Determining if widget has children

[Mike Dailey]

Is there an easy way to determine if a widget--say a
GTK scrolled window--has any child widgets packed into
it?

I've looked for a "gtk_is_parent" type function, but
no luck.

Any help?  Thanks!

Tim:

Thank you!  That works beautifully!  My app looks MUCH
better now with a little color!

Thanks a million!

Now if I can figure out how to add space between
columns, my data won't look so bunched up.

Thanks,

Mike Dailey

It is possible, just not particularly obvious.  What
you need to do is 
call gtk_tree_view_column_set_widget, passing in your
own label that is 
set to display the column title.  Once the label is
shown and realized, 
call gtk_widget_get_parent three times, which should
move up through a 
GtkAlignment and a GtkHBox to give you a GtkButton. 
This button is the 
column header.  Calling gtk_widget_modify_bg on it
will change the 
background colour of the column header.

TreeView Functionality Questions

[Mike Dailey]

A few questions regarding TreeViews (yes, I read the
FAQs and API documentation)...

Is it possible to add spacing between TreeView
columns?

Is it possible to add a verticle line/seperator
between columns?


Thanks!

GTK TreeView Column Header Colors

[Mike Dailey]

Is it possible to change the foreground and background
color of the column header in a GTK TreeView, using a
ListStore as the model?

I found that I can successfully pack a widget (say, a
button with a label) into the column header, and
change the colors of this button/label widget, but it
just doesn't look right since the button does not
expand to fill the entire column header cell.  

Is there an easier way to do this?  As always, any
help is greatly appreciated, and some example code
would be a miracle! :-)

Thanks,

Mike
