<h2 id="overview">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>

<h2 id="setTheme">The <code><b>tablelist::setTheme</b></code> Command</h2>
<dl>
<dt><b>NAME</b></dt>
<dd><code>tablelist::setTheme</code> – Set the current theme</dd>
<dt class="tm"><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.)</dd>
<dd class="tm">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.</dd>

</pre>
</dd>
<dt><b>DESCRIPTION</b></dt>
<dd>This command returns the name of the current theme by invoking
the <code><b>ttk::style theme use</b></code> command. If
an old tile version is being used which doesn't yet support this method
then the command returns the value of the variable
<code><b>ttk::currentTheme</b></code> or
<code><b>tile::currentTheme</b></code>, depending on the tile
version. (The namespace containing the variable
<code><b>currentTheme</b></code> was changed in tile version 0.8 from
<code><b>tile</b></code> to <code><b>ttk</b></code>.)</dd>

<dd>This command returns a list of the themes registered in the package
database. It is simply an alias for <code><b>ttk::themes</b></code>
or <code><b>tile::availableThemes</b></code>, depending on the tile version
loaded into the interpreter. (The
<code><b>tile::availableThemes</b></code> command was renamed to
<code><b>ttk::themes</b></code> in tile version 0.8.)</dd>

<h2 id="setThemeDefaults">The <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 class="tm"><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.</dd>
<dd class="tm">The options whose names and values are written into the
array <code><b>tablelist::themeDefaults</b></code> are:
<code><b>-arrowcolor</b></code>, <code><b>-arrowdisabledcolor</b></code>,
<code><b>-arrowstyle</b></code>, <code><b>-background</b></code>,
<code><b>-disabledforeground</b></code>, <code><b>-font</b></code>,
<code><b>-foreground</b></code>, <code><b>-labelborderwidth</b></code>,
<code><b>-labelfont</b></code>, <code><b>-labelforeground</b></code>,
<code><b>-labelpady</b></code>, <code><b>-selectbackground</b></code>,
<code><b>-selectborderwidth</b></code>,
<code><b>-selectforeground</b></code>,
<code><b>-stripebackground</b></code>, and
<code><b>-treestyle</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>normal</b></code>,
<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.)</dd>
<dd class="tm">The <code><b>tablelist::setThemeDefaults</b></code> command
is invoked by Tablelist_tile automatically at application start time and
when the <code><b><<ThemeChanged>></b></code> virtual event is
sent to the main window. It is also invoked on Mac OS 10.14 (Mojave)
and later whenever the main window receives a
<code><b><<LightAqua>></b></code> or
<code><b><<DarkAqua>></b></code> virtual event, if the current
theme is <code>aqua</code>. In these cases, after invoking the
<code><b>tablelist::setThemeDefaults</b></code> command, Tablelist_tile
sends the virtual event
<code><b><<TablelistThemeDefaultsChanged>></b></code> to the
main window and reconfigures all tablelist widgets of the application,
using the new default values of those options that were not set explicitly
to values different from the corresponding defaults.</dd>
<dd class="tm">On Mac OS 10.14 (Mojave) and later, the virtual events
<code><b><<LightAqua>></b></code> and
<code><b><<DarkAqua>></b></code> are sent by Tk 8.6.10 and
later to all toplevel widgets whenever the system appearance toggles
between Light Mode and Dark Mode or the Accent Color in the General
Preferences changes. Tk versions 8.6.11 and later send these events
on Mac OS 10.15 (Catalina) and later also when changing the Highlight Color
in the General Preferences.</dd>
<dd class="tm">Besides being used by Tablelist_tile, this command can also
be invoked in application code, although with current Tablelist_tile
versions there is no need for calling it explicitly.</dd>
<dd class="tm">By using the default option values contained in 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:</dd>
<dd>
<blockquote>
<pre>
if {[tk windowingsystem] eq "x11"} {
option add *selectBackground $tablelist::themeDefaults(-selectbackground)
option add *selectForeground $tablelist::themeDefaults(-selectforeground)
}
option add *selectBorderWidth $tablelist::themeDefaults(-selectborderwidth)
</pre>
</blockquote>
</dd>
<dd>You can also make use of the virtual event
<code><b><<TablelistThemeDefaultsChanged>></b></code> to update
the appearance of your Tk widgets according to the new values contained in
the array <code><b>tablelist::themeDefaults</b></code>, by binding to the
dedicated binding tag <code><b>TablelistMain</b></code> associated with the
main window:</dd>
<dd>
<blockquote>
<pre>
bind TablelistMain <<TablelistThemeDefaultsChanged>> ...
</pre>
</blockquote>
</dd>
<dd>The binding tag <code><b>TablelistMain</b></code> is assigned by
Tablelist_tile to the main window and used internally for handling the
virtual events <code><b><<ThemeChanged>></b></code>,
<code><b><<LightAqua>></b></code>, and
<code><b><<DarkAqua>></b></code>. As shown above,
applications can make use of it, e.g., to handle the virtual event
<code><b><<TablelistThemeDefaultsChanged>></b></code>.</dd>
