<h2><a name="overview"></a>Overview</h2>
<p>The commands described in this reference page should only be invoked when
using the package Tablelist_tile. They enable you to set and query the
current theme, to retrieve a list of the available themes, and to make sure
that your widgets will have a theme-specific appearance.</p>

<b>SYNOPSIS</b></dt>
<dd>
<pre>
<b>tablelist::setTheme</b> <i>theme</i>
</pre>
</dd>
<dt><b>DESCRIPTION</b></dt>
<dd>
This command sets the current theme to <code><i>theme</i></code>, loading
it if necessary. It is simply an alias for
<code><b>ttk::setTheme</b></code> or <code><b>tile::setTheme</b></code>,
depending on the tile version loaded into the interpreter. (The
<code><b>tile::setTheme</b></code> command was renamed to
<code><b>ttk::setTheme</b></code> in tile version 0.8.)
<p>Being just an alias for a tile library procedure, the
<code><b>tablelist::setTheme</b></code> command does exactly the same as
the original one: It loads the package implementing the given theme if
needed, sets the theme to the specified one, and saves the latter in the
variable <code><b>ttk::currentTheme</b></code> or
<code><b>tile::currentTheme</b></code>, depending on the current tile
version.</p>

<h2>The <a name="setThemeDefaults"></a>
<code><b>tablelist::setThemeDefaults</b></code> Command</h2>
<dl>
<dt><b>NAME</b></dt>
<dd><code>tablelist::setThemeDefaults</code> - Set theme-specific default
values of some tablelist configuration options</dd>
<dt><br>
<b>SYNOPSIS</b></dt>
<dd>
<pre>
<b>tablelist::setThemeDefaults</b>
</pre>
</dd>
<dt><b>DESCRIPTION</b></dt>
<dd>
This command populates the array
<code><b>tablelist::themeDefaults</b></code> with theme-specific default
values of a series of Tablelist configuration options. The array
names are the command-line names of the options, and the corresponding
array values are the default values of these configuration options for
the currently set tile theme.
<p>The options whose names and values are written into the array
<code><b>tablelist::themeDefaults</b></code> are:
<code><b>-background</b></code>, <code><b>-foreground</b></code>,
<code><b>-disabledforeground</b></code>,
<code><b>-stripebackground</b></code>,
<code><b>-selectbackground</b></code>,
<code><b>-selectforeground</b></code>,
<code><b>-selectborderwidth</b></code>, <code><b>-font</b></code>,
<code><b>-labelbackground</b></code>,
<code><b>-labelforeground</b></code>, <code><b>-labelfont</b></code>,
<code><b>-labelborderwidth</b></code>, <code><b>-labelpady</b></code>,
<code><b>-arrowcolor</b></code>, <code><b>-arrowdisabledcolor</b></code>,
and <code><b>-arrowstyle</b></code>. In addition, the command sets
some other array elements to theme-specific default values of the
background and foreground colors of the column labels in
<code><b>disabled</b></code>, <code><b>active</b></code>, and
<code><b>pressed</b></code> states. (Tablelist needs the label
colors for handling sort arrows and images with transparent background in
the column labels.)</p>
<p>The <code><b>tablelist::setThemeDefaults</b></code> command is invoked
by Tablelist_tile automatically whenever a tablelist widget is createad
or the <code><b><<ThemeChanged>></b></code> virtual event is
received by a tablelist widget. In the latter case, the widget is
reconfigured, using the new default values of those options that were not
set explicitly to values different from the corresponding defaults.</p>
<p>Besides being used by the Tablelist_tile code, this command can also
be invoked in Tcl scripts, still before creating any tile-based tablelist
widget. By calling it explicitly and using the values written by it
into the array <code><b>tablelist::themeDefaults</b></code>, you can make
sure that classical Tk widgets, e.g., listbox and text, will have a
theme-specific appearance, just like the tile widgets. For example,
you can add some common configuration options to the option database as
follows:</p>
<blockquote>
<pre>
tablelist::setThemeDefaults
if {$tile::currentTheme eq "aqua"} {
option add *Listbox.selectBackground \
$tablelist::themeDefaults(-selectbackground)
option add *Listbox.selectForeground \
$tablelist::themeDefaults(-selectforeground)
} else {
option add *selectBackground $tablelist::themeDefaults(-selectbackground)
option add *selectForeground $tablelist::themeDefaults(-selectforeground)
}
option add *selectBorderWidth $tablelist::themeDefaults(-selectborderwidth)
</pre>
</blockquote>
