I need to capture keyboard events globally (desktop environment). Must write a audio mixer application which completely replace Pulseaudio in KDE, because my corresponding professional audio interface will not correct detected by Pulseaudio. Want use Qt for the user interface for my mixer application. But need to capture the VolumeUp, VolumeDown and VolumeMute key events.
Normally I can only capture events in the Qt application itself. But exists there a Qt C++ class to capture all key events from the desktop environment without using Xlib?
There exists a similar question on SO. But the answer doesn't help.
