Thanks, I don't know why I didn't change that, because I know the
difference. I guess I just didn't think…
Anyway, so far, so good, but the next step is to keep the dialogue in
a separate file, like this (file name stored in
${DialogFolder}/musician-dialogue.xml – I know it's not a real xml,
but I call it that to make gedit view tags and data in different
colours – better ideas are appreciated):
<vbox>
    <hbox>
        <text>
            <label>Instrument:</label>
        </text>
        <comboboxentry>
            <default>Välj musikinstrument</default>
            <variable>Instrument</variable>
            <input file>$InstrumentsList</input>
        </comboboxentry>
            <text>
                <label>Utövare:</label>
            </text>
        <comboboxentry>
            <default>Välj utövare</default>
            <variable>Musician</variable>
            <input file>$MusiciansList</input>
        </comboboxentry>
    </hbox>
    <hbox>
        <button ok></button>
        <button cancel></button>
    </hbox>
</vbox>

Now, in the script, I have the following lines:
# Code starts here
-------------------------------------------------------------------
#!/bin/bash

RosenTagDir="${HOME}/bin/RosenTagg"
InstrumentsList="${RosenTagDir}/Lists/Instruments"
MusiciansList="${RosenTagDir}/Lists/Musicians"
DialogFolder="${RosenTagDir}/Dialogues"

export MainDialog=$(<${DialogFolder}/musician-dialogue.xml)
gtkdialog --program MainDialog
# End of code -------------------------------------------------------------------------

Now I end up with the same problem again; the Bash variables do not expand.
I tried a few different combinations of double quotes on the export
MainDialog=$(<${DialogFolder}/musician-dialogue.xml) line with no
luck.


Well, at least it works now, but it would be so nice if I could have a
separate file for the dialogue.
Thanks!
