Thanks for your help.
I have been looking at the GTK code (gtkcurve.c and 
gtkcurve.h) and I think I could find out where the problem
is and fixed it. I have just made a copy of the object 
called "gtk_my_curve" and correct it. I send you attached 
at this message the code just in case some of you wants to 
know whatï¿½s up and/or use it. Fortunately, the solution was 
very simple (it is commented on the gtk_my_curve.c file).
I have used this code and seems to be OK.
Am I to send it to the GTK developer team...???
Most cordially.

Hi all:

I am using the gtk_gamma_curve Widget and each time I

run

my program I get the following error:

Glib-Error: Could not allocate -20 bytes

I get also the same error that I get using the

gtk_curve

(instead of the gamma) and attempting to change the

curve

type (using the gtk_curve_change_type) to

GTK_CURVE_LINEAR.


I know that gtk_curve and gtk_gamma_curve are not

Widgets

widely used, but anyway may be most handy for my

purpouses.

Any help on this will be most appreciated.

Yes, this is a known problem with GtkCurve. In fact I
removed the Type
property in recent versions of Glade to avoid it.

There may be a way to work around the problem, e.g. by
making sure you
set a certain vector of points before changing the curve
type. But I'm
not sure.

Damon
