Attributes inherited from XUL Element

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 grippy. This letter will typically be drawn underlined, although this behavior will be platform and skin specific. When the user presses ALT (or a similar key that varies on each platform) and the access key, the grippy will be activated from anywhere in the window.

If the label of the grippy is too small to fit in its given space, the text will be cropped on the side specified by the crop attribute. An ellipsis will be placed in place of the cropped text.

• 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 on both sides.
• none: The text will be not be cropped using an ellipsis. However, the text will simply be cut off if it too large. The side depends on the CSS text alignment.

This attribue can be set to either true or false. If true, then this element becomes the default for the window. Usually, this would be set to true for the OK button and set to false, or left out entirely, for all other buttons. Only one button per window should have the default value set to true.

If this attribute is set to true, the grippy is disabled. This is usually drawn with the text in grey. If the grippy is disabled, the function of the button cannot be performed. The value may also be set to false for a regular active button. If this attribute is left out entirely, the button is enabled.

Indicates the flexibility of the grippy. Flexible elements grow and shrink to fit their given space. The actual value is not relevant unless there are other flexible elements with-in the same container. Elements with larger flex values will grow more than elements with lower flex values, at the ratio determined by the two elements.
