Hi folks,

I want to be able to put up a file-picker dialog box from Lua.

Something like this:

function dialog_ttload()
    file_picker_new_dialog("My Plugin Load and Filter",
do_load_and_filter, "File to load", "Filter String")

register_menu("My Plugin Load & Filter", dialog_ttload, MENU_TOOLS_UNSORTED)

And then have the callback do interesting things, like pre-filter
through tshark or talk to a special hardware device or whatever.

In any event, it allows a plugin to put up a file picker dialog box.

It turns out that it is not hard to do. Please see the attached.

However, I am sure I have not thought of all the necessary things and
maybe it needs to be decomposed into smaller units.

That is, it might be that it would be useful to be able to compose a
dialog box in Lua from existing components in Wireshark. Something

    dlg = new_dialog_composable("This is my new dialog")
    file_picker = get_wireshark_file_selection_browse();
    add_to_dialog(dlg, file_picker)
    other_stuff = get_wireshark_other_stuff();
    add_to_dialog(dlg, other_stuff)

Anyway, comments welcome.
