Public Methods

Method	Description
AdjustForStyleSheet ( Form parent, Control grower, IVwStylesheet stylesheet ) : void	Assumes the control is part of a form and should use a stylesheet. This becomes the stylesheet of the text box. If, as a result, the preferred height of this becomes greater than its actual height, the height of this is adjusted to suit. In addition, if grower is not null (grower is typically a containing panel), the height of grower is increased by the same amount. Also, the height of the indicated form is increased, and any top level controls which need it are adjusted appropriately.
AdjustForStyleSheet ( Form parent, Control grower, XCore mediator ) : void	Adjust, figuring the stylesheet based on the main window of the mediator.
