INTRODUCTION

Paved::Tree is an extension of the BWidget-Tree widget.

A Paved-Tree is simply a Tree with a paved (tiled) background.

STANDARD OPTIONS

.. all Tree options are supported.

PAVED-SPECIFIC OPTIONS

-tile image
Specifies an image to display as background, which must have been created with the "image create" command. If image is the empty string, the background is disabled.
-tile filename
filename can be also the name of a supported graphic file ( see [ image types ] )
-bgzoom n
n is an integer value (default 1). With this option, each pixel of the source image will be expanded into a block of n x n pixels.
-tileorigin tuple
tuple is a list with two coordinates describing where the top-left corner of the 'first' tile will be placed in the canvas. Default is { 0 0 }. Each of the coordinates may be specified in any of the valid forms for the 'canvas' COORDINATES. If you have a MxN tile and you want its center be on the point (0,0) of the canvas, specify -tileorigin { M/2 N/2 } (or, equivalently {-M/2 -N/2}, by virtue of coherence properties)

WIDGET COMMANDS

.. all Tree widget commands are supported.

EXTENDED COMMANDS

no extended command.

BINDINGS

EXAMPLE

    package require Paved::Tree
     # suppose xyz.gif is in current directory
    image create photo xyzImage -file xyz.gif 
     # create a tiled-Tree widget; use 'xyzImage' as background.
    Paved::Tree .t -tile xyzImage -borderwidth 10 -relief sunken
    pack .t -fill both -expand true
    .t insert end root #auto -text aaa
    .t insert end root #auto -text bbb
    .t insert end root #auto -text ccc

or in a more compact form: 

    package require Paved::Tree
    Paved::Tree .t -tile xyz.gif -borderwidth 10 -relief sunken
    pack .t -fill both -expand true
    .t insert end root #auto -text aaa
    .t insert end root #auto -text bbb
    .t insert end root #auto -text ccc

NOTES

Paved::Tree is dramatically slow when the wisdget is resized !
