Hi There,
while testing Horizon EDA on wayland using weston and sway, I found out that calls to gtk_window_present appear to have no effect. Looking at the code, it seems like this depends on the gtk_surface1 interface. Putting that into debian codesearch didn’t yield any meaningful results other than gtk itself and mutter.
Does this mean that gtk_window_present only works on GNOME/mutter and no other wayland compositors right now?

Here’s a small example based on one from Gtk that shows this problem:
//compile with gcc `pkg-config --cflags gtk+-3.0` -o example-1 present.c `pkg-config --libs gtk+-3.0`
#include <gtk/gtk.h>
GtkWidget *other_window = NULL;
static void
print_hello (GtkWidget *widget,
gpointer data)
{
g_print ("Hello World\n");
gtk_window_present_with_time(GTK_WINDOW(other_window), gtk_get_current_event_time());
}
static void
activate (GtkApplication *app,
gpointer user_data)
{
GtkWidget *window;
GtkWidget *button;
GtkWidget *button_box;
other_window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
window = gtk_application_window_new (app);
gtk_window_set_title (GTK_WINDOW (window), "Window");
gtk_window_set_default_size (GTK_WINDOW (window), 200, 200);
button_box = gtk_button_box_new (GTK_ORIENTATION_HORIZONTAL);
gtk_container_add (GTK_CONTAINER (window), button_box);
button = gtk_button_new_with_label ("Hello World");
g_signal_connect (button, "clicked", G_CALLBACK (print_hello), NULL);
gtk_container_add (GTK_CONTAINER (button_box), button);
gtk_widget_show_all (window);
}
int
main (int argc,
char **argv)
{
GtkApplication *app;
int status;
app = gtk_application_new ("org.gtk.example", G_APPLICATION_FLAGS_NONE);
g_signal_connect (app, "activate", G_CALLBACK (activate), NULL);
status = g_application_run (G_APPLICATION (app), argc, argv);
g_object_unref (app);
return status;
}
