About GtkCurve

[dupont durand <neojecee_spam_trash yahoo fr>]

Hi,

 

I'm writing a simple application to display some data using a GtkCurve.

 

A loop is running in a separate thread and gets information given by an external counter, in order to draw a curve on screen using a GtkCurve object.

 

The loop looks like :

[...]

gtk_curve_set_range( my_curve, x_min, x_max, y_min, y_max );

 

while( condition )

{

   [ ... ]

   /* vector : points to display */

   gtk_curve_set_vector( my_curve, vector_length, vector )

   gtk_curve_set_curve_type( my_curve, GTK_CURVE_TYPE_FREE )

}

 

 

In fact I have some refresh problems. Considering T is current time, gtk_curve_set_vector displays vector(T) two or three times consecutively, whereas it should display vector(T+1) and then vector(T+2) (both values are different from vector(T)  ) ...

It doesn't seem to be a thread synchronization problem. Any idea ?

 

Furthermore, does anyone know where can I find some examples or documentation linked to this GTK object ?

 

Many Thanks !

 

Jecee
