<h1>goog.ui.Button</h1>
<fieldset>
<legend>
The first <strong>Button</strong> was created programmatically,
the second by decorating an <strong><input></strong> element:
</legend>
<div id="b1"></div>
<label>
Enable button:<input type="checkbox" id="b1_enable" checked/>
</label>
<br/>
<br/>
<input type="button" id="b2" title="Tooltip extracted from title"
value="My Button" disabled="true"/><br/>
<label>Enable button:<input type="checkbox" id="b2_enable"/></label>
<br/>
</fieldset>
<br/>
<h2>goog.ui.FlatButtonRenderer</h2>
<fieldset>
<legend>
Buttons made with <strong><div></strong>'s instead of
<strong><input></strong>'s or <strong><button></strong>'s
The first rendered, the second decorated:
</legend>
<div id="fb1"></div>
<label>
Enable button:<input type="checkbox" id="fb1_enable" checked/>
</label>
<br/>
<br/>
<div id="fb2" class="goog-flat-button goog-flat-button-disabled"
title="Tooltip extracted from title">My Flat Button</div><br/>
<label>Enable button:<input type="checkbox" id="fb2_enable"/></label>
<br/>
<br/>
<div id="fb3" class="goog-flat-button goog-flat-button-collapse-right">
Combined
</div><div id="fb4" class="goog-flat-button goog-flat-button-collapse-left">
Buttons
</div>
<br/>
</fieldset>
<br/>
<h2>goog.ui.LinkButtonRenderer</h2>
<fieldset>
<legend>
Like FlatButtonRenderer, except the style makes the button appear to be a
link.
</legend>
<div id="lb"></div>
<label>
Enable button:<input type="checkbox" id="lb_enable" checked/>
</label>
</fieldset>
<h2>goog.ui.CustomButton & goog.ui.ToggleButton</h2>
<fieldset>
<legend>
These buttons were rendered using <strong>goog.ui.CustomButton</strong>:
</legend>
<br/>
These buttons were created programmatically:<br/>
<div id="cb1"></div>
<br/>
These buttons were created by decorating some DIVs, and they dispatch
state transition events (watch the event log):<br/>
<div id="cb2">
<!-- On FF2, if you don't enclose the contents of the button in a SPAN,
the bold element isn't rendered. Works on every other browser. -->
<div id="foo" class="goog-custom-button" title="Title specified in HTML">
<span>Decorated <b>Button</b>, yay!</span>
</div>
<div id="bar" class="goog-custom-button goog-custom-button-disabled"
title="Initialized to DISABLED in HTML...">Decorated Disabled</div>
<div id="fee" class="goog-custom-button">Another Button</div>
<div id="btn1"
class="goog-custom-button goog-custom-button-collapse-right">
Archive
</div><div id="btn2" class="goog-custom-button goog-custom-button-collapse-right goog-custom-button-collapse-left">
Delete
</div><div id="btn3"
class="goog-custom-button goog-custom-button-collapse-left">
Report Spam
</div>
</div>
<br/>
Use these <strong>ToggleButton</strong>s to hide/show and enable/disable
the middle button:<br/>
<div id="toggleEnable" class="goog-toggle-button"
title="Click here to enable/disable the button above">Enable</div>
<div id="hideShow"
class="goog-toggle-button goog-custom-button-checked"
title="Click here to hide/show the button above">Show</div>
<br/><br/>
Combined toggle buttons:<br/>
<div id="btn4" class="goog-toggle-button goog-custom-button-collapse-right">
Bold
</div><div id="btn5" class="goog-toggle-button goog-custom-button-collapse-right goog-custom-button-collapse-left">
Italics
</div><div id="btn6" class="goog-toggle-button goog-custom-button-collapse-left goog-custom-button-checked">
Underlined
</div>
<br/>
<br/>
These buttons have icons, and the second one has an extra CSS class:<br/>
<div id="iconbuttons"></div>
<br/>
<span class="hint">
The button with the <span style="font-weight:bold;color:orange;">orange
outline</span> has keyboard focus. Hit Enter to activate focused buttons.
</span>
