Re: New to GTK+ and a question about Combo boxes.

I'm building a Perk-GTK application on Windows which includes a "date" element, which is three ComboBoxes clustered together in an Hbox: month, day, year.

Since there are several places in the application where a date is added, I built a function to return an Hbox containing those three combo boxes:

sub make_date

[snip packing a bunch of stuff into a new hbox]

   return $hbox;

$E is a global hash I'm using for the time being to keep track of all the elements -- at least until I get more expert with GTK.

My questions:

1) How come whenever I resize the window the ComboBoxes themselves also expand? I've tried every combination in the pack_start function to no avail.

You didn't mention whether they expand vertically or horizontally. If they're expanding vertically, it's not a problem with your hbox packing, but with how you pack the hbox into the window -- if you let the hbox expand inside a vbox, you'll get what i think you're talking about.

If they're still expanding horizontally, please post a bit more code -- just enough that we can run it and play with it.

Screenshots would help.  ;-)

2) How come the pulldown lists appear (for lack of a better term) double spaced? Is there a fix for that?

Do you have newlines in your strings?  Perhaps it's a theme issue?

3) How come I can't seem to get rid of the padding between the three ComboBoxes? I'd like there to be no space between them.

4) One more oddity: if I stick the output of this function in a table cell like this:

$table->attach_defaults(make_date('dob', 1950, 2010), 3, 4, $row, row+1);

and then give the table a small row spacing, like $table- >set_row_spacings(2), the comboboxes expand to like 3x their normal height.

This one sounds like you need to attach() instead of attach_defaults (), and choose the "please don't expand in any direction" options.

zella: At the lavaloli store!
