This style causes the control to be shifted a small amount to the left from its specified position. The amount is equal to the width of the control's border. This shifting occurs when the control is created or moved. If the control does not have a border, no shifting occurs.

The purpose of this style is to simplify placing several similar controls in a row. For example, if you have a series of adjacent push buttons, the normal appearance would be to draw each push button exactly touching each other. This causes a double border to appear between the push buttons. By shifting each one slightly to the left, you can have the borders overlap and achieve a more uniform appearance with a single border between the buttons. Most applications that have adjacent push buttons do this. You can create the same effect by manually positioning the controls with overlapping borders, but using this style is easier and more portable because you don't need to know exactly how wide the borders are.
