TAdvCustomFormDesigner.OnEndPlacing Event
OnEndPlacing is fired when a place operation is about to be finished, but before the component is effectively placed in the form. This is an opportunity to change the position where the component will be placed. The event handler receives a rect with the position where the component will be placed, and can change that value.
