[python] New Window From Main Window?

[safetycopy]

Hi,

I'm new to Python and PyGTK/GTK+ development, but I've managed pretty well so far. I'm working on a little GUI to explore various (old and simple) encryption algorithms.

I started with the screenshot below, but what I'd like to do is take the range widget out and move it to a new window that would pop up on clicking an 'options' button that I'll add next to the 'Encrypt' button.

I know how to do various kinds of dialogs, but can't find any info on spawning a new window from the main window.

Also, do I need to know anything in particular about retrieving the values from widgets in a new window, or can I do it in the same way as I'm doing from my main window?

Anyway, here's the screenshot:

Make another class that has the new window and show it when you click on the right button.

class Popup(object):
def __init__(self):
self.window = gtk.Window()
self.window.show_all()

And then have your main window do something like this:

popup = Popup()

Okey doke - will give that a try!

Should I store an instance of the new class in the main class, or just create an instance of the new class when the button's clicked?

Also, how would I pass, say, range values from the range signal handler back to the main application?

I have this to start my application off:


if __name__ == "__main__":
l = Lucipher()
l.main()

So can the new class's signal handler set properties of the 'l' instance?

your main class can have a variable that you can set to equal the popup windows range value.In the popup class have a callback to set a variable
with the current range value.Make sure it starts with "self." so that you
can access it like this
popup.range_value.

The range widget is on the popup right?

The range widget is on the popup right?

Yeah, the range will be in the pop-up 'options' window.

I think I get what you're saying, so I'll go play around a bit.

Thanks for your time! :-)
