About | TMlAboutInfo | — | A design-time property: double-clicking it in the Object Inspector opens the MLSkin about box with the component version. It has no effect at run time and is not stored in the .dfm. |
Transparent | Boolean | True | Transparent background: the control skips its own fill and shows the form background (image or color) instead. |
AutoInvalidate | Boolean | False | Repaints automatically when the content changes. Turn it on if property changes do not show up. |
EraseBackground | Boolean | False | Whether the background is erased before painting; worth toggling if the control flickers. |

OnBackgroundChanging | TMlBackgroundEvent | — | Fires just before the background changes, giving you a chance to adjust what is drawn. |
OnBackgroundChanged | TMlCustomDrawEvent | — | Fires after the background has been drawn, so you can paint on top of it. |
OnVisibleChanged | TNotifyEvent | — | Fires when the control is shown or hidden. |
