Hello,
Does anyone know what would be the solution for implementing timer
support in a X11 toolkit? I already have TTimer support implemented
for LCL-CustomDrawn-Windows, Cocoa and Android (but Android is the
best tested of them), but it looks like X11 has no support for timers,
so I wonder what the best approach would be to solve this.
Roll your own event loop by calling select() on the XConnectionNumber
(which is a file descriptor). You can then use the select() timeout, or
use timerfd* functions under linux. Google around to find examples.
Also note that when doing this, you'll have to make sure you check for
all the internal connections that X opens/closes. You can do this with
XAddConnectionWatch(). The callback will give you a file descriptor
that you can add/remove to/from the set of file descriptors you a
monitoring with select().
