Gtk2::Dialog window size

smittypaddler has asked for the wisdom of the Perl Monks concerning the following question:

How do I set the dialog window size so the entire title is displayed. set_size_request wants pixels, and I don't know how to get $title size in pixels. Here's my code:

        $title=($answer eq $Answer) ?  "Yes" : "No, s/b $Answer";
        $dialog=Gtk2::Dialog->new($title,$parent,
                [qw/modal destroy-with-parent/],
                'ok'    => 'ok',
        );
        $response=$dialog->run;
        $dialog->destroy;

Try with this: `$dialog->set_default_size ($width, $height); # or #$dialog->set_default_size (700, 400);` [download] I, personally, would also make the window non-resizable as well.	[reply] [d/l]

set_default_size needs sizes in pixels. I had tried $dialog->set_size_request(500,-1), which worked, sort of. I know the size of my title in characters, but I don't know the width of the font used, so I can only guess at the required width in pixels, hence the 500. If my title is e.g. "No, whatever" I need something that will tell me how many pixels is equivalent to length("No, whatever").	[reply]

its simple, create a "label" widget using the same "system" font with the sane font size as used for the title, let the size be automatic, then "get" the dimensions of the "label" kinda like this Re^3: Query the height of Tk::Text widget with word wrap, Re^7: Query the height of Tk::Text widget with word wrap	[reply]

How do I set the dialog window size so the entire title is displayed. Titles are often clipped, so if that information is important, include it again inside the dialog	[reply]

I solved my problem with this, which granted is simple, but I still think there should be a strait forward one-statement way of determining text size in pixels: `$title=($answer eq $Answer) ? "Yes" : "No, s/b $Answer"; $dialog=Gtk2::Dialog->new($title,$parent, [qw/modal destroy-with-parent/], $title => 'ok', );` [download]	[reply] [d/l]
