Bug 210603 – [GTK][X11] REGRESSION(r259944): Wrong position of select popup menu in X11

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Carlos Garcia Campos]

It works in Wayland, but fails in X11.

Does anybody know how to make gdk_window_move_to_rect() work in X11? It seems we need to convert the coordinates somehow, but I don't know exactly how. gtk_window_move() works fine in X11, so if I can't make gdk_window_move_to_rect() work for both I'll use it only under wayland.

Jonas says: "i don't understand the question. that API is used internally in gtk by both wayland and x11"

I learned a Finnish proverb from Adrian: "the reindeer will go where the fence is the lowest." The reindeer are wise....

Maybe the long-term solution for this is using GtkPopover[Menu],
like I just did for bug #170553 — then we can let GTK do the
positioning work using gtk_popover_set_pointing_to(widget, rect)
and gtk_popover_set_position(widget, GTK_POS_BOTTOM) to make the
popover appear below the button. If we want to remove the arrow
that would point to the button or change the appearance I *think*
there are some CSS classes we can set. As for making the popover
width at least as long as the button, I think *maybe* we could
use a GtkSizeGroup, but maybe if we end up using a popover there
is not much point in doing that 🤔️

Yup.
