Re: changing colour of widget

["Vest V." <vest 84 gmail com>]

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
