In my application, I am implementing status indication (displaying either 'red'
or 'green' ) by using Gdkpixmap to assign an image to 'red' or 'green' pixel
array. i display or hide the image by calling gtk_widget_show (..) or
gtk_widget_hide(..) .
The structure of my application is as follows:
int main()
{
1. Assign Pixmaps

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.
