DESCRIPTION

Simple DHTML renderer for Data::TreeDumper.

Thanks to Stevan Little author of Tree::Simple::View for giving me the idea and providing some code I could snatch.

EXAMPLE

Check dhtml_test.pl for a complete example of two structure dumps within the same HTML file.

OPTIONS

Style

CSS style is dumped to $setup->{RENDERER}{STYLE} (a ref to a scalar) if it exists. This allows you to collect all the CSS then output it at the top of the HTML code.

  my $style ;
  my $body = DumpTree
  		(
		...
		
  		RENDERER => 
  			{
  			NAME => 'DHTML',
  			STYLE => \$style,
  			},
  		) ;

{RENDERER}{NO_STYLE} removes style section generation. This is usefull when you defined your styles by hand.

  my $style ;
  my $body = DumpTree
  		(
		...
		
  		RENDERER => 
  			{
			NAME => 'DHTML',
  			NO_STYLE => 1,
  			},
  		) ;

Class

The output will use class 'data_tree_dumper_dhtml' for <li> and <ul>. The class can be renamed with the help of {RENDERER}{CLASS}. This allows you to dump multiple data structures and display them with a diffrent styles.

  my $style ;
  my $body = DumpTree
  		(
		...
		
  		RENDERER => 
  			{
			NAME => 'DHTML',
  			CLASS => 'my_class_name',
  			},
  		) ;

Glyphs

Data::TreeDumper outputs the tree lines as ASCII text by default. If {RENDERER}{NO_GLYPH} and RENDERER}{NO_STYLE} are defined, no lines are output and the indentation will be the default <li> style. If you would like to specify a specific style for your tree dump, defined you own CSS and set the appropriate class through {RENDERER}{CLASS}.

Expand/Collapse

Setting {RENDERER}{COLLAPSED} to a true value will display the tree collapsed. this is false by default.

$setup->{RENDERER}{COLLAPSED}++ ;

If {RENDERER}{BUTTON}{COLLAPSE_EXPAND} is set, the rendered will add a button to allow the user to collapse and expand the tree.

$setup->{RENDERER}{BUTTON}{COLLAPSE_EXPAND}

If {RENDERER}{BUTTON}{SEARCH} is set, the rendered will add a button to allow the user to search the tree. This is a primitive search and has no other value than for test.

Bugs

I'll hapilly hand this module over to someone who knows what he does :-)
