Left: Position of the upper-left corner of the control in the layout, in relation to the horizontal axis of the layout space.
Top: Position of the upper-left corner of the control in the layout, in relation to the vertical axis of the layout space.
Width: Percentage of layout space occupied by the control, starting from the Left value. In the example above, the Preview control occupies the 25% of the layout's width. Since the Left value is set to 25%, the control width starts from 25% and ends at 50% of the layout's width.
Height: Percentage of layout space occupied by the control, starting from the Top value. In the example above, the Preview control occupies the 25% of the layout's height. Since the Top value is set to 50%, the control height starts from 50% and ends at 75% of the layout's height.
