Simulate keyboard events on Linux
High level GUI Library/Framework(like QT, GTK+) make it easier to develop GUI programs in Linux. But both of them are lack of some features because their design purpose.So it seems, I have no thing to do unless programming with Xlib if i want to to simulate keyboard events.Fortunately, I got XTest(the X test extension), a library to test X11 server without user intervention, which can be used to simulate mouse and keyboard events in three ways.
