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.
Presumably with the usual health warnings on whether select() updates
its parameters. As far as I could tell when hacking serial.pp, Linux
does but Solaris (8, 10) doesn't.
Indeed. It seems like relying on this is not a good idea. So then
using timer_create with pselect is probably the most portable approach.
