Filling polygons using GTK-Extra.

Hello again!

I need to draw some figures in my application that will require the 
creation and
display of polygons on the screen. On the gtkplotdata.h file I found a 
few basic
shapes like, lines, rectangles and ellipses. Is there a similar function 
for general
polygons?

I tried to fill the region defined by a set of points using 
gtk_plot_data_fill_area, but
the filling is done with respect to the x-axis... I also looked at the 
gtkplotpc.h file,
but I am not sure whether or not I could use those functions into a 
canvas widget.
I checked the CVS repository, but  couldn't find a testgtkplotpc.c file 
for some
enlightening hints either. I can try it if that's the answer, but I want 
to check with
you guys first.

Any suggestion?

    Thank you,

        Fabio.

Re: Filling polygons using GTK-Extra.

Oi Fabio! This is what I would do:

1) Take a look at gtkplotbox.[ch] copy it into a new file gtkplotpoly.[ch].
2) Replace all the Box->Poly ; plot_box -> plot_poly
3) go to gtk_plot_poly_draw_symbol, and replace all the code for dawing 
your custom polygon. Example:

 GtkPlotPoint point[n];

 point[0].x = ...;
 point[0].y = ...;
....
 point[n-1].x = ...;
 point[n-1].y = ...;

 gtk_plot_pc_draw_polygon(plot->pc, TRUE,point, n);

and voila! compile together with your code.
BTW. to convert from actual (x,y) coordinates to GtkPlotPoint (pixel) 
coordinates, you should use:

gtk_plot_get_pixel(plot, x, y, &point.x, &point.y);

Good luck!,
Saludos,

Hi Prakash! This look like a problem with the font loading, maybe a 
memory leak. However, I rewrote that piece of code completely, to use 
Pango instead of gdk fonts. Why don't you try with the new CVS version, 
and let me know?
Thanks!,

Re: Gdk-WARNING **: gdkgc-win32.c:898: SaveDC failed: Not enough

Hi Prakash,
 Your problem is with gtkplotaxis. GtkPlotAxis is now a GtkObject, so 
all the gtkplotaxis methods have a GtkPlotAxis as first argument. To 
modify an axis in a plot, you should do something like:

GtkPlotAxis *my_axis;

my_axis = gtk_plot_get_axis(plot, GTK_PLOT_AXIS_LEFT);
gtk_plot_axis_set_visible(my_axis, FALSE);
...

The API will freeze after the release, so don't worry about any changes 
hereafter.
Keep me posted, and thank you for the Makefile.
saludos,
<ADRIAN>

Memory leak in testrealtime

Hi Adrian,
 
  I have made changes as per instructions in my
application.
  I got one link error ..undefined refrence to 
 gtk_plot_canvas_add_plot(GTK_PLOT_CANVAS(canvas), gtk_plot_canvas_plot_new(GTK_PLOT(active_plot1)),
0.15, 0.01);
 
I changed above line as follows :
 gtk_plot_canvas_put_child(GTK_PLOT_CANVAS(canvas), \
 gtk_plot_canvas_plot_new(GTK_PLOT(active_plot1)),
0.15, 0.01, 0.15+.65, 0.01+.45);

Is  this correct?
 
After that change , I built my application
successfully. But during runtime, I got following
errors. Also it doesn't show plot on screen.
(Please read complete mail. Sorry for sending too
large mail :) ).

works fine, but after  25 mins it crashed.

testrealtime.exe was :

-------------------------------------------------

I don't know how to use pango font, I will read
documents related pango font & I will try it.

Thanks,

Re: Memory leak in testrealtime

Hi!
What you are doing is correct. I guss you forgot to show the widget with

gtk_widget_show(GTK_WIDGET(active_plot1));

This is not a problem with pango. All the font management API in 
gtkextra is the same, you shouldn't worry about that, since pango is in 
an inner layer invisible to the user.

Once you are able to dispplay the plots, tell me more about that memory 
leak, I can anticipate it is in gtkplotps, in the text drawing routine. 
If you can help me to pinpoint it, I will really appreciate it. Thanks a 
lot!

Keep me updated.
Saludos,
<ADRIAN>
