The structure of my code is that when I click on the 'start button', the callback function needs to continuously acquire data from a daq card in a while loop, a functionality that I am not supposed to change. Now I want to send a refesh signal to control (during the course of button callback function) and one way to do this it to call a g_timer_add function which my current gtk_installation (gtk 1.2.10) doesn't support.

So, don't try to make main loop runs faster than it is. maybe you should send a refresh (or repaint, update) signal to your control. what do you think ab. it? 2009/5/11 Adeel Malik <adeelmali...@yahoo.com>: > Hi, > The main gtk thread needs to refresh an image widget (for status > indication, GREEN or RED) along with a couple of 'status variables' > e.g Block/Symbol error rate using labels.
