Attributes inherited from XUL Element

accesskey

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 scrollbarbutton. 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 scrollbarbutton will be activated from anywhere in the window.

crop

If the label of the scrollbarbutton 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. If the box direction is right to left (rtl), the cropping is reversed.

- start: The text will be cropped on its left side.
- end: The text will be cropped on its right side.
- left: (Deprecated) The text will be cropped on its left side.
- right: (Deprecated) 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 is too large. The side depends on the CSS text alignment.
