porting Qt5 to Genode, your work will be well received. The perfect way to start is to open a new topic on our issue tracker. There we can discuss the best way to go forward:

Once the issue is opened, I am sure that others that have a stake in the topic will get involved.
Cheers Norman
