Showing message on status bar

There's an empty space below app.title that we can
use as a status bar. So, I modify this recipe and
make it into a module. (need fgimage.pyd from here)



# status.py

from graphics import *

import fgimage

__all__ = ["status_on", "status_off"]



bar = Image.new((119,13))

bgcolor = screenshot().getpixel((0,0))[0]

fg = fgimage.FGImage()



def status_on(message=None):

    if message is not None:

        bar.clear(bgcolor)

        bar.text((0,11), unicode(message), 0xffffff)

    fg.set(57,30, bar._bitmapapi())



def status_off():

    fg.unset()

You can use it easily this way



>>> from status import *

>>> status_on('Hello world')  # show it

>>> status_off()              # hide it

>>>

See a screenshot.

Using foreground image

You can draw directly to the phone screen.
It is useful for a notification from a background program.
You need to install fgimage.pyd from here.



import fgimage, e32



img = Image.new((100, 16))  # create a notification text

img.text((0, 14), u'Hello world', 0)



fg = fgimage.FGImage()

x, y = 0, 40           # position to draw

fg.set(x, y, img._bitmapapi())  # send it



e32.ao_sleep(1)

fg.unset()                # then clear it
