Hi,

Am doing a project in c with gtk.
can anyone there help me on

how to load a file into gtk window.
like a html file on the disk into a window tt we can get by clicking a button ?
and is there an way to load time changing ( adding ) files like log files to load into a gtk window or using a c program ???
