TMlSkinRadioBox

Notes

• Radio buttons sharing a GroupIndex are mutually exclusive — selecting one clears the others.
• Checked reads and writes the state and fires OnChanged.
• Pictures supplies the button images.

Properties 5

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.
Pictures	TMlResID	—	The images used by the control, split into frames per state: unchecked, checked, hot, disabled.
Checked	Boolean	False	The checked state.
Light	TMlLightClass	—	Glow effect: switch, glow color and blur radius.
GroupIndex	Integer	0	Group number: buttons sharing a number are mutually exclusive, so only one stays down. 0 means no grouping.

Events 1

Name	Type	Default	Description
OnChanged	TNotifyEvent	—	Fires after the state or value has changed.

Properties of TMlSkinCustomControl 4

Name	Type	Default	Description
Transparent	Boolean	True	Transparent background: the control skips its own fill and shows the form background (image or color) instead.
Color	TColor	clWhite	Background color of the control; ignored while Transparent is on.
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.
