Запрос в гугл spy++ linux Первые 3 ссылки: один два три Найденные программы: xclients to list the programs that have a connection to a display xprop to display window properties xwininfo to display technical information about a window (position, visuals, …) There are also tools to manipulate X resources: appres, editres (for those few applications that implement it), listres, xrdb. For Qt, a quick search turns up Qt Inspector, inspired by KSpy, a tool hidden in the KDE repositories. Run the application under xtrace. It'll log all communications between the application and the X server, including the command to send or receive an X client message. xtrace myapp Command xev -id WINDOW_ID will print X11 "window events". In X11, these things are called "events". (As opposed to "messages" in Microsoft Windows). To obtain window id, use xwininfo. man xev, man xwininfo. I've seen a "spy" feature from Squish. This is a GUI testing tool. WinFormSpy provides some of the basic features provided by Spy++ for winform applications running using mono.
