Great! Thank you :)
The last question is, when i find correct callback signature, passed 
arguments absolutely cannot be modified in any way, including adding 
random arguments, right?

My favorite tool for desoldering is a hot air blower.  It may look
like a glorified hair dryer, but it works like a charm.  No damaged
tips either :-)

Maybe, he just needs a friendly reminder to actually do as indicated.

gEDA-user: Soldering tips

2011-03-09 Thread Darryl Gibson 
The other day I wanted to salvage some parts off a dead TV chassis,
but I didn't want to
use my good soldering tip to do so.

I had some solid 12 gauge house wire laying around, so I gave it a
try. I stripped a six inch
piece, folded it over on itself, and twisted it up like twisted pair
wire. It threaded into my
Weller SP23 iron, trimmed it to length, and it worked like a charm.

Now, if I can fashion a "tip" out of it, I may never buy another
commercial tip again?

The success story would look like:

1) Look up the function ghid_button_connected()
2) the function creates a GtkButton b and calls:

if (cb_func)
gtk_signal_connect (GTK_OBJECT (b), "clicked",
GTK_SIGNAL_FUNC (cb_func), data);

3) Hence you look up signal "clicked" in GtkButton
http://library.gnome.org/devel/gtk/unstable/GtkButton.html#GtkButton-clicked

4) There you find correct callback signature:

void user_function (GtkButton *button,
gpointer   user_data);

Mark, many thanks for posting the references to that conversation.
I appreciate the very appropriate and poignant subject line mentioning
“DRY, colon cancer, and redundant, repetitive redundancy”. :-)
My thoughts exactly.

The “ugly workaround” [1] you mention is exactly what I described as
Option 2. (Except I use the convention of the normal input-2 symbol,
using the ‘value’ attribute instead of ‘description’.)

There is also a post-processing kludge [2] implementing Hidden option 3!
This solves all the original problems but does bring its own
inconveniences because it's implemented with post-processing scripting.

Regards,
Colin

Hi!

On Thu, 03 Mar 2011 15:39:22 +0100, Krzysztof Kościuszkiewicz wrote:

> I was asking why in the model you keep strings and not ints/floats?

I don't know if i can directly place user-editable numeric values into 
treeview, instead of strings, it's possible? This is due to absence of 
examples: all treeview's C code samples found (with user-editing) are 
text/string. But also it's due to probably in future, user input can be 
in form '50 mil' or '2e3 mkm', i don't know useful it or no, but 
currently it can be easy added.

> custom implementation of GtkTreeModel ...

It can work only in my dreams, because currently i even don't know how to 
write gtk callback procedure header...:(
Example:
I need to write "Set by Mark Distance" button press procedure (as you 
see, currently tied to dummy write (and it work well :D ) )
I copypaste your new cb_edited_mm_or_mil proc, because *it has access to 
treeview items* and contains all i need; only small modifications need.
I don't touch the header because i don't know how to rewrite it correctly:
/(GtkCellRendererText *cell,
  gchar *path,
  gchar *text,
  GtkTreeView *treeview)/
but it tied not here
/  g_signal_connect(renderer, "edited", (GCallback) cb_edited_mm_or_mil, 
treeview);/
but i place it here :
/  ghid_button_connected (hbox_btn_grids, NULL, FALSE, FALSE, FALSE, 4, 
  cb_grid_setbymarkdistance, NULL, _("Set by Mark Distance"),  ../
and it of course not work: program crashes silently, no any debug info, 
no way to read anything or things how to rewrite the header, no suitable 
examples... compiles without warnings.

Is there any success-story about it or example using docs IRL ?

Can your netlister output a netlist for gEDA-PCB?
