Determining if widget has children
Is there an easy way to determine if a widget--say a GTK scrolled window--has any child widgets packed into it? I've looked for a "gtk_is_parent" type function, but no luck. Any help? Thanks! Mike ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list

It should be noted however that you cannot rely on the the non-Xft rendering being available in the future. In the long run Pango will drop support for X11 core fonts.

Re: Slow Rendering?
A quick grep of the source code (gdk/x11/gdkpango-x11.c) shows that the environment variable you really want is GDK_USE_XFT, not GDK_ENABLE_XFT. I don't know whether that will make any difference to what you're seeing, but it can't hurt to try. --Brett Dennie, Brooke wrote: Hi, -Original Message- From: Sven Neumann [mailto:[EMAIL PROTECTED] Sent: Thursday, November 20, 2003 10:30 AM To: Dennie, Brooke Cc: '[EMAIL PROTECTED]' Subject: Re: Slow Rendering? Hi, Sven Neumann <[EMAIL PROTECTED]> writes: Unless you set GDK_ENABLE_XFT to 0 explicitely, you are using the PangoXft backend then. Font configuration is done using fontconfig. Please check the fontconfig user documentation at http://pdx.freedesktop.org/~fontconfig/fontconfig-user.html Sorry, I confused your answer with another thread where a user was asking for information about font configuration. Oh good, I was beginning to wonder if I'd suddenly lost my mind... The answer to your question about speed issues on remote displays is that you could try to use X11 core fonts by setting the environment variable GDK_ENABLE_XFT to 0. This would disable antialiased fonts which are likely causing your speed issues. Does your X-Server implement the RENDER extension? Hrmm. Setting the variable didn't seem to make much of a difference. The application now takes ~12s, but popups sped up to ~3s RENDER isn't implemented as far as I know since I get to see the "extension RENDER missing" error every time I run my program :D Any other ideas?

I'm never given an xfd, but rather I'm handed an XFontStruct. What I've been doing is just creating an empty font description, then calling XGetFontProperty on the XFontStruct and pulling all of the values I need for the font description out of it and filling those in. > GDK_ENABLE_XFT=0 help a little (sometimes). > For me picking a better font will help. 6.8 ms is OK, but I would > like better -> This is still 25x slower that gdk_font_load(). > Not really an option due to the nature of the project... > My GTK app runs on a linux box running Fedora Core release > 0.94 (Severn). > I am displaying on a XP computer running X-Win32 X11 server. > > Running the app directly on the linux console improves things somewhat > (ie: 6.8ms -> 4.8ms). > Also not an option... > Tony > > /- > --\ > | Tony Denault | Email: > [EMAIL PROTECTED] | > | Institute for Astronomy | Phone: > (808) 932-2378 | > | 640 North Aohoku Place |Fax: > (808) 933-0737 | > | Hilo, Hawaii 96720 | > | > \- > --/ ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list

Thanks again! Two more things that can cause long startup times are (a) not using fc-cache and (b) having extended input devices configured but not connected.
