Ruby draw fullscreen windows


#1

Hello

Seeing the current state of “mediacenter” software, I decided to write
my own. For playing multimedia, I decided on xine-lib using
http://xiron.sourceforge.net/

I still need one thing though, something to draw windows with. Like GTK,
QT, TK, etc… Easily skinnable would be nice. It should also be easy to
control by keyboard, the goal of the GUI is that it can be used with
only four arrow keys (up, down, left, right) and an enter button. And it
should be able to draw windows fullscreen without borders. Any
suggestions?

I would also like to know if it were able to access v4l (video for
linux) devices from ruby, this thing has got to be able to make use of a
TV card.

Thanks

Glenn

I still need one thing though, something to draw windows with. Like GTK,

In the case of Ruby/Tk,

            Easily skinnable would be nice. 

Maybe, Tile extension is useful for customizable skin.

                                            It should also be easy to 

control by keyboard, the goal of the GUI is that it can be used with
only four arrow keys (up, down, left, right) and an enter button.

For example,

require ‘tk’

btag = TkBindTag.new

widgets = (0…4).collect{|y|
f = TkFrame.new.pack
(0…6).collect{|x|
b = TkButton.new(f, :text=>"(#{x},#{y})",
:command=>proc{puts “press (#{x},#{y})”},
:takefocus=>true).pack(:side=>:left)
b.bindtags_unshift(btag)
b.instance_variable_set(’@coords’, [x, y])
b
}
}

btag.bind(‘Return’, proc{|w| w.invoke}, ‘%W’)
btag.bind(‘FocusIn’, proc{|w| w.state(‘active’)}, ‘%W’)
btag.bind(‘FocusOut’, proc{|w| w.state(‘normal’)}, ‘%W’)
btag.bind(‘Left’, proc{|w|
x, y = w.instance_variable_get(’@coords’)
size = widgets[y].size
widgets[y][(x+size-1)%size].focus
}, ‘%W’)
btag.bind(‘Right’, proc{|w|
x, y = w.instance_variable_get(’@coords’)
size = widgets[y].size
widgets[y][(x+1)%size].focus
}, ‘%W’)
btag.bind(‘Up’, proc{|w|
x, y = w.instance_variable_get(’@coords’)
size = widgets.size
widgets[(y+size-1)%size][x].focus
}, ‘%W’)
btag.bind(‘Down’, proc{|w|
x, y = w.instance_variable_get(’@coords’)
size = widgets.size
widgets[(y+1)%size][x].focus
}, ‘%W’)

widgets[0][0].focus

Tk.mainloop

                                                              And it 

should be able to draw windows fullscreen without borders. Any suggestions?

For example,

requrie ‘tk’
TkButton.new(:text=>‘quit’, :command=>proc{exit}).pack
r = Tk.root
r.withdraw
r.overrideredirect = true
r.deiconify
r.geometry = “#{r.winfo_screenwidth}x#{r.winfo_screenheight}+0+0”
Tk.mainloop

On windows, “Tk.root.state = ‘zoomed’” is useful.
