Hi,
The code for the little tool to inspect theme colors is now available
from
http://gist.github.com/49799
The blog post [2] has also been updated accordingly.

Re: [pygtk] changing the foreground colour of entry box dynamically
The documentation shows that there are five states for a widget[1].
For each state, the GTK theme defines different colours for
background, foreground etc.
You can see some discussion about colours on John Stowers blog[2]. He
has a good screenshot showing the different colours for each state[3],
which makes it easier to find which colour you want to change.
You can directly modify the bg, fg, text, and base colours using the
widget.modify_* functions. For example:
mywidget.modify_bg(gtk.STATE_NORMAL, mycolor)
# if you have a widget which changes appears when
# selected you might have to change the other states as well.
mywidget.modify_bg(gtk.STATE_SELECTED, mycolor)
Here is what I found about the theme guidelines for different colours[4]:
# fg - Sets the foreground color of a widget.
# bg - Sets the background color of a widget.
# text - Sets the foreground color for widgets that have editable text.
# base - Sets the background color for widgets that have editable text.
I only have experience changing the colours for my own custom widgets
which do not to have states like prelight or selected. Let me know if
this works.

In case you need to change the background too, i tryed to use modify_bg with
no luck while modify_base just works. I have not understood which is the
difference between one and the other, not I could find an explanation
of the difference between modify_bg and modify_text. The second works to
modify the text of an entry, the first does not.
Any one can explain or pint to documentaion on the difference between
base/bg and text/fg?
In the kiwi package there is an interesting validation field that uses also
images as background. I wanted to do the same but didn't manage missing a
simpler example...

Well, that's what I get for not even checking the documentation before
posting. I forgot the first argument to 'modify_text' should be a state
value. The relevant states here are:
- gtk.STATE_NORMAL for unselected text
- gtk.STATE_SELECTED for selected text when the entry is focused
- gtk.STATE_ACTIVE for selected text when a different widget is focused

I haven't tested this, but the method 'modify_text' should do what you
need. For example, to set the text to red, use:
entry.modify_text(gtk.gdk.color_parse('red'))
and to set it back to the default black:
entry.modify_text(None)

Re: [pygtk] changing the foreground colour of entry box dynamically
Hi, Take a look at Kiwi's entry widget - it makes that stuff easy. The Kiwi page is here: http://async.com.br/projects/kiwi/ The docs for the entry widget is here: http://async.com.br/projects/kiwi/api/kiwi.ui.widgets.entry.ProxyEntry.html Hope this helps.
