You can loop over the columns in your controller's new() method, and initialize it there - that's what the example code below does.

Anyway, I think I need to inform someone of the fact that the
rowHeight has changed.

Yes - I'm surprised to find that you do. I'd have thought that Cocoa would handle this detail when you change the font size - it's usually pretty good about things like that. :-(

    $font  = NSFont->userFixedPitchFontOfSize(0);
    $tmp   = $font->boundingRectForFont()->{size}->{height};
    $table->setRowHeight($tmp);

An NSRect isn't an object - it's just a C struct. It's passed to Perl as a reference to a scalar. You can either dereference it and use unpack(), or call the NSHeight() function to get the height from it.

I did some hacking with the Data Access example, and either a) there's a bug in CB's struct-handling code, or b) I'm misunderstanding what the boundingRectForFont() method does, because I couldn't get a height that made sense from it.

Fortunately, NSFont has a defaultLineHeightForFont() method that *does* return sensible values, as a simple float. Here's what I came up with:

my $font = NSFont->userFixedPitchFontOfSize(12);
my $height = $font->defaultLineHeightForFont();
$self->{'TableView'}->setRowHeight($height);

my $enum = $self->{'TableView'}->tableColumns()->objectEnumerator();
while (my $column = $enum->nextObject()) {
my $cell = $column->dataCell();
$cell->setFont($font);
}
