Hi i’m in a programming a class and i’m doing an assignment i’ve gotten
it to work but one of the entries is messed up it takes the place of a
diffrent one
Here’s the code
require ‘gtk2’
window = Gtk::Window.new
window.border_width = 10
window.title = “Future Value Investment Calculator”
window.resize(450,200)
convertButton = Gtk::Button.new(“Convert”)
closeButton = Gtk::Button.new(“Close”)
oink = Gtk::Image.new(Gdk::Pixbuf.new(“piggybank.gif”, 150, 200))
promptLabel = Gtk::Label.new(“Enter amount invested in U.S Dollars:”)
tempEntry = Gtk::Entry.new
promptLabel2 = Gtk::Label.new(“Enter Rate of return as a decimal(e.g.
enter 8% as .08):”)
tempEntry2 = Gtk::Entry.new
promptLabel3 = Gtk::Label.new(“Enter number of years the money will be
invested:”)
tempEntry3 = Gtk::Entry.new
resultLabel = Gtk::Label.new("")
vbox1 = Gtk::VBox.new(false, 0)
hbox1 = Gtk::HBox.new(false, 0)
hbox2 = Gtk::HBox.new(false, 0)
hbox1.pack_start(convertButton, true, false)
hbox1.pack_start(closeButton, true, false)
vbox1.pack_start(promptLabel, true, true)
vbox1.pack_start(tempEntry, true, true)
vbox1.pack_start(promptLabel2, true, true)
vbox1.pack_start(tempEntry2, true, true)
vbox1.pack_start(promptLabel3, true, true)
vbox1.pack_start(tempEntry3, true, true)
vbox1.pack_start(resultLabel, true, true)
vbox1.pack_start(hbox1, true, true)
hbox2.pack_start(vbox1, true, true)
hbox2.pack_start(oink, true, true)
window.add(hbox2)
window.show_all
convertButton.signal_connect(“clicked”) {
dollars = tempEntry.text.to_f
rate = tempEntry.text.to_f
time = tempEntry.text.to_i
fv = dollars*(1+rate)**time
output= " In " + time.to_s + " years your investment will be worth " +
fv.to_s
resultLabel.set_label( output )
}
closeButton.signal_connect(“clicked”) {
Gtk.main_quit
}
window.signal_connect(“destroy”) {
Gtk.main_quit
}
Gtk.main
if u could help i would really appreciate it
