An unexpected journey

Software

Since my last post quite some progress has been made in getting KWin working on top of a Wayland compositor. My main focus of work has been on the input stack. This is something I am not really familiar with as so far we did not have to care about it.

As some might know input handling in X11 is very insecure. Every application is able to listen to every key event. And in the KDE workspaces we obviously make use of these “features”. For example the global shortcut handling is implemented as a kded module listening to all key events and notifying the application via D-Bus that the shortcut got triggered. In a post-X11 world this will not work any more: applications are no longer able to listen to all key events.

One of the important tasks therefore is to not send all input events to the X-Server but just to the window which should get it, or to handle the input events inside KWin and discard them without passing to the applications.

    The number of open source applications and tools that are available on today’s popular operating systems is simply mind-blowing. They come in all forms. Small scripts and console tools that can be easily integrated into large projects, feature-rich applications that offer everything a complete solution, well designed tools, games that encourage real participation, and eye catching candy. Open source software holds many compelling advantages over proprietary software. Open source improves the quality of the code, keeps costs down, encourages innovation and collaboration, combined with superior security, freedom, flexibility, interoperability, business agility, and much more.
