the art of packing

[Mark Mackenzie <markm student unsw edu au>]

Hi,

I was hoping to get some advice (or some further url's) about the art
of packing. I have read the tutorial section on packing a few times,
and have been playing around with glade which is so good, it makes 
widgeting trivial (I did try some unaided to get a feel for it though).

Some questions in particular:
i) Is it a 'bad thing' to set x &| y widths of various widgets if I
am having trouble getting them to behave as I expect them?

ii) I would like:

                  +------------+
+frm--+   Label   |  but.text  |
| rb1 |           +------------+    +------------+
| rb2 |                             |  but.text  |
+-----+           +------------+    +------------+
          Label   |  but.text  |
                  +------------+

So I have:

+window
      `vbox
        +hbox1 (a box above box of interest)
        +hbox2
        | +frame1 (vbox with 2 radio buttons)
        | +table1
        | | +label1 "Input file: " (Added " " for alignment. Is this ok?)
        | | +label2 "Output file:"
        | | +button1
        | | `button2
        | `vbox2   (oops - is this the right way to do it?)
        |   `button3
        `hbox3 (another box below box of interest)

Am I on the right track? 

Is vbox2 superfluous?

Buttons1&2 will bring up file dialog boxen and the label will be
changed to the selected filename(without path). Is it ok to set
horizontal width?

Thankyou for any input.
Mark.
