Re: Simulating a mouse click
Thanks for the help. I was able to fix this now by setting the time member correctly. I had it set to CurrentTime before, but that didn't fix it.

Simulating a mouse click
Hi, I'm attempting to use xlib to simulate a series of mouse clicks in an application (gedit). I found some posts that describe how to do this and it essentially works. I can do left clicks on buttons and so on. But if I generate a click on the menu bar, a menu opens and something breaks and no further ButtonPress/ButtonRelease events that I send will be processed by the application. When debugging it with xtrace I noticed that my events look slightly different than real left click events.
