MF_Widget::MF_Widget(): Constructor Method.
MF_Widget::addRule(): Adds a validation rule to the list of $rules.
MF_Widget::attr(): This is the accessor method for setting and getting the value of
MF_Widget::changeType()
MF_Widget::display(): Returns the display HTML for this widget. The optional parameter determines whether or not to automatically display the widget nicely, or whether to simply return the widget (for use in a template).
MF_Widget::getAttrs(): Returns a list of all of the attributes of this object's HTML tag in a string ready to be concatenated into the actual rendered tag output.
MF_Widget::getValue(): Fetches the actual value for this widget.
MF_Widget::invalid(): Returns a ' class="invalid"' string if the widget's $invalid property is set to true, or an empty string otherwise.
MF_Widget::setDefault(): Sets the default value for the widget.
MF_Widget::setValue(): Sets the *ACTUAL* value for this widget. An optional second parameter can be passed, which is unused here, but can be used in complex widget types to assign parts of a value and piece it together from multiple physical form fields.
MF_Widget::setValues(): Sets the *POSSIBLE* values for this widget. If $value is given, sets $this->value as a hash, otherwise, as a string.
MF_Widget::unsetAttr(): Use this method to remove an attribute from the tag
MF_Widget::validate(): Validates the widget against its set of $rules. Returns false on failure to pass any rule.
MF_Widget::validation(): Sets the validation $rule for this widget. Note: This method is deprecated and only wraps around the addRule() method anyway. Please use addRule() instead, since this method will be removed in a near-future release.
