Attributes

acceltext: Type: string; Text that appears beside beside the menu label to indicate the shortcut key (accelerator key) to use to invoke the command. If this value is set, it overrides an assigned key set in the key attribute. This attribute does not apply to menus directly on the menubar.

accesskey: Type: character; This should be set to a letter that is used as a shortcut key. This letter should be one of the characters that appears in the label text for the element.

Example

<vbox>	
  <label value="Enter Name" accesskey="e" control="myName"/>
  <textbox id="myName"/>
  <button label="Cancel" accesskey="n"/>
  <button label="Ok" accesskey="O"/>
</vbox>

start: The text will be cropped on its left side.
end: The text will be cropped on its right side.
left: The text will be cropped on its left side.
right: The text will be cropped on its right side.
center: The text will be cropped in the middle, showing both the start and end of the text normally.
none: The text will be not be cropped using an ellipsis. However, the text will simply be cut off if it is too large. The side depends on the CSS text alignment.

disabled: Type: boolean; Indicates whether the element is disabled or not. If this element is set to true the element is disabled. Disabled elements are usually drawn with grayed-out text. If the element is disabled, it does not respond to user actions, it cannot be focused, and the command event will not fire.

<!-- Checkbox enables/disables the button -->
<checkbox label="Enable button" 
    onclick="document.getElementById('buttRemove').disabled = this.checked"/>
<button id="buttRemove" label="Remove All" disabled="true"/>

image: Type: image URL; The URL of the image to appear on the element. If this attribute is empty or left out, no image appears. The position of the image is determined by the dir and orient attributes.

label: Type: string; The label that will appear on the element. If this is left out, no text appears.
label 在元素上显示。如果左侧出界，则不显示任何文字。

selected: Type: boolean; Indicates whether the element is selected or not. This value is read-only. To change the selection, set either the selectedIndex or selectedItem property of the containing element.

tabindex: Type: integer; The tab order of the element. The tab order is the order in which the focus is moved when the user presses the "<kbd>tab</kbd>" key. Elements with a higher tabindex are later in the tab sequence.

value: Type: string; The string attribute allows you to associate a data value with an element. It is not used for any specific purpose, but you can access it with a script for your own use.
