DynaTab Hide error

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

I am trying to use the DynTabFrame. I have created a DynaTab with the following

$dynatab_name = 'SNG';
dynatab_frame_child($tab_Tabbed, \$tabbed_frame{$dynatab_name}, $dynat
+ab_caption, $dynatab_title, $dynatab_image, $dynatab_colour , $dynata
+b_raised_colour);
[download]

$tab_tabbed has been created as a DynaTabFrame

This is the code for the dyantab_frame_child

sub     dynatab_frame_child($$$$$$$) {
my ($tab_parent, $ref_child, $dynatab_caption, $dynatab_title, $dynata
+b_image, $dynatab_colour ,$dynatab_raised_colour) = @_;
$$ref_child = $tab_parent->add(
                -caption => $dynatab_caption, 
                -label    => $dynatab_title,
                -tabtip => "Tip for tabno",
            )
            ->pack()
            ;
}

The following is a sub where I am trying to hide this tab frame using the sub hid_tab called from a button

sub hide_tab() {

my ($hidden_value, $dynatab_name);

$dynatab_name = 'SNG';

print "\n[hide_tab] entered\n";

$hidden_value = $tabbed_frame{$dynatab_name}->cget(-hidden);

print "\n[hide_tab] for $dynatab_name - $hidden_value <$hidden_value>\
+n";

if(length($hidden_value) == 0) {

    print "\n[hide_tab] hiding $dynatab_name - $hidden_value <$hidden_
+value>\n";

    $tabbed_frame{$dynatab_name}->configure(-hidden => 1);
}
}
[download]

This is the error I get in the hide_tab sub

[hide_tab] hiding SNG -  <>
Tk::Error: Can't set -hidden to `1' for Tk::Frame=HASH(0x20f90157e48):
+ unknown option "-hidden" at C:.....
[download]

What am I doing wrong?

The pod for DynaTab has:

-hidden
When set to a true value, causes the resulting tab to be hidden from view; can later be set to a false value to force the tab to be visible again.

G'day merrymonk, The Tk::DynaTabFrame documentation does not give `-hidden` as a widget option. The "... unknown option "-hidden" at ..." message that you received is quite correct. If you look in the METHODS section of that documentation, you'll see that the methods `add()`, `pagecget()` and `pageconfigure()` support a `-hidden` option. — Ken	[reply] [d/l] [select]

Many thanks for you and others pointing me in the right direction. Will try again tomorrow.	[reply]

I now have tried to use the pagecget and pageconfigure Methods. However, for both I get the error Tk::Error: Failed to AUTOLOAD 'Tk::Frame::pageconfigure' at ... line nn in Perl script I notice two things: 1. the pod's description of add (which I use to create the dyna tabbed frame) is Adds a page with name pageName (if provided) to the notebook. Returns an object of type Frame. 2. the Error mentions Tk::Frame so I guess it is looking in Tk::Frame rather than Tk::DynaTabFrame which contains the sub pageconfigure I guess there are two questions (an answer to either may solve the problem): 1. Is there an alternate to add to create the DynaTab frame which creates a DynaTabFrame object - I could not see one 2. How can I get the application to use pagecget and pageconfigure from the DynaTabFrame module So an answer to either or even another solution would be much appreciated.	[reply]

No idea what you are talking about. I searched for DynTabFrame with no result. DynaTab has a result for Prisma, but at the end you talk about Tk badly formated, lazy worded ... again -> downvoted	[reply]

Sorry my question was not as clear as it should have been and was not 'formatted' correctly! The question is about the DynaTabFrame - (there were refereces to DynaTab elsewhere which may have been a clue). So help with the DynaTabFrame would be appreciated.	[reply]

"...So help with the DynaTabFrame would be appreciated." That's O.K. As asking questions is what the Monastery was made for. Here is a link for the uninitiated or Tk::DynaTabFrame - as you like. Else we will get some stuff about pet food, drugs or what ever. BTW, being a little bit more precise might be a pleasure. �The Crux of the Biscuit is the Apostrophe�	[reply]
