I am a complete beginner when it comes to programming and i need some
help.
I don't know very much computer language jargan so please layman terms
as much as possible.
I began trying to learn to program about a year ago when I took my first
programming class:
1st language => Python => understood
2nd language => Java => no understanding whatsoever
3rd language => Ruby/tk => currently trying to learn, some basics
understood, but i don't understand how to use blocks and several other
huge concepts.
OBJECTIVE: create a GUI that stores browsing history in the form of Host
name, IP address, and whether nearby hosts exists (Boolean + count).
Also, the user should be able to search the storage place by either host
name or IP address to organize results.
I am currently using Unix KDevelopRuby and i am running the program via
the command line (ruby gui.rb) and i so far have:
#-------------------program
begin------------------------------------------------
#!/usr/bin/env ruby
require 'tk'
class HistBox
inst_section = {
list1 = ["All Categories","Host Name", "IP Address", "Nearby Hosts",
"Other Data of Interest"]
list2 = [10,20,30,40,50,60,70,80]
list3 = [10,20,30,40,50,60,70,80]
@var = TkVariable.new
@list2 = list2
root = TkRoot.new do
title "History"
end
# ---------------Frame----------------------
entry_frame = TkFrame.new(root) do
pack 'side' => 'top'
end
#----------Entry and DropDownMenu--------------
entry1 = TkEntry.new(entry_frame) do
pack 'side' => 'left'
end
dropMenu = TkOptionMenubutton.new(root,@var,*list3) do
pack 'side'=>'top'
end
#--------------Buttons----------------------------
button1 = TkButton.new(root) do
text "Search"
pack 'fill'=>'both', 'side' => 'top'
end
button2 = TkButton.new(root) do
text "Exit"
pack 'fill'=>'both', 'side' =>'top'
end
label = TkLabel.new(root) do
text "Search results: "
pack 'side' => 'left'
end
button1.command proc {
result = entry1.value.to_i * dropMenu.value.to_i
label.text = "The result is: #{result}"
}
button2.command { exit }
end # -------------end class---------------------
HistBox.new
Tk.mainloop
#----------------------------------------program
end--------------------------------------
as of now the program simply adds the entered value in entry1 to the
value selected from the dropdownmenu and displays the result below
following the "search results:" label.
however, i am now stuck, i would like the program to be able to talk to
the hosts visited by the user and store this info somewhere so that it
can be searched by this gui by either all categories or a specified
category (change pull down menu to reflect list1) .
Also, i would like to produce the results in some sort frame following
the Search results label, and i think it would be helpful to display the
results in treeView unless anyone can think of a better idea.
TreeView example:
···
___________________________
Search results:
+ www.google.com |
> + www.yahoo.com |
> - www.aol.com |
> - Host Name |
> - AOL |
> - IP Address |
> - 999.999.9.9 |
> -Other Args |
> - info |
>___________________________|
So, yeah i hope that gives you guys a pretty good idea of what i'm
trying to do so hopefully you might be able to help me. Any advice is
very much appriciated as i continue to guess and check my work :-/.
thank you for your time.
