gtkdialog again (sorry) – How to use variables inside gtkdialog?

[Johnny Rosenberg]

I just can't figure it out. I saw an example (I think) but now I can't find it:
Let's say that I have three combo boxes in a dialogue:

blah blah

<comboboxentry>
    blah blah
    <variable>y</variable>
    blah blah
</comboboxentry>

<comboboxentry>
    blah blah
    <variable>x</variable>
    blah blah
</comboboxentry>

<comboboxentry>
    blah blah
    <variable>z</variable>
    blah blah
</comboboxentry>

Then I have an editable text box:
<edit>
    blah blah
    <variable>Text</variable>
    blah blah
</edit>

And finally an add button:
<button label="Add">
    blah blah
</button>

blah blah

What I want to do is to select some combo box entries and click the
add button. A new line should then be added to the editable text box,
for instance (expressed in bash syntax):
Text="${Text}\n${x}: ${y} – ${z}"

I have tried the most obvious things, but nothing made me happy so far…

I figured out how to copy the text (if I enter it manually directly to
the box) to a file using the <output file> tag, but not how to get the
text INTO the box without typing it manually…

Sorry for bothering so much the last few days.
