2.10) and I think GIO is not supported in this version

Hello Mahesh,

It depends on which approach you want to use: draw LEDs manually, or
display images. The first possible widget is GtkDrawingArea:
https://developer.gnome.org/gtk3/3.2/GtkDrawingArea.html,the second is
GtkImage: https://developer.gnome.org/gtk3/3.2/GtkImage.html

Regarding the event: probably you need GIO library (especially the
GFileMonitor: https://developer.gnome.org/gio/unstable/GFileMonitor.html)

Kind regards,
Vlad

 Hi List,

 I went through basics of GTK searching for any widget that could represent

 Also, is it possible to generate an event whenever file is updated instead
 of user (mouse clicks, keyboard press)


 Any Help

Hello Mahesh,

I did not know that you use the old version. Actually, Gnome VFS is
deprecated, but on your Linux it should be still available. This library
has a similar monitor:
https://developer.gnome.org/gnome-vfs/stable/gnome-vfs-2.0-gnome-vfs-monitor.htmlProbably,
this should suit you the most.
There is also another library that you can try to use:
http://en.wikipedia.org/wiki/Inotify
If you do not want to add additional libraries (I assume there are more
solutions like proposed above), you can write a custom function to get
information about the file in the main loop or in a separate thread. If the
information, such as changed date and size, changes, you can send a custom
event.

Kind regards,
Vlad
