open web page from Ruby Tk app

e deleflie

All,

I'm trying to avoid using TkHTML (too many dependencies in a
cross-platform app).

I just want to click on a "link" (maybe a TkLabel with text underlined
and in blue) ... and open a URL in a web page.

- Does anyone have some sample code for opening a web page in the OS's
default browser?
- also, does anyone have any sample code on executing a proc on mouse
down in a TKlabel?

any help is appreciated.

Etienne

require 'tk'

def on_button_press(e)
widget = e.widget
xcoord = e.x
ycoord = e.y

puts "button pressed, x:#{xcoord}, y:#{ycoord}"
end



root = TkRoot.new {
title 'Label Test'
geometry "600x400+200+50"
}

label = TkLabel.new(root) do
text "click me"
pack
end

label.bind('ButtonPress-1', lambda {|e| on_button_press(e)})
label.bind("ButtonRelease-1", proc{puts "button released"})

Tk.mainloop

Where did you learn that?

An interesting thing happens when we line up our
fossil finds according to how old they are.
We can see how life changed through time.

I'm on your side by I do wish you would quote so we know
to what you are replying and format your lines to a reasonable
length.
