Hover element dosen't work. Where is problem? How fix it?
Shoes.app :width => 635, :height => 410 do
background image "http://PATH_TO_IMAGE"
a = stack :width => 360, :height => 200, :margin_left => 250, :margin_top => 200 do
hover do
a.clear { para "Some Text qwe qwe qwerty", :stroke => black }
end
leave do
a.clear { background image "http://PATH_TO_IMAGE" }
end
end
end
I think in principle you cannot use image as the argument for background.
I also am not sure if that is effect you want to achieve but it shows what you did wrong:
Shoes.app :width => 635, :height => 410 do
a = stack :width => 360, :height => 200 do
image "http://PATH_TO_IMAGE"
hover do
a.clear {para "Some Text qwe qwe qwerty", :stroke => black }
end
leave do
a.clear { image "http://PATH_TO_IMAGE" }
end
end
end

Is there any way to put button(TK) on the TkCanavas widget ? I need to capture mouse button actions on diffrent parts of canavas to do a little TicTacToe game. I used TkCanavas because of drawing field lines and putting objects on exact coordinates
require 'tk'
class Window
##xs = [60,145,235,60,145,235,60,145,235]
##ys = [140,140,140,225,225,225,315,315,315] #coordinates of circles and crosses
def run
root = TkRoot.new { title 'TicTacToe' }
root.geometry("300x400+300+300")
img = TkPhotoImage.new(:file => 'cross.gif')
cv = TkCanvas.new(root)
cv.place(:height => 400, :width => 300)
cv.create(TkcImage, ##xs[2], ##ys[2], :image => img)
cv.create(TkButton, 60, 140,120,200 ) #
cv.create(TkcLine, 20, 180, 280, 180) #
cv.create(TkcLine, 20, 270, 280, 270) #Field lines
cv.create(TkcLine, 100, 100, 100, 360) #
cv.create(TkcLine, 190,100, 190, 360) #
TkcText.new(cv, 140, 30, :font => 'Arial 14',
:text => 'TicTacToe', :anchor => 'center')
Tk.mainloop
end
end
Try using TkcRectangle instead of TkButton. You can bind events to the rectangle like you can to the button.
I can't align middle a list_box in ruby shoes. I have test a few things, including :right => "50" or :left => "50", but it still not work.
Shoes.app do
stack :width => "100%", :height => "45%" do
a = list_box :items => ["lol","b"], :width => 50, :align => "center"
end
end
I did not find a direct way but you can use this hack
module Shoes::Types
def centr
left=(self.parent.width-self.style[:width])/2
self.move(left,self.top)
end
def middle
top=(self.parent.height-self.style[:height])/2
self.move(self.left,top)
end
end
Shoes.app do
#c=stack :width=>50, :height=>30 do
a=list_box :items => ["lol","b"], :width => 50, :height=>30
end
#c.centr.middle
end
What is done is actually first to extend the functionality of slots so that you can place them in the center or middle of the containing slot. Then you wrap your listbox in a tiny slot, which you center.
I am developing some prawn reports and running into an issue where any line I draw with a code like the following will render only in the last page.
horizontal_line(0, 200, :at => y)
It is called once per page.
My code is relatively complex now so I tried to isolate the problem to post here, the isolated code follows
require 'prawn'
a = Prawn::Document.new(:page_size => 'A4', :margin => [20,20,20,20])
a.font('Times-Roman')
a.horizontal_line(10, 400, :at => 140)
a.text_box('Test Text', :size => 50, :at => [2, 100], :width => 400)
puts a.render
For my surprise, it didn´t work even with a single page document. Only the "Test Text" is being rendered. It makes me think I am doing something wrong in the page setup or something like that.
Fond out the problem.
The correct use would be:
require 'prawn'
a = Prawn::Document.new(:page_size => 'A4', :margin => [20,20,20,20])
a.font('Times-Roman')
a.stroke do
a.horizontal_line(10, 400, :at => 140)
end
a.text_box('Test Text', :size => 50, :at => [2, 100], :width => 400)
puts a.render
I'm trying to layout 6 images per page with prawn in Ruby:
case (idx % 6) # ugly
when 0 : (pdf.start_new_page; pdf.image img, :position => :left, :vposition => :top, :width => 270)
when 1 : pdf.image img, :position => :right, :vposition => :top, :width => 270
when 2 : pdf.image img, :position => :left, :vposition => :center, :width => 270
when 3 : pdf.image img, :position => :right, :vposition => :center, :width => 270
when 4 : pdf.image img, :position => :left, :vposition => :bottom, :width => 270
when 5 : pdf.image img, :position => :right, :vposition => :bottom, :width => 270
end
Not sure what I'm doing wrong, but it prints the first 3 images to the PDF, then creates a new page and prints the last three:
Page 1:
<img> <img>
<blank> <blank>
<blank> <blank>
Page 2:
<blank> <blank>
<blank> <img>
<img> <img>
Any suggestions would help.
Image is going to flow (like text does) when you aren't explicitly positioning items.
Wrap each call in a float() { ... } and that will do the trick.
Alternatively, use prawn/grid for positioning.
The default vertical alignment in a flow slot is apparently to top-align the elements. Here's a sample:
Shoes.app (:title => "Vertical Alignment", :width => 300, :height => 150) do
background "#DFA"
flow :margin => 30 do
title "BIG"
tagline "MEDIUM"
inscription "SMALL"
end
end
How do I get the flow slot to center-align its elements short of calculating a :rise value for each element? I would have expected a vertical-alignment style for flow slots and a horizontal-alignment style for stack slots, but I don't see anything like that. What did I miss?
To my knowledge, there's no style for vertical alignment. There is horizontal alignment which is useful in stacks:
Shoes.app (:title => "Horizontal Alignment", :width => 300, :height => 150) do
background "#DFA"
stack :margin => 30 do
title "BIG", :align => 'center'
tagline "MEDIUM", :align => 'center'
inscription "SMALL", :align => 'center'
end
end
Keep in mind that Shoes is very much still a work in progress, so _why will probably get around to it eventually.
