Hi;
I am trying to plot radar data using gtk+. I have started from scratch and
this is my first attempt at gtk+. My problem is:
I am using the following code to plot the target on the window.
gdk_color_alloc(gdk_colormap_get_system(), &color);
gdk_gc_set_foreground(gc,&color);
gdk_draw_arc(pix, gc,true,p->x,p->y,4,4,0,360*64);
But I would like to place an object instead of the point(target) so that the
object moves when I change the x and y position of the object. Right now the
previous point remains on the screen even after I plot a new point on the
screen. Basically I would like to move the point around the screen so that
only one point is visible at a time. If someone could send me a code for
creation of objects or icons which can be moved around the screen unlike a
point which is retained on the screen. Another problem with the point is
that once I minimize the screen the point is rubbed off. Can anyone tell me
how to create objects at run time and move them on the screen? My email id

Thanks
