For various reasons I want to initialize
a pixmap (GdkPixmap*) to something besides NULL.
Is there another quick and easy thing I can
initialize pixmap object too?
(There is a command to return a pointer to
a new pixmap object but I did not understand
the first arg.)
Thanks,
Chris

Examples of expose and configure event functions
regarding pixmaps seem to return either TRUE or FALSE.
What is the meaning of this return value and the purpose?

Examples of configure and expose event functions
have a mysterious GtkWidget for the first arg.
I cannot seem to discern what it is.
Please explain...
Here is an example of an expose event function:
gint middleMassTimeSeriesPlotPatch(GtkWidget* widget, GdkEventExpose* event) {
Is it possible to have gtk_label_new(TEXT)
be vertical or rotated???
Since one cannot put letters in a pixmap this
is my only hope for vertical/sideways letters.
Thanks,

Hi all,
I have this graph that is to show the traffic throughput. It updates every
2 secs. What should be the correct way to do this so that the axes can
update dynamically, i.e it progress from right to left, showing the time.
The diagram below shows the x-axis.

Thank you.
I was just thinking what would be the best way of action.
Have the function registered on a button pressed event, and removed on a butto
n realeased event?
or have a gtlobal static variable set to TRUE, and the function registered on
a button press, and have the button release set

Thanks for reply. So it sounds like some signal handlers
are only the first of many functions to handle an event.
(Most of which we don't see or deal with?)
If our function does ALL work then we return TRUE
but if it is only one of many then we return FALSE.

This widget that is the first argument seems to be the window

no. its the widget for which the event took place and for which the

confusion.
I'm confused because some
value_changed events are when someone changes
value with a slider bar. (I think.)
This calls a signal handler that gets the GtkAdjustment
object as a parameter. How/where can I pull out the value
that slider bar value was changed to. I need to do
something with the NEW value!
Thanks,
