How to set position of a Wayland client's surface in Weston background?

问题

I create a Wayland shell surface to show "FPS info".

Now, I would like to set fixed position for this wayland client while starting the application. How can I do this ?

回答1:

Set fixed position of text displaying window by using

wl_shell_surface_set_transient (wl_shell_surface, wl_surface, POS_X, POS_Y, 0);
wl_shell_surface_set_toplevel(wl_shell_surface);
