•Alignment;

•ButtonSkinSchemeIndex;

•DrawOnPrint;

•SkinManager;

•SkinSchemeIndex;

•properties inherited from TCustomControl.

New published properties:

Property	Type	Default value	Meaning
AllowGrayed	Boolean	False	Determines whether a check box can be in a “grayed” state. Not supported in a skinned mode.
Checked	Boolean	False	Specifies whether the check box is checked. If the AllowGrayed property is True, you may find it more useful to use the State property.
State	TSRVCheckBoxState	cbUnchecked	Indicates whether the check box is selected (cbChecked), deselected (cbUnchecked), or grayed (cbGrayed)

Painting

A position of the box and Caption depends on Alignment:

•taLeftJustify: the box and the caption is aligned to the left, the box is to the left of the caption;

•taRightJustify: the box and the caption is aligned to the right, the box is to the right of the caption;

•taCenter: the box is in the middle, the caption is aligned to the left.

If SkinManager is assigned, the control is drawn using SkinManager.CurrentSkin.BoxSchemes[SkinSchemeIndex], and the box is drawn using SkinManager.CurrentSkin.BoxSchemes[ButtonSkinSchemeIndex]. In this mode, a grayed state is not supported.
