Re: Urgent regarding resizing of boxs

[Roland Bock <box2OO6 eudoxos de>]

Hi Nisha,

attached is a small sample program that essentially reproduces the 
problem. I marked the line which you need to change.

Hope this helps.

And please, for further questions of this kind, reduce the problematic 
code to the bare minimum and/or send something that compiles!

Here are some guidelines from the top of my head that would help 
reviewing your code:

a) Unless your problem can be described by less than say 10 lines of 
code, send something that can be compiled and linked.

b) Remove ALL unnecessary complexity.
For instance in the code you sent, there is a loop for 6 databoxes and 6 
seperators. One box would have been enough. Since you sent the mail to 
non-gtkdatabox-users, too, you should have considered replacing the 
gtkdatabox widget by a standard widget. You also call factory functions, 
make_box, labelBoxFunc, and 
gtk_databox_create_box_with_scrollbars_and_rulers. Users of GtkDatabox 
don't know two of those, others don't know all three.

d) Use variables with intuitive names.
You are using box_main, HBox_main, hbox1, hbox2, hbox3, vbox1, vbox2, 
vbox3 as containers which are used in a counterintuitive order (for my 
brain). Its too many of them and their names do not tell enough of their 
purpose. Before sending code for inspection by others, review it for 
ease of understanding.


These guidelines are certainly neither perfect nor complete, but please 
try to stick to them!

If you do,

*) many of your problems will be solved by yourself during the 
preparation of the question

*) questions are more likely to be answered quickly

*) the quality of your code will increase


Since this is the 10th or so question about packing widgets, you might 
also want to take a look at a tutorial for this topic, e.g.
http://library.gnome.org/devel/gtk-tutorial/stable/c355.html

Regards,

Roland
