Hello Monks,

I'm not sure what wrong I'm doing. Here's a piece of code that demonstrates the problem I'm facing. 

use Tk::Tree;

my $mw = MainWindow->new;
my $tree = $mw->ScrlTree(-indicator=>1,
                         -browsecmd=>\&abba_browse,)
                         ->pack(-fill => 'both', -expand => 1);


my $styleref_select_parent = 
       $tree->ItemStyle('imagetext',               
                        -stylename => 'stylename_select_parent', 
                        -selectbackground=>'cyan',
                        -selectforeground=>'blue',
                        -font=> [-family => 'Linotype Birka',
                               -size => 20,
                               -weight => 'bold',
                               -slant => 'roman',
                               -underline => 1,
                               -overstrike => 1]);

     
my $styleref_select_child = 
         $tree->ItemStyle('imagetext', 
                          -stylename => 'stylename_select_child', 
                          -selectbackground=>'cyan',
                          -selectforeground=>'red',
                          -font=> [-family => 'Linotype Birka',
                                   -size => 10,
                                   -weight => 'bold',
                                   -slant => 'roman',
                                   -underline => 0,
                                   -overstrike => 0]);
     
$tree->add('ABC', -text => 'Text is: ABC', -state=>'normal');
$tree->add('ABC.def', -text => 'Text is: def', -state=>'normal');
$tree->add('ABC.def.ghi', -text => 'Text is: ghi', -state=>'normal');
        
$tree->setmode();
$tree->close('ABC.def');
        
my $tree_element;
MainLoop;

sub abba_browse {        
     $tree_element = $tree->info('selection')->[0];
     if ($tree_element eq 'ABC') { 
            $tree->entryconfigure($tree->info('selection'),
                                  -style=>$styleref_select_parent);
            }
     else {
            $tree->entryconfigure($tree->info('selection'),
                                  -style=>$styleref_select_child); 
            }        
                     
}

Question 1:
        When I click on the parent entry 'Text is ABC', the ItemStyle configured for this entry doesn't get applied. i.e. while the  -selectbackground doesn't work at all, the values of the  -font option applied are those configured for the child . Why is this so ?

Question 2:
        In the code if I move the declaration for  $styleref_select_parent past that of  $styleref_select_child then only those of the parent are applied to that of child as well. Is it then that only the last declaration which sets the  -font option is considered ?

Question 3:
        Just like we can configure the font for each of the display item in the tree via the -font option, is there a way to configure the size of the indicator in tandem with font for the text entries in the tree ?


BTW: I'm using,
        Strawberry Perl version: 5.16.3
        ItemStyle.pm version: 4.004
        Tree.pm version: 4.72

Many Thanks
