TMlSkinScrollMsgBar

Notes

• AutoScroll cycles automatically and ScrollInterval sets how long each message stays.
• AnimateEasing picks the easing used between messages (back, elastic, sine and others) and AnimateStep tunes the step size.
• With AllowClick on, clicking a message fires OnItemClick, which can open the matching detail.
• Use OnItemPaint to draw the messages yourself.

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.

Only the properties and events MLSkin adds are listed here. Standard VCL properties such as Align, Anchors, Font and OnClick are available too and behave exactly as on the stock controls.
