When the integralHeight property of TextBox controls and ListBox controls is set to true, the control height is determined by multiples of text height (that is, a multiple of the character size of the text displayed in that control). When this property is set to false, the control height is not determined by the text height.
By default, the integral height of both single line and multiple line text box controls is set to false and the integral height of list box controls is set to true.
As the text box does not show partial text lines when the integralHeight property is set to false, the control offsets the text area from the top (that is, any extra space appears at the top of the text box).
The integralHeight property is ignored if the parent of TextBox and ListBox controls has the alignChildren property set.
