Hi, I encountered a problem when using GtkPlug and GtkSocket.
I use CSS to set the background of GtkSocket to red and then use CSS to make GtkPlug transparent. I think I can see the red color because GtkPlug has been set to transparent, but it's actually black. I can't figure out why the effect is not correct. Could someone help me out? My Gtk version is Gtk 3.18. The CSS files are as follows. /* socket.css */ GtkSocket { background-color:rgba(233,23,34,1); } /* plug.css */ GtkPlug { background-color: transparent; } The code is here: [socket.c] https://pastebin.com/68XLqFUF [plug.c] https://pastebin.com/Cp3BPHFh _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
