Hi,
I'm co-author of the app x-tile (graphical windows tiling) which is
currently in pygtk but is already fully ported to pygi (even if not public
yet).
The problem is that the pixbufs (windows icons) are rendered properly in
pygtk but are not in pygi (the icons are sometimes partially rendered,
sometimes not at all, if you click F5 to refresh the list many times you
can see it clearly).
the involved (pygtk) function is:
def get_icon(win):
""" this returns a gtk.gdk.pixbuf of the windows icon
converts argb into rgba in the process """
get_property("_NET_WM_ICON", win, glob.XA_CARDINAL)
if not glob.ret_pointer : return None
w = glob.ret_pointer[0]
h = glob.ret_pointer[1]
s = w*h
buff = ""
i = 0
while i<s:
argb = glob.ret_pointer[i+2]
i += 1
buff = buff + ("%c" % ((argb >> 16) & 0xff))
buff = buff + ("%c" % ((argb >> 8) & 0xff))
buff = buff + ("%c" % (argb & 0xff))
buff = buff + ("%c" % ((argb >> 24) & 0xff))
pxbuf = gtk.gdk.pixbuf_new_from_data(buff, gtk.gdk.COLORSPACE_RGB,
True, 8, w, h, w*4)
return pxbuf
that ported to pygi becomes:
def pixbuf_destroy_fn(pixbuf, data):
"""Function called when there are no more references of pixbuf"""
del pixbuf
def get_icon(win):
""" this returns a Gdk.pixbuf of the windows icon
converts argb into rgba in the process """
get_property("_NET_WM_ICON", win, glob.XA_CARDINAL)
if not glob.ret_pointer : return None
w = glob.ret_pointer[0]
h = glob.ret_pointer[1]
s = w*h
buff = ""
i = 0
while i<s:
argb = glob.ret_pointer[i+2]
i += 1
buff = buff + ("%c" % ((argb >> 16) & 0xff))
buff = buff + ("%c" % ((argb >> 8) & 0xff))
buff = buff + ("%c" % (argb & 0xff))
buff = buff + ("%c" % ((argb >> 24) & 0xff))
pxbuf = GdkPixbuf.Pixbuf.new_from_data(buff,
GdkPixbuf.Colorspace.RGB,
True,
8,
w,
h,
w*4,
pixbuf_destroy_fn, None)
return pxbuf
If anybody has some hints please help us.
Everybody can run the app easily from source cloning:
hg clone https://[email protected]/p/giuspen-x-tile/ hg_x-tile
cd hg_x-tile
./x-tile
and see the correct functionality
doing
hg update pygi
./x-tile
you run the pygi version, and can switch back to pygtk with
hg update default
./x-tile
Cheers,
Giuseppe.
