This patch makes Sculpt's leitzentrale GUI able to respond to touch events. It formerly assumed that click/clack events are always preceded by hover reports that identify the clicked-on widgets. For touch events, however, the most up-to-date hover information referred to the previous click because there is no motion without touching. So the GUI tended to identify the wrong widgets as click targets. The patch solved this problem by testing the freshness of the hover information at the time of the click. If the hover information is older than the click, the action is deferred until up-to-date hover information becomes available. Fixes #4398
This directory is a source-code repository containing Genode-specific services and applications. In contrast to the components that come with the 'os' repository, programs contained in 'gems' are able to leverage the functionalities provided by higher-level repositories such as 'libports'. To use the 'gems' repository, make sure to also add those repositories to your build configuraion.
