With them I've been able to change the color of the basic Sugar display, and
to create boxes of differing colors.
Several major issues remain (which may not be surmountable?):
1) when text displayed on the basic screen (in no box) - that area reverts
to gray;
2) importantly, nothing else displays in my colored boxes; this includes
frames, other boxes, text and buttons.
Can you guide me toward solutions here?
I'm basically modifying Lazzarini's csndsugui.py. Here is the revised box
code:
def box(self, vert=True, colour=(0x, 0x, 0x), parent=None,
padding=5):
creates a box
vert: True, creates a vertical box; horiz.
otherwise
parent: parent box, None if this is a toplevel box
padding: box padding
returns the widget instance
if vert:
box = gtk.VBox()
else:
box = gtk.HBox()
self.event_box = gtk.EventBox()
self.event_box.modify_bg(gtk.STATE_NORMAL, gtk.gdk.Color(colour[0],
colour[1], colour[2], 0))
if parent:
parent.pack_start(self.event_box)
else:
self.outbox.pack_start(self.event_box)
self.window.set_canvas(self.outbox)
self.boxes.append(box)
self.event_box.show()
box.show()
return box
I suspect that chaages in the last few lines are required (especially in the
boxes line and probably the packing).
And here is the current text code. I rather imagine if this could be
gotten to display in a box with the box retaining its color, I might be on
the way to success (but this may be the hard part; can other things be
displayed over an event_box?). This code is straight from Lazzarini:
def text(self, name, box=None,colour=(0,0,0)):
Creates a static text label
name: text label
box: parent box, None if text is to be placed toplevel
colour: RGB values in a tuple (R,G,B)
returns the widget instance
label = gtk.Label(name)
label.modify_fg(gtk.STATE_NORMAL,
gtk.gdk.Color(colour[0],colour[1],colour[2], 0))
if box:
box.pack_start(label, False, False, 5)
else:
self.outbox.pack_start(label, False, False, 5)
label.show()
return label
I very much appreciate your help. I, too, wonder if all this hassling over
color is worth it. If only there were some simple way to make the overall
display white instead of gray! I'm wanting the color change strictly for
readability; I need more color contrast to read the text (which is
unfortunately profuse in my project).

Forgot to mention the PyGTK FAQ, which has several entries related
about changing background colors:
http://faq.pygtk.org/index.py?req=index
I don't think any of the issues you are referring to are specific to
Sugar, so you can use the upstream documentation without fear of
missing any details.

Re: [Sugar-devel] Background Screen Color for SoaS Activity
Tomeu and Gary, Thanks for your advice and interest. I've attached my complete activity (OurMusic) in the form of an .xo archive. Note that it requires csndsugui.py (included), Victor Lazzarini's Csound GUI toolkit. It's barely possible that the color issue lies therein (but unlikely). The background color issue is the only issue when the activity is run on OLPC; on SoaS, there is another as well: an unavailable csnd or _csnd module (from python 2.6). For the latter issue, Aleksey suggested a Scons-related fix (that I've yet to be able to implement, unfortunately, as my technical expertise is *highly* limited). If you manage to get an initial display on a white background, I'd be most grateful. If you do have/get a display, probably options 2 and 4 will work for you; they use only the ASCII keyboard, no MIDI controllers (unlike 1 and 3). I'd be delighted if these worked on SoaS. Gary, I'll be trying your code as well. I presume it should go near the beginning in my main loop? (Sorry, my grasp of both python and GTK -- OOP for that matter -- is so minimal.)
