Re: Memory leak in testrealtime

Hi!
What you are doing is correct. I guss you forgot to show the widget with

gtk_widget_show(GTK_WIDGET(active_plot1));

This is not a problem with pango. All the font management API in 
gtkextra is the same, you shouldn't worry about that, since pango is in 
an inner layer invisible to the user.

Once you are able to dispplay the plots, tell me more about that memory 
leak, I can anticipate it is in gtkplotps, in the text drawing routine. 
If you can help me to pinpoint it, I will really appreciate it. Thanks a 
lot!

Keep me updated.
Saludos,
<ADRIAN>
