Re: DGSEAL_ENABLE: replace direct addressing in statusbar
Oh, woops, just glanced at the documentation, well, I guess you could leave it with the ->label for now, and once 3.0 comes, switch over as both the method and GSEAL stuff will be in place at that point. You could always write the code for the transition now and add a preprocessor check like so: #if GLIB_CHECK_VERSION(3, 0, 0) // new code which gets the box's child #else // old code you pasted in the mail #endif On Sun, 04 Jul 2010 06:57:48 +0100 Carlos Pereira wrote: > On 07/04/10 06:17, Nader Morshed wrote: > > statusbar = gtk_statusbar_new (); > > label = gtk_statusbar_get_message_area (GTK_STATUSBAR (statusbar)); > > gtk_misc_set_alignment (GTK_MISC (label), 0.5, 0.5); > > > Thanks Nader, I believe you are in the right path (although the > documentation actually says this returns a box, not a label): > > http://library.gnome.org/devel/gtk/stable/GtkStatusbar.html#gtk-statusbar-get-message-area > > Anyway this has been added in Gtk 2.20, I am still running 2.18.3, lots > of users also, it might be better to wait... > > Thanks! > Carlos > ___ > gtk-app-devel-list mailing list > gtk-app-devel-list@gnome.org > http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list -- Nader Morshed ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Re: DGSEAL_ENABLE: replace direct addressing in statusbar
I believe you'd want to use gtk_statusbar_get_message_area: statusbar = gtk_statusbar_new (); label = gtk_statusbar_get_message_area (GTK_STATUSBAR (statusbar)); gtk_misc_set_alignment (GTK_MISC (label), 0.5, 0.5); On Sun, 04 Jul 2010 06:09:09 +0100 Carlos Pereira wrote: > Hi, > How can I rewrite the following code, to be GTK 3.0 ready (without > addressing directly the label, forbidden by the -DGSEAL_ENABLE mechanism)? > > statusbar = gtk_statusbar_new (); > gtk_misc_set_alignment (GTK_MISC (GTK_STATUSBAR (statusbar)->label), > 0.5, 0.5); > > Cheers, > Carlos > ___ > gtk-app-devel-list mailing list > gtk-app-devel-list@gnome.org > http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list -- Nader Morshed ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
DGSEAL_ENABLE: replace direct addressing in statusbar
Hi, How can I rewrite the following code, to be GTK 3.0 ready (without addressing directly the label, forbidden by the -DGSEAL_ENABLE mechanism)? statusbar = gtk_statusbar_new (); gtk_misc_set_alignment (GTK_MISC (GTK_STATUSBAR (statusbar)->label), 0.5, 0.5); Cheers, Carlos ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

The Scribble project has two source files (scribble.c and scribble-xinput.c). Further investigation reveals that they actually compile to two different executables (At first, I thought they were both part of the same project which would have been worrying - because scribble.c needs gtk-2.0, whereas scribble-xinput.c needs gtk-1.2). ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

It uses some gdk types (e.g. GdkDeviceInfo) which seem to be missing from gtk-2.0 but which look as though they used to be present in gtk-1.2. I guess I could temporarily rename my gtk-2.0 include folders to make gtk-2.0 inaccessible to the compiler but I'm curious to know if there's a better way to revert to the older version?

They are offscreen drawables and, on most systems, are very quick because the GPU can move them about. You'd link to the configure event to build the offscreen pixmap.
