The post in the site referenced in the comment above got updated:
Thanks, I tried putting wl_proxy_marshal((struct wl_proxy *) xdg_surface,
XDG_SURFACE_ACK_CONFIGURE, serial); (xdg_surface_ack_configure() equivalent)
before every vkQueueSubmit (I know that you meant to put the ack in response to
events, but while trying to make things work, I thought that it needed to be
before every vkQueueSubmit), and the window-menu started working, but events
weren't triggering. I then discovered that I needed to call
wl_display_roundtrip() every frame and only call xdg_surface_ack_configure
after certain events (xdg_surface_listener's and xdg_toplevel_listener's
configure events (not the xdg_surface_listener's event is always present when
configure events happen (and is always the last event according to
xdg-shell.xml), so ack_configure only needs to be put in xdg_surface_listener's
configure event)). This is what I ended-up with in my draw loop:
retStatus = wl_display_flush(display);
if(retStatus == -1) {
//TODO: use poll() to wait until display fd is writable
again, and call wl_display_flush again
exit(1);
}
wl_display_roundtrip(display); //blocks
submitInfos[0].pCommandBuffers = &commandBuffers[imageIndex];
vkQueueSubmit(graphicsQueue, 1, submitInfos,
fence);
wl_display_dispatch_pending(display);
