TMlSkinAnimation

Notes

• The frames live in Images (an ImageList) and play in order.
• Delay is the interval between frames in milliseconds, Loop repeats the sequence and Reverse plays it backwards.
• CurrentFrame reads and sets the current frame, which lets you position the animation by hand.
• OnFinish fires at the end of a pass and OnProcess on every frame change.

Example

From the demo MlSkin.Demo.动画演示.v3.0 (.dfm form file)

object MlSkinAnimation1: TMlSkinAnimation
  Left = 87
  Top = 200
  Width = 46
  Height = 47
  CurrentFrame = 0
  Images = il1
  Delay = 50
  DoubleBuffered = False
end

Properties of TMlSkinCustomControl 4

Name	Type	Default	Description
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.

Events of TMlSkinCustomControl 4

Name	Type	Default	Description
OnDPIChanged	TMlDPIChangedEvent	—	Fires when the screen DPI changes, for example when the window moves to a monitor with a different scaling — a good place to re-adjust anything you draw yourself.
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.

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.
