I hadn't thought of that - alternated rows doesn't seem to work under Windows.
I'll try that.

You're completely right, of course; I figured that out a little while ago. :)
One other question: there are still white gridlines between the rows and
columns with this method. There's no easy way to get rid of those and make
each row a solid color all the way through, is there?
Cheers, K.

You don't have to set "background-set" - it's set automatically when
"background" is set.

[pygtk] TreeView - Making whole row colored, Again
Greetings,
I came across an old message in the archives at
http://www.mail-archive.com/pygtk@daa.com.au/msg15480.html , which sounds a lot
like I want to do (though I want to work with background colors rather than
foreground colors). But I was thinking: couldn't I just add a column to my
model containing the color values I want for each row, and use values of
#ff for all the rows I wanted to leave white?
The problem is that without a column of booleans, I can't seem to set the
background-set property of the columns. Specifically, I'm using:
leftjust = gtk.CellRendererText()
column = gtk.TreeViewColumn('Filename', leftjust, text=COLUMN_FILENAME)
column.set_sort_column_id(COLUMN_FILENAME)
treeview.append_column(column)
column.add_attribute(leftjust, 'background-set', True)
column.add_attribute(leftjust, 'background', COLUMN_FLAG)
but when I run the program, I keep getting
Warning: unable to set property `background-set' of type `gboolean' from value
of type `gchararray'
Is there really no way of doing this without creating another column of
booleans?
Thanks, K.

Hi,
I am trying to get a treeview (with liststore model) to display rows in

From what I've read in GTK+ 2.0 Tree View Tutorial - Tim-Philipp Muller
( c code based)
"The most suitable approach for most cases is that you add two columns
to your model, one for
the property itself (e.g. a column COL_ROW_COLOR of type G_TYPE_STRING),
and one for the boolean flag of
the property (e.g. a column COL_ROW_COLOR_SET of type G_TYPE_BOOLEAN).
You would then connect these
columns with the "foreground" and "foreground-set" properties of each
renderer. Now, whenever you set
a row’s COL_ROW_COLOR field to a colour, and set that row’s
COL_ROW_COLOR_SET field to TRUE, then
this column will be rendered in the colour of your choice. If you only
want either the default text colour or one
special other colour, you could even achieve the same thing with just
one extra model column: in this case you
could just set all renderer’s "foreground" property to whatever special
color you want, and only connect the
COL_ROW_COLOR_SET column to all renderer’s "foreground-set" property
using attributes."
Which I've implemented as attached.
The setting of foreground seems to be working (half list blue, half red)
However my implementation seems to be ignoring the foreground-set flag.
I am expecting to ONLY see my 'special' foreground color when the
modified flag is also set to true, and grey/black writing when the
foreground-set flag is False.
I can get grey writing by setting the foreground to None, but I don't
belive this was the intent of the above description.
Am I mis-understanding how this functionality should work, .. or made
some errors in my code?
Thanks for any suggestions.

Hi Steve,
I can't see the pattern in why the colors are how they are. I think
some of the trouble has to be with some 'foreground-color' set as None.
It would probably be better to not use the 'Modified' column to affect
the color, and just put the color you want the row in the
'foreground-color' column (i.e. red,black or blue) and change the
set-up to.
column.add_attribute(mycell, 'foreground', COLUMN_FOREGROUND)
mycell.set_property('foreground-set', True)
If you must stay with this set-up, this function seems to do what you want
def _cell_data_func(self, column, cell, model, iter):
(modified,foreground) =
model.get(iter,COLUMN_MODIFIED,COLUMN_FOREGROUND)
if foreground == None : foreground = 'black'
if modified :
cell.set_property('foreground',foreground)
else :
cell.set_property('foreground','black')
cell.set_property('foreground-set',True)
return False
And use "column.set_cell_data_func(mycell, self._cell_data_func)" to
set it up.
Regards Neil.

Hi Neil,
Thanks for the reply.
I'm not sure whats happening, but it's not to do with 'foreground-color'
set as None. ... I did a lot of testing before I started to introduce
None for the color.
(According to pygtk reference None is the default value of that property)
I do have a system thats working for me now, .. but I suspect it only
working because of some bug somewhere.
I totally ignore the foreground-set property, I never set it now, .. it
seems to do nothing - set or not set
If I want to change the cells color, I put it in 'foreground-color'
property, else I leave 'foreground-color' at None.
Thats it, .. it all works nicely like that. Ya, .. I know relying on
undocumented behavior is bad, .. but I needed something that works now.
Cheers
