The FlipChildren method allows you to flip the position of a container control's children. Container controls are controls that can accept other controls, such as TForm, TPanel, and TGroupBox.FlipChildren has a single boolean parameter, AllLevels. When False, only the immediate children of the container control are flipped. When True, all the levels of children in the container control are flipped. 

Delphi flips the controls by changing the Left property and the alignment of the control. If a control's left side is five pixels from the left edge of its parent control, after it is flipped the edit control's right side is five pixels from the right edge of the parent control. If the edit control is left aligned, calling FlipChildren will make the control right aligned. 

To flip a control at design-time select EditFlip Children and select either All or Selected, depending on whether you want to flip all the controls, or just the children of the selected control. You can also flip a control by selecting the control on the form, right-clicking, and selecting Flip Children from the context menu.
