Hi
It's possible to change the background color of the Topwindow?
This is a piece of my code

screen = TopWindow.TopWindow()
screen.background_color = 0xff0000

This change the color of the corner but not the color background.

It works for me. Here is what I tried (almost identical to the wiki article):

import TopWindow
from graphics import *
import appuifw
import e32
 
height = 29
width = 130
top = 59
left = 110
window = TopWindow.TopWindow()
image = Image.new((width,height))
window.add_image(image, (width,height))
#If only width and height are specified, the image will not be resized.
#In order to resize the image the final coordinates must be specified as well:
#window.add_image(image, (width,height,x2,y2))
window.size = (width, height)
window.corner_type = 'square'
window.position = (left,top)
window.background_color = 0xffa130
 
def exit():
	window.hide()
	app_lock.signal()
 
app_lock = e32.Ao_lock()
window.show()
 
appuifw.app.exit_key_handler = exit
app_lock.wait()

This displays a light-blue rectangle. I don't understand why yours wouldn't work.

Looking at your code, I noticed that this piece of code was in the wrong position:

screen.add_image(img, (5,5,174,45))

I put the after this piece of code and therefore did not work:

window.size = (width, height)
window.corner_type = 'square'
window.position = (left,top)
window.background_color = 0xffa130

If i add this code to try the topwindow he does not work:

def topwindow():
	height = 29
	width = 130
	top = 59
	left = 30
	window = TopWindow.TopWindow()
	image = Image.new((width,height))
	window.add_image(image, (width,height))
	#If only width and height are specified, the image will not be resized.
	#In order to resize the image the final coordinates must be specified as well:
	#window.add_image(image, (width,height,x2,y2))
	window.size = (width, height)
	window.corner_type = 'square'
	window.position = (left,top)
	window.background_color = 0xffa130
        window.show()

appuifw.app.menu = [(u"Top",topwindow)]

The code Bogdan gives is to change the colour of the window.

window.background_color = 0xffa130

Do you mean to change the window colour or the Background colour of the window?

You will have to work on native extensions for the latter.

The code of bogdan.galiceanu works fine, but if i put him into a function does not work.
The topwindow does not appear.

Thats because you have deployed a menu.

Try to implement this with a selection list.

def top():
	height = 29
	width = 130
	top = 59
	left = 30
	window = TopWindow.TopWindow()
	image = Image.new((width,height))
	window.add_image(image, (width,height))
	#If only width and height are specified, the image will not be resized.
	#In order to resize the image the final coordinates must be specified as well:
	#window.add_image(image, (width,height,x2,y2))
	window.size = (width, height)
	window.corner_type = 'square'
	window.position = (left,top)
	window.background_color = 0xffa130
              window.show()

L = [u'Top']
# create the selection list
index = appuifw.selection_list(choices=L , search_field=1)

# use the result of the selection to trigger some action (here we just print something)

if index == 0:
	top()

I've added this line and now works fine!

image.clear(background)

[ikaroweb80]

I'm try this code:

def top():
	height = 29
	width = 130
	top = 59
	left = 30
	window = TopWindow.TopWindow()
	image = Image.new((width,height))
	window.add_image(image, (width,height))
	#If only width and height are specified, the image will not be resized.
	#In order to resize the image the final coordinates must be specified as well:
	#window.add_image(image, (width,height,x2,y2))
	window.size = (width, height)
	window.corner_type = 'square'
	window.position = (left,top)
	window.background_color = 0xffa130
              window.show()

L = [u'Top']
# create the selection list
index = appuifw.selection_list(choices=L , search_field=1)

# use the result of the selection to trigger some action (here we just print something)

if index == 0:
	top()

I've a rgb color and the window.background_color accept only hex color, how can convert rgb to hex?

I've tried with this code:

r = color[0]
g = color[1]
b = color[2]
border = "%02X%02X%02X" % (r, g, b)
border = "0x" + border 
screen.background_color = eval(bordo)

But the color that showed it's different from the rgb value.

border = "0x" + border

But the color that showed it's different from the rgb value.

I've searched the net and found this algorithm:

def tohex(r,g,b):
	hexchars="0123456789ABCDEF"
	return "0x"+hexchars[r/16]+hexchars[r%16]+hexchars[g/16]+hexchars[g%16]+hexchars[b/16]+hexchars[b%16]

[ikaroweb80]

Now i've this error:

Exception:  an integer is required

[bogdan.galiceanu]

In what line do you get that error? If it was in the function I provided, here is an example of how to use it:

>>>print tohex(12,230,73)
0x0CE649

[ikaroweb80]

hexchars="0123456789ABCDEF"
bord = "0x"+hexchars[r/16]+hexchars[r%16]+hexchars[g/16]+hexchars[g%16]+hexchars[b/16]+hexchars[b%16]
screen.background_color = bord

My rgb color
rgb color=153 255 0

The hex color converted
hex color= 0x99FF00

I've tried with this code:

rgb = r+g+b
screen.background_color = rgb

But the color showed it's different from the rgb color.

[ikaroweb80]

I've this hex color returned from the function tohex, but when i try to set background.color with this hex he give this error:

>>> 0xFF33FF
Exception:  an integer is required

screen.background_color = bord

The error means exactly what it says: "Exception: an integer is required". The result of conversion is a text string, not a number. You need to convert it to number beforehands.

The code from bogdan.galiceanu was correct, but you seem to have skipped over one part:

window.background_color = eval(bord)
