It wouldn't matter too much, since most screens would only have a
refresh rate of 60-120 Hz, which is also much higher than what most
people can even see.
I've handled such cases by using g_idle_add when I get an update of the
variable's status, and have the idle function update the text box. I
preserve the event source ID for the next call, and check if that source
is still available. If so, I remove the event using g_source_remove and
add a new idle event. This way, the most recent update is shown on
screen the next time my program goes idle. The idle function then marks
the source as free, by setting it to zero.

Subject: Continuous variable updation in a text box
Date: Tue, 10 Mar 2009 02:48:15 -0700 (PDT)
I intend to monitor the variable's value (acquired via data acquisition
hardware) at a rate of around 1,000 times per second.
I haven't used textboxes before in GTK+. Could anyone suggest how to update the
value of a variable in a textbox etc., at this rate.
Thanks,
Adeel
