how to move the yellow buttons in keyboard controls?

[mark103]

Hi guys,

I have added the list of buttons for the channels and programs in the xbmc skin. I have one yellow box on the channel and program box for both buttons. I want to know how I can move the yellow box to go to the next program when I press on the left and right arrow buttons of the keyboard and how i can go to the next channel when I press on the up and down arrow buttons of the keyboard.

Here is the screenshot:

Here is the code:

def Channels(self):
    for row in programs:
        program = row[1].encode('ascii'), str(row[2]), str(row[3])
        title = row[1].encode('ascii')
        program_start_date = str(row[2])
        program_end_date = str(row[3])                       

        #convert the date formats into minutes
        minutes_start = self.parseDateTimeToMinutesSinceEpoch(program_start_date)
        minutes_end = self.parseDateTimeToMinutesSinceEpoch(program_end_date)
        minutes_length = minutes_end - minutes_start

        program_length = minutes_length
        program_notification = program
        programs_top = 315
        program_height = 34.5
        program_gap = 2.5
        position_start = start_pos
        position_top = programs_top + channel_index * (program_height + program_gap)


        if 10 <= program_length < 60:
            program_width = 342.5
        elif 60 <= program_length < 90:

Do you know how I can move the yellow box to go to the next program when I press on the left and right arrow buttons of the keyboard and how i can go to the next channel when I press on the up and down arrow buttons of the keyboard??

does anyone know how?

Are we supposed to know what you are talking about?

I assume that the OP is referring to XMBC Media Center, but I don't know enough about it myself to make sense out of the question, either. I would suggest that the OP seek help on the XMBC forums directly, as there presumably would be people familiar with the program in question.

I will recommend one other thing, as a general principle in Python programming. Rather than having the extended if-elif/else statement you have from lines 22-53, it would be better structured and more Pythonic to make a lookup table consisting of a range and a value. A simple representation might be a dictionary where the key is a tuple pairing the startpoint and endpoint of the length range, and the the second value is the width. You would then have a function to extract the values from the dictionary as needed. Something like this should work:

def get_program_width(program_length):
    width_map = {(10, 60): 342.5, (60, 90): 690, (90, 105) : 1050, 
                 (105, 120): 1400, (120, 150): 1750, (150, 180): 2100, 
                 (180, 210): 2450, (210, 240): 2800, (240, 270): 3150, 
                 (270, 300): 3500, (300, 330): 3850, (330, 360): 4200, 
                 (360, 390): 3250, (390, 420): 4550, (420, 450): 4900, 
                 (450, 480): 5250}

    keylist = width_map.keys()

    for key in keylist:
        if program_length in range(key[0] + 1, key[1] + 1):
            return width_map[key]
    return 0
