--[[BOX WIDGET v1.1 by Wlourf 27/01/2011
This widget can drawn some boxes, even circles in your conky window
http://u-scripts.blogspot.com/2011/01/b ... .html)
Inspired by Background by londonali1010 (2009), thanks ;-)
The parameters (all optionals) are :
x - x coordinate of top-left corner of the box, default = 0 = (top-left corner of conky window)
y - y coordinate of top-left corner of the box, default = 0 = (top-left corner of conky window)
w - width of the box, default = width of the conky window
h - height of the box, default = height of the conky window
corners - corners is a table for the four corners in this order : top-left, top-right,bottom-right, bottom-left
each corner is defined in a table with a shape and a radius, available shapes are : "curve","circle","line"
example for the same shapes for all corners:
{ {"circle",10} }
example for first corner different from the three others
{ {"circle",10}, {"circle",5} }
example for top corners differents from bottom corners
{ {"circle",10}, {"circle",10}, {"line",0} }
default = { {"line",0} } i.e=no corner
operator - set the compositing operator (needs in the conkyrc : own_window_argb_visual yes)
see http://cairographics.org/operators/
available operators are :
"clear","source","over","in","out","atop","dest","dest_over","dest_in","dest_out","dest_atop","xor","add","saturate"
default = "over"
border - if border>0, the script draws only the border, like a frame, default=0
dash - if border>0 and dash>0, the border is draw with dashes, default=0
skew_x - skew box around x axis, default = 0
skew_y - skew box around y axis, default = 0
scale_x - rescale the x axis, default=1, useful for drawing elipses ...
scale_y - rescale the x axis, default=1
angle - angle of rotation of the box in degrees, default = 0
i.e. a horizontal graph
rot_x - x point of rotation's axis, default = 0,
relative to top-left corner of the box, (not the conky window)
rot_y - y point of rotation's axis, default = 0
relative to top-left corner of the box, (not the conky window)
draw_me - if set to false, box is not drawn (default = true or 1)
it can be used with a conky string, if the string returns 1, the box is drawn :
example : "${if_empty ${wireless_essid wlan0}}${else}1$endif",
linear_gradient - table with the coordinates of two points to define a linear gradient,
points are relative to top-left corner of the box, (not the conky window)
{x1,y1,x2,y2}
radial_gradient - table with the coordinates of two circle to define a radial gradient,
points are relative to top-left corner of the box, (not the conky window)
{x1,y1,r1,x2,y2,r2} (r=radius)
colour - table of colours, default = plain white {{1,0xFFFFFF,0.5}}
this table contains one or more tables with format {P,C,A}
P=position of gradient (0 = start of the gradient, 1= end of the gradient)
C=hexadecimal colour
A=alpha (opacity) of color (0=invisible,1=opacity 100%)
Examples :
for a plain color {{1,0x00FF00,0.5}}
for a gradient with two colours {{0,0x00FF00,0.5},{1,0x000033,1}} {x=80,y=150,w=100,h=20,
radial_gradient={20,20,0,20,20,20},
colour={{0.5,0xFFFFFF,1},{1,0x000000,0}},
or {{0.5,0x00FF00,1},{1,0x000033,1}} -with this one, gradient will start in the middle
for a gradient with three colours {{0,0x00FF00,0.5},{0.5,0x000033,1},{1,0x440033,1}}
and so on ...

Por incrível que pareça para alguns utilizadores, a verdade é que o Cinnamon cada vez mais está com mais utilizadores ativos. Tal como foi referido no tópico de submissões desta semana para esta Série de Ambientes de Trabalho dos Leitores do Ubuntued, está a haver uma estirpe que está a contaminar positivamente os utilizadores de tal forma que só neste artigo praticamente temos metade dos visuais com ambientes Cinnamon.
Tenho a versão do Ubuntu 10.04 e seguindo as dicas do Ubuntued instalei o conky via terminal. Quando reinicio o sistema, o conky não é exibido como mostrado nos tutoriais do site.
Existe versões diferentes do conky assim como do ubuntu?
Vitor existe versões diferentes claro, mas não se diferenciam ao ponto de serem incompatíveis.
O que está a aparecer no seu computador? Será que pode pôr esta sua dúvida no forum Ubuntued com uma imagem? Assim poderemos ter uma perceção melhor e ajudar melhor!
